Introduction: Beta-blockers are recommended by the European Society of Cardiology as first-line antianginal therapy for reducing heart rate (HR) and symptoms in patients with chronic coronary syndrome, despite a lack of data showing superiority to other antianginal agents. Most patients with angina pectoris require combination therapy to manage symptoms, with a second-line agent chosen to manage the predominant cardiovascular problem. Ivabradine, a selective sinus node I channel inhibitor shown to reduce HR and protect against anginal symptoms, has previously demonstrated noninferior anti-ischaemic and antianginal efficacy to beta-blockers.

Increase in life expectancy during the second part of the 20th century is accompanied by increase in proportion of elderly and senile age population. However, despite the increase in life expectancy, the prevalence of most chronic diseases and functional impairments rises with age. Elderly and senile age is associated with the risk of cardiovascular diseases (CVD), therefore the problem of managing elderly patients with CVD becomes especially urgent.

Introduction: Heart rate (HR) reduction is an integral part of antianginal therapy, but many patients do not reach the guideline-recommended target of less than 60 bpm despite high use of beta-blockers (BB). Failure to uptitrate BB doses may be partly to blame. To explore other options for lowering HR and improving angina control, CONTROL-2 was initiated to compare the efficacy and tolerability of the combination of BBs with ivabradine versus uptitration of BBs to maximal tolerated dose, in patients with stable angina.
