Introduction

Hypertension and hypertension-mediated organ damage (HMOD) contribute considerably to disability and global mortality [1, 2]. Hypertension-induced structural and/or functional changes in major organs are associated with increased risks of a number of conditions including arrhythmias, coronary artery disease (CAD), myocardial infarction, and congestive heart failure.

Hypertension burden in Russia is one of the highest in the world [3], with significant associated economic costs [4]. In the frame of the Russian participation in the 2017 global May Measurement Month (MMM) initiative, 5660 individuals were screened of whom 2709 (47.9%) were found to have hypertension [5]. This is in line with data from another Russian epidemiological study, ESSE-RF, where hypertension prevalence was 44.2% [6]. Among treatment-naïve patients, the prevalence of hypertension was 20.3%, and among those receiving antihypertensive medication, 55.9% had uncontrolled blood pressure. Comparison of the Russian results with worldwide 2017 MMM data revealed that Russian participants had a higher proportion of hypertension, comparable antihypertensive prescription rates, and worse hypertension control [5]. To improve hypertension control and cardiovascular outcomes, strategies therefore need to focus on levels of modifiable risk factors in the population and on encouraging patients to adhere better to lifestyle changes and prescribed treatments.

The most recent European Society of Cardiology (ESC)/European Society of Hypertension (ESH) and Russian guidelines for the management of arterial hypertension consider anyone with a blood pressure greater than 140/90 mmHg a candidate for treatment, with a goal of 130/80 mmHg or lower in most patients [7, 8]. To achieve this target, a single-pill combination of two antihypertensive agents is recommended first-line in all patients except low-risk grade I and the frail elderly [7].

Patients with HMOD are at very high risk of cardiovascular events, yet many struggle to achieve optimal control. Data from the EUROASPIRE IV study conducted in 24 European countries indicated that six out of ten patients with CAD were not reaching their blood pressure targets [9]. By combining antihypertensive agents with different modes of action, physicians can improve the likelihood of blood pressure targets being achieved and provide individuals with the best protection against HMOD or limit its progression.

An optimal treatment in patients with hypertension and CAD would combine beta-blockers that target hypertension driven by the sympathetic nervous system with angiotensin-converting enzyme (ACE) inhibitors that target hypertension driven by the renin–angiotensin–aldosterone system. This provides a comprehensive neuroendocrine blockade, reducing cardiac output at the same time as inducing vasodilation, thus managing the symptoms of angina as well as lowering blood pressure. Data on the cardiovascular benefits of such a combination have already been provided by the EUROPA trial, which randomized over 12,000 patients with stable CAD to perindopril or placebo (62% of whom were on beta-blockers) [10]. The addition of perindopril to a beta-blocker was associated with a 24% reduction in relative risk of the combined primary endpoint (cardiovascular death, non-fatal myocardial infarction, and resuscitated cardiac arrest) compared with the beta-blocker/placebo group [11]. Similar findings were observed in a retrospective pooled analysis of patients from three large perindopril outcome trials (EUROPA, ADVANCE, and PROGRESS) who received perindopril or placebo and were already on beta-blocker therapy [12]. Hypertension and CAD are predominantly managed in the outpatient setting. Bisoprolol is the most used beta-blocker in patients with stable angina and hypertension in Russia (up to 48.9%) [13], and perindopril is the most used ACE inhibitor in Russian patients with hypertension [14].

The STYLE observational study was conducted to obtain real-world data on the antihypertensive and antianginal benefits of using a single pill combination (SPC) of bisoprolol and perindopril in patients with hypertension and stable CAD treated in daily clinical practice.

Methods

STYLE was a multicenter, open-label, prospective, observational, uncontrolled study conducted between November 2018 and October 2019 in Russian clinical practice. General practitioners and cardiologists with outpatient practices included adult patients with arterial hypertension and concomitant stable CAD (defined as stable class I–III angina according to the Canadian Cardiovascular Society [CCS] classification). Decisions on prescription of the SPC of bisoprolol and perindopril according to the summary of product characteristics (SmPC) were made before recruitment in the program.

Exclusion criteria were stable angina class IV or unstable angina within the past 6 months, a history of myocardial infarction or cerebrovascular accident within the past 3 months, New York Heart Association (NYHA) class III to IV heart failure, type 1 diabetes mellitus or decompensated type 2 diabetes mellitus, any serious decompensated concomitant diseases requiring regular medical treatment, inability to understand the nature of the program and follow the recommendations, participation in another study within 30 days of the start of the observational program, and any contraindications to ACE inhibitors and/or beta-blockers.

The study was performed in accordance with good clinical practice and the ethical principles derived from the revised Declaration of Helsinki. Institutional ethics committee approval was sought before performing the study and all patients provided written informed consent.

Subjects were requested to make three visits to the study site: an inclusion visit (V1), 1-month follow-up visit (V2), and 3-month follow-up visit (V3). At V1 the investigators collected patient demographic data as well as information on risk factors, history of cardiovascular events, blood pressure, resting heart rate (HR), angina functional class and number of angina attacks, presence of symptoms of heart failure and functional NYHA heart failure class, and current cardiovascular treatments. Data on systolic and diastolic blood pressure (SBP and DBP), and HR were collected at all three visits. Office blood pressure was measured on the right arm after 5 min of rest with the patient in a sitting position using the Korotkoff method. Three measurements were performed at 1–2 min intervals, after 5 min of rest. SBP, DBP, and HR values were taken as the mean of the last two readings. If there were differences between two consecutive measurements of SBP of 15 mmHg or more, repeated measurements were performed. During the study, the investigators collected subjective data from patients on treatment adherence and tolerability. In addition, patients kept a diary in which they reported number of angina attacks, consumption of short-acting nitrates, and any adverse events. Quality of life was assessed at each visit by patients, using a 100-mm visual analog scale (VAS) on which 0 was worst quality of life and 100 was quality of life associated with perfect health.

At the inclusion visit patients were on bisoprolol and perindopril SPC, or on free combination of bisoprolol and perindopril, or on bisoprolol and perindopril monotherapy with intention before inclusion in the study to switch to SPC. Patients received bisoprolol/perindopril at one of the following five doses: 2.5/2.5 mg, 2.5/5.0 mg, 5.0/5.0 mg, 5.0/10.0 mg, or 10.0/ 10.0 mg.

The primary study endpoints included measures of antihypertensive and antianginal effectiveness including change in mean office SBP and DBP, proportion of patients achieving a target blood pressure of less than 140/90 mmHg (proportion of patients achieving a target BP of less than 130/80 mmHg was added after publication of the ESC/ESH guidelines for the management of arterial hypertension in 2018 [7]), change in number of angina attacks per week, and change in consumption of short-acting nitrates. HR and correlations between changes in HR and number of angina attacks and consumption of short-acting nitrates were also assessed. Secondary endpoints included the effect of treatment on quality of life and assessment of treatment adherence. The latter was assessed using a non-validated questionnaire in Russian comprising six questions where the answer of “no” to all questions indicated good adherence, “yes” to one or two questions indicated minor adherence, and “yes” to three or more questions indicated non-adherence [15]. Subjective assessments of effectiveness and tolerability were also performed by both physicians and patients at V3. Adverse events were assessed at each visit and recorded in the patient diary.

Statistical Analysis

Data were analyzed using R statistical software [16]. All study parameters were presented using descriptive statistics including mean, standard deviation, 95% confidence intervals, or as absolute number and relative frequency of occurrence of each possible value for qualitative or categorical variables. Analyses were performed on the full analysis set (FAS). Changes in the mean weekly dose of short-acting nitrates were evaluated only in patients with available values. Before and after treatment values with a normal distribution were compared using the Student’s t test for paired observations; the Wilcoxon non-parametric test was used for those that did not follow a normal distribution. A value of P < 0.05 was considered statistically significant. Adverse events were assessed in all patients who received a dose of study drug.

Results

A total of 370 GPs and cardiologists recruited 1909 patients to take part in the STYLE observational program. Seventeen patients did not meet the inclusion criteria and therefore 1892 patients were included in the FAS of whom 1873 completed the study. Reasons for withdrawal for 19 patients were patient’s decisions (n = 4), adverse events (n = 3), did not attend follow-up visit (n = 2), lost to follow-up (n = 1), physician’s decision (n = 1), and reason not stated (n = 8).

Demographic and baseline clinical characteristics are shown in Table 1. Mean age was 61.9 ± 8.8 years. There were 874 (46.2%) men and 1007 (53.2%) women; no gender was indicated in 11 participants (0.6%).

Table 1 Baseline patient demographics and clinical characteristics
Full size table

The mean SBP and DBP values at baseline were 158.3 ± 14.6 mmHg and 93.1 ± 9.2 mmHg, respectively, and resting HR was 82.5 ± 10.1 bpm. The majority of patients (85%) had grade 2 or 3 hypertension (defined as blood pressure higher than 160/100 and 180/110 mmHg, respectively), and mean duration of hypertension was 12.5 ± 7.9 years. CCS class I angina had been diagnosed in 23.6% of patients, class II in 61.1%, and class III in 7.2%. The mean duration of CAD was 7.2 ± 6.4 years.

In addition to hypertension, 75.6% had dyslipidemia, 15.8% had type 2 diabetes, 26.6% were current smokers, 66.0% did not perform regular physical exercise, and 38.9% had a family history of cardiovascular disease. Concomitant cardiovascular diseases were prevalent: 84.2% had left ventricular hypertrophy, 76.0% had NYHA class I–II congestive heart failure, 26.2% had a history of myocardial infarction, 19.7% a history of coronary revascularization, and 7.3% a history of stroke or transient ischemic attack.

At the baseline visit, 89% of patients (n = 1684) were already on SPC bisoprolol and perindopril, 1.7% (n = 33) were on free combination of bisoprolol and perindopril followed by prescription of SPC, 7% (n = 132) were on bisoprolol monotherapy followed by prescription of SPC, and 0.9% (n = 17) were on perindopril monotherapy followed by prescription of SPC. For 26 patients (1.4%) the type of therapy with perindopril and bisoprolol was not described. All decisions on switching from free combination or monotherapy to SPC bisoprolol and perindopril were taken independently and before inclusion in the study. The most frequently prescribed SPC dose was 5.0/10.0 mg (33.5%), followed by 5.0/5.0 mg (26.3%), and 10.0/ 10.0 mg (16.1%). The proportions of patients receiving these doses increased slightly at V2 (38.8%, 28.5%, and 22.1%, respectively) and then remained relatively constant for the rest of the study (Table 2).

In addition to this treatment, patients were receiving a range of cardiovascular drugs including beta-blockers, calcium channel blockers, diuretics, ACE inhibitors and angiotensin receptor blockers, and imidazole receptor agonists (Table 1). Patients prescribed other antihypertensive regimens received the SPC in addition to their existing therapy. Statins were prescribed in 76.6%, antithrombotic therapy (78.5%), trimetazidine (34.4%), ivabradine (3.5%), short-acting nitrates (34.0%), and long-acting nitrates (12.4%) (Table 1). During the study, no statistically significant changes in these concomitant treatments nor their doses were observed, except for statin treatment for which the number of patients taking atorvastatin 20 mg or 40 mg and simvastatin 10 mg or 20 mg increased.

There were no statistically significant changes between visits in the doses of other background antihypertensive treatment while patients were receiving the bisoprolol/perindopril SPC.

Primary Effectiveness Parameters

Mean SBP decreased from 158.3 ± 14.6 mmHg at baseline to 136 ± 11.9 mmHg at V2 (22.3 ± 13.1 mmHg reduction) and to 126.9 ± 8.4 mmHg at V3 (31.5 ± 14.2 mmHg reduction) reaching the target set by the new guidelines (Fig. 1). The reduction in SBP was statistically significant between baseline and V2 and baseline and V3 (both P < 0.0001), but not between V2 and V3 suggesting that most of the SBP reduction occurred within the first month of treatment. Similarly, mean DBP decreased from 93.1 ± 9.2 mmHg at baseline to 82.1 ± 7.6 at V2 (11.0 ± 9.1 mmHg reduction) and to 77.2 ± 6.2 at V3 (15.9 ± 9.5 mmHg reduction) (both P < 0.0001) (Fig. 1). The difference between V2 and V3 did not reach statistical significance.

The proportion of patients achieving the target blood pressure level (SBP < 140 mmHg and DBP < 90 mmHg) at V2 was 49.2% (Fig. 2). At V3 this had increased to 86.7%. The proportion of patients meeting the target of less than 130/80 mmHg was 20.1% at V2 and 31.9% at V3 (Fig. 2).

The average number of angina attacks per week was 3.7 ± 8.5 at baseline, 1.3 ± 2.2 at V2, and 0.5 ± 1.2 at V3. Reductions were statistically significant between baseline and V2 and baseline and V3 (P < 0.0001) (Table 3). The mean consumption of short-acting nitrates (tablets/sprays) per week was reduced from 4.0 ± 4.3 at baseline to 2.1 ± 2.4 at V2, and 1.0 ± 1.5 at V3, which were statistically significant for V2 and V3 compared with baseline (P < 0.0001) (Table 4).

Secondary Effectiveness Parameters

At baseline, the mean resting HR was 82.5 ± 10.1 bpm. After 1 month of bisoprolol/perindopril SPC, resting HR had decreased by 13.5 ± 9.0 bpm to 69.0 ± 7.5 bpm (P < 0.0001), and after 3 months had decreased by 17.7 ± 9.7 bpm to 64.9 ± 5.5 bpm (P < 0.0001) (Fig. 3). No significant correlation was found between the HR reduction and the reduction in the number of angina attacks in the periods between visits 2 and 1, and visits 3 and 1. A weak but statistically significant positive correlation was observed between the HR reduction and the number of angina attacks between V2 and V3 (the correlation coefficient was 0.047, P < 0.0001). The HR reduction during the study was also associated with a slight decrease in nitrate consumption in this cohort of patients with hypertension and stable CAD. The correlation coefficient was 0.039 (P = 0.004) for the period from visit 1 to visit 2, 0.0617 (P = 0.002) for the period from visit 1 to visit 3, and 0.0624 (P < 0.0001) for the period from visit 2 to visit 3.

At baseline the proportion of patients with resting HR less than 60 bpm as recommended by guidelines was 1.5%. However, an increase in patients achieving the target level of resting HR was observed at V2 and V3 (12.6% and 24.7%, respectively). Changing the dose of bisoprolol/perindopril SPC had little effect on the reductions in the mean HR values (Table 5).

Treatment with the bisoprolol/perindopril SPC significantly improved patient quality of life according to the VAS with an increase in mean score from 47.2 ± 17.4 mm at baseline to 67.9 ± 14.3 mm at V2 (P < 0.0001) and 82.4 ± 13.3 mm at V3 (P < 0.0001) (Fig. 4).

At V2, just over half the participants (52.4%) had minor adherence, 37.2% of patients had good adherence, while 10.1% of participants did not follow physicians’ recommendations at all (non-adherent). At V3, the proportion of patients with good adherence had increased to 57.1%, while the proportion of participants who were non-adherent had decreased significantly to 2.8%. The proportion of patients with minor adherence decreased to 39.4%. A subjective assessment of effectiveness and tolerability was also performed by both physicians and patients at V3. Physicians reported treatment effectiveness was “excellent” in 65% of patients and “good” in 32%. In comparison, patient ratings for treatment effectiveness were “excellent” in 54.5% and “good” in 41.4%. Physicians rated tolerability as “excellent” in 68.2% of patients and “good” in 29.4%. The proportions of patients reporting “excellent” or “good” tolerability were 58.0% and 38.5%, respectively.

Safety

The profile of reported adverse events corresponded with the well-known safety profile of the individual drug components and characteristics of the included patients. No new safety issues were identified. During the study, physicians recorded nine adverse events in four patients (0.2%). In three patients the adverse drug reaction resulted in withdrawal of bisoprolol/perindopril SPC. Two patients receiving the SPC at a dose of 5 mg/5 mg experienced arterial hypotension with dizziness and bradycardia, one of them also had an episode of syncope. These events were considered to be causally related to study drug and in one patient resulted in the SPC being taken periodically and not daily, which did not comply with the instructions for medical use.

One patient experienced a dry cough and tingling throat during the treatment which was also treatment related. The fourth patient experienced a non-traumatic vertebral compression fracture that required hospitalization followed by death of unknown cause. This event was not related to study drug.

Discussion

The results of the STYLE observational study provide important data on the characteristics of patients with hypertension and stable CAD treated in a Russian outpatient setting. Analysis of the baseline characteristics of this population revealed a high prevalence of cardiovascular disease risk factors and multiple HMOD. Despite this, mean blood pressure at baseline was 158/93 mmHg and mean resting HR was 82.5 ± 10.1 bpm, well above recommended targets [17]. Following the switch to or addition of bisoprolol/perindopril SPC to the patients’ antihypertensive regimens, reductions in mean blood pressure of 22/11 mmHg at V2 and 32/16 mmHg at V3 were observed. At each visit the reductions were statistically significant compared with baseline, but not between the visits. This suggests that blood pressure reductions occurred early after initiation of treatment, an important consideration in a population at high cardiovascular risk. By V3, 86.7% of the study population had achieved the target blood pressure level of less than 140/90 mmHg, but as the most recent ESC/ESH guidelines were published during the study it was also decided to evaluate the proportion of patients achieving the new target of less than 130/80 mmHg. The proportion achieving this target was 31.9% at V3. This analysis was performed on the FAS and did not take into consideration factors such as age and treatment tolerance that can have an impact on target blood pressure goals. In the current study, treatment was well tolerated and so unlikely to be a factor. Two potential reasons for achievement of the new blood pressure goals in only a third of the study population are (1) that most physicians were still following the previous blood pressure goals (less than 140/90 mmHg) in routine clinical practice; and (2) that a proportion of the patients were older than 65 years and had a higher target blood pressure range.

During the study there were no statistically significant changes in the concomitant antihypertensive treatments or their doses, nor in other types of concomitant medication such as statins. The changes in blood pressure observed were therefore likely a result of the addition of the SPC to the treatment regimen.

Although HR is not included in any cardiovascular risk algorithm, it remains an independent predictor of cardiovascular morbidity and fatal events [18], yet only 14.7% of patients were receiving a beta-blocker at baseline and only 3.5% were receiving ivabradine. These data corroborate findings from other observational studies and registry analyses [19, 20]. In the CLARIFY registry, a large, international, observational, longitudinal registry of outpatients with stable CAD, nearly half the CAD registry population had a HR of at least 70 bpm despite three quarters receiving treatment with beta-blockers [20]. Furthermore, a HR of at least 70 bpm was found to be independently associated with a higher prevalence and severity of angina, and more frequent evidence of myocardial ischemia [20].

In patients with CAD, HR control is the first and most important step to achieve symptomatic control of stable angina, and beta-blockers are a first-line therapy to achieve this goal. Following the addition of the SPC with a bisoprolol component, a statistically significant reduction in HR was observed at both the 1- and 3-month visits compared with baseline. In another Russian cross-sectional, observational study with a similar population (ATHENA, AchievemenT of target resting HEart rate on beta-blockers in patients with stable angiNA and hypertension), patients with a median duration of beta-blocker treatment of 24.0 months (range 2.0–257.0) had only slightly higher resting HR (68.8 bpm, range 48.0–109.7) vs 64.9 bpm (range 46–100) after 3 months of treatment with bisoprolol/perindopril SPC [13].

Meanwhile, in the STYLE study, a higher proportion of patients achieved the resting HR of 55–60 bpm recommended by the 2019 ESC guidelines for the diagnosis and management of chronic coronary syndromes [17] after 3 months of SPC treatment—24.3% in STYLE vs 15.5% in ATHENA [13]. This could possibly be due to the slightly higher doses of beta-blockers used in STYLE. A rather low proportion of HR goal achievement in both studies can be explained by the fact that beta-blockers were used in low doses compared with those used in landmark clinical trials [21]. However, they correspond to the daily beta-blocker doses reported in a pan-European observational study of patients with stable angina [22]. A possible explanation of HR non-achievement is undertitration of beta-blocker dose because of adverse event fears and de-prioritization of HR as a treatment target for stable angina. Meanwhile, correlation coefficients between the reduction in HR and dose of bisoprolol/perindopril SPC were negative and close to 0; therefore, changing the dose of bisoprolol/perindopril SPC had little effect on reductions in mean HR values.

The addition of bisoprolol/perindopril SPC to the treatment plan also led to a reduction in the number of angina attacks and short-acting nitrate consumption, and this reduction was again statistically significant between baseline and the individual treatment visits. Furthermore, a weak but statistically significant positive correlation was observed between HR reduction and short-acting nitrate consumption. These data confirm findings from the ATHENA study in which patients achieving target HR had a significantly lower frequency of nitroglycerin-only administration compared with patients not achieving target (1.5% vs 3.0%, P < 0.045) [13].

Angina has an adverse effect on quality of life because of factors such as pain, limited exercise tolerance, and poor general health status [23]. Any reduction in the frequency or severity of angina symptoms would therefore be expected to improve quality of life as long as it was not associated with other adverse effects. In the current study, treatment with the bisoprolol/perindopril SPC significantly improved patient quality of life according to the VAS with an increase in mean score by 20.7 mm between baseline and V2, and an increase by 35.2 mm between baseline and V3; a change by 10 mm on a 100-mm VAS is considered clinically significant [24].

In the past few years greater emphasis has been placed on the prescription of effective pharmacological interventions that promote patient adherence [7, 25]. Combining agents with complementary mechanisms of action into a single pill is one solution that offers several advantages over the individual components taken separately [26]. These include more rapid reductions in blood pressure, a greater likelihood of achieving treatment targets, improved tolerability compared with uptitrating the dose of single agents, and a simplified dosing regimen, all of which favor adherence to the treatment [27,28,29]. This was reflected in the current study with adherence increasing throughout the study so that at V3, 57.1% had good adherence and 39.4% minor adherence; only 2.8% were non-adherent, perhaps owing to the multiple concomitant medications they were taking. Only three patients experienced treatment-related adverse events that resulted in study drug withdrawal. In addition, physicians confirmed tolerability of the single-pill combination was “good” to “excellent” in 97% of patients, which was corroborated by 96.5% of patients.

This study was subject to the inherent limitations of observational studies, which include sample bias, incomplete response data, as well as to the potential inaccuracy of self-reported behavior. As an observational study without a control arm, blinding, and no randomized treatment allocation, this study does not attempt to make any causal inferences about treatment effect. In addition, the 3-month duration of the study, while being sufficient to observe an effect of the SPC on blood pressure and HR, was not long enough to provide any information on cardiovascular events and long-term adverse effects. Nevertheless, the population sample size was large and the findings have important implications for the treatment of a wide range of patients with hypertension and stable CAD in clinical practice.

Conclusion

The STYLE observational study results support the addition of a bisoprolol/perindopril SPC to standard antihypertensive therapy to simultaneously reduce blood pressure and HR in patients with hypertension and stable CAD and to allow more patients to achieve blood pressure treatment goals. The beneficial effects of the SPC on these risk factors were accompanied by improvements in angina symptoms and quality of life. The treatment was well tolerated in a broad patient population representative of those seen in everyday clinical practice. Meanwhile, these data indicate that physicians should pay more attention to resting HR management in patients with stable angina.
