Сравнительная оценка эффективности ивабрадина и атенолола у больных гипертрофической кардиомиопатией

In 35 patients with hypertrophic cardiomyopathy, the effects of ivabradine (15 mg/d) and atenolol (50 mg/d) on physical stress tolerability (veloergometry test results) were investigated. Ivabradine and atenolol therapy was associated with increased test time: +1,5 minutes (p<0,01) and +2,4 minutes (p<0,01), respectively. Both medications prevented angina attacks and paradoxical blood pressure drop during the physical stress test.
