Abstract:

BACKGROUND: Limited data are available to assess whether access to and quality of cardiovascular disease (CVD) care are comparable among men and women in India. We analyzed data from the American College of Cardiology's PINNACLE (Practice Innovation and Clinical Excellence) India Quality Improvement Program (PIQIP) to evaluate gender disparities in CVD care delivery. METHODS AND RESULTS: Between 2011 and 2015, we collected data on performance measures for patients with coronary artery disease (CAD) (n = 14,010), heart failure (HF) (n = 11,965) and atrial fibrillation (AF) (n = 496) in PIQIP, among 17 participating practices. The total number of women was 31,796 (32.0%). Women had fewer total encounters compared to men during the study interval (mean number of encounters = 2.59 vs. 2.82 for women and men, respectively, p = 0.001). Women were significantly younger (48.9years vs. 51.5years, p = 0.01), but had a higher co-morbidity burden compared to men - hypertension (62.0% vs. 45.6%, p = 0.01), diabetes (39.4% vs. 35%, p = 0.01), and hyperlipidemia (3.7% vs. 3.1%, p = 0.19). On the contrary, the guideline-directed medication prescriptions were strikingly lower in women with CAD compared to men - aspirin (38% vs. 50.4%, p = 0.001), aspirin or thienopyridine combination (46.9% vs. 57.2%, p = 0.001), and beta-blockers (36.8% vs. 47.8%, p = 0.001). Similarly, among women with ejection fraction = 40%, the use of guideline-directed medical therapy was significantly lower compared to men for beta-blockers (30.8% vs. 37.0%, p = 0.001), angiotensin-converting enzyme inhibitors (ACE-i) or angiotensin receptor blockers (ARBs) (29.3% vs. 34.9%, p = 0.001), and beta-blockers/ACE-i or ARBs (24.6% vs. 31.0%, p = 0.001). Among patients with atrial fibrillation and CHADS2 score = 2, more women were on oral anticoagulation (19.6% vs. 14.6%, p = 0.34), although this was not significantly different, and the overall number of patients with atrial fibrillation was low. CONCLUSIONS: Despite a significantly higher co-morbidity burden in women, we found fewer women receiving guideline-directed medical therapy for CVD compared with men. If such disparities are confirmed in the larger Indian population, it is important to find potential causes for, and seek solutions to narrow this gap.
