Insights
Adding ivabradine to standard treatment significantly reduced angina attacks, heart rate, and hospitalizations in post-myocardial infarction patients. This therapy improved quality of life and demonstrated a favorable safety profile.
Area of Science:
- Cardiology
- Pharmacology
- Clinical Medicine
Background:
- Patients with myocardial infarction and angina often experience persistent symptoms like elevated heart rate and angina attacks despite standard treatment.
- Current therapeutic strategies aim to improve symptom control, reduce cardiovascular events, and enhance the quality of life for these patients.
Purpose of the Study:
- To evaluate the effectiveness and safety of adding ivabradine to standard therapy in patients with a history of myocardial infarction and ongoing angina.
- To assess the impact of ivabradine on heart rate, angina frequency, quality of life, and healthcare utilization.
Main Methods:
- An observational study involving 1226 patients across 53 cities in the Russian Federation.
- Patients received ivabradine in addition to their existing treatment for 16 weeks.
- Data collected included heart rate, blood pressure, angina attack frequency, nitroglycerin use, ambulance calls, hospitalizations, and quality of life assessments.
Main Results:
- Adding ivabradine led to a significant reduction in heart rate (from 84.5 to 63.1 bpm) and weekly angina attacks (from 8.17 to 1.27).
- There was a marked decrease in ambulance calls (35.6% to 1.5%) and hospitalizations (15.4% to 1.2%).
- Patient-reported outcomes showed significant improvements in treatment effectiveness, risk stratification, state stability, and prognosis, alongside enhanced quality of life.
Conclusions:
- The addition of ivabradine to beta-blocker therapy is a rational and safe treatment strategy for patients with myocardial infarction and angina experiencing elevated heart rate.
- Ivabradine effectively reduces symptoms, improves clinical outcomes, and enhances the quality of life in this patient population.
- The observed benefits were significant and appeared early in the treatment course, with a low incidence of drug-related adverse effects.
Abstract:
The results of Assessment Program effective treatment of patients with myocardiaL INfarction drug ProCORalan (ivabradine) in outpatient practice, conducted in 53 cities of the Russian Federation, 333 doctors. Included 1226 patients (822 men and 404 women, average age 60,1+/-9,3 years). Despite treatment, before inclusion in the patients maintained an average 8,17+/-8,60 (mediana 6) angina attacks per week, elevated blood pressure (141,8+/-20,3/86,2+/-11,6 mm Hg) and heart rate (84,5 +/-10,4 beats / min). Adding to ivabradine treatment for 16 weeks resulted in significant (p<0.00001) reduction in heart rate (up to 63,1+/-7,5 beats / min), the number of angina attacks per week (from 8.17 to 1.27) and need for nitroglycerin (from 7.69 to 0.89 tablets per week). Decreased the number of patients that called ambulance assistance (from 35.6 to 1.5%), and hospitalization (from 15.4 to 1.2%). There was a significant (p<0.00001) increase in evaluating the effectiveness of treatment (from 5,4+/-1,8 to 8,9 +/-1,3 points), reducing the risk stratification of patients (6,1+/-1,5 to 4 3+/-2,0 points), increased stability evaluation of state (from 5,6+/-1,9 to 3,7+/-2,2 points) and improved assessment of prognosis (from 5,7+/-2,0 to 3,6 +/-1,9 points). Expressed significantly positive effects observed after 1 month of therapy, after the effect became more pronounced. Significantly improved quality of life estimated by Seattle Angina Questionnaire and Minnesota Living with Heart Failure. The maximum recommended dose ivabradine of 15mg/day were given 50% of the patients, the dose of 10 mg/day - 28%. Adverse effects were reported in 3.3% of patients, of which, according to doctors associated with taking the drug - 0.82%. During follow up, 4 patients died. Thus, the addition of ivabradine to -blocker therapy, persons with a history of myocardial infarction and angina experiencing elevated heart rate, are the tactics of a rational and safe therapy.
