Abstract

- Incidence of chronic heart failure (HF) increases with age and cardiovascular (CV) morbidity. Co-morbidities increase hospitalization and mortality in HF, and non-CV co-morbidities may lead to preventable hospitalizations. We studied the impact of co-morbidities on mortality and morbidity in Systolic Heart Failure Treatment with the If Inhibitor Ivabradine Trial, and investigated whether the impact of ivabradine was affected by co-morbidities. We analyzed the Systolic Heart Failure Treatment with the If Inhibitor Ivabradine Trialpopulation, with moderate-to-severe HF and left ventricular dysfunction (in sinus rhythm with heart rate at rest >/=70 beats/min), according to co-morbidity: chronic obstructive pulmonary disease, diabetes mellitus, anemia, stroke, impaired renal function, myocardial infarction, hypertension, and peripheral artery disease. Co-morbidity load was classed as 0, 1, 2, 3, 4+ or 1 to 2 co-morbidities, or 3+ co-morbidities. Co-morbidities were evenly distributed between the placebo and ivabradine groups. Patients with more co-morbidities were likely to be older, women, had more advanced HF, were less likely to be on beta blockers, with an even distribution on ivabradine 2.5, 5, or 7.5 mg bid and placebo at all co-morbidity loads. Number of co-morbidities was related to outcomes. Cardiovascular death or HF hospitalization events significantly increased (p <0.0001) with co-morbidity load, with the most events in patients with >3 co-morbidities for both, ivabradine and placebo. There was no interaction between co-morbidity load and the treatment effects of ivabradine. Hospitalization rate was lower at all co-morbidity loads for ivabradine. In conclusion, cardiac and noncardiac co-morbidities significantly affect CV outcomes, particularly if there are >3 co-morbidities. The effect of heart rate reduction with ivabradine is maintained at all co-morbidity loads.
