Women Undergoing Coronary Angiography for Myocardial Infarction or Who Present With Multivessel Disease Have a Poorer Prognosis Than Men

Persistent Symptoms and Health Needs of Women and Men With Non-Obstructed Coronary Arteries in the Years Following Coronary Angiography

Background: The prognosis of women and men with persistent anginal complaints and non-obstructed coronary arteries is impaired as compared with asymptomatic women and men. The increased healthcare burden in the hospital due to repeated coronary angiography in these women and men has been documented, yet little is known about the percentage of women and men who remain symptomatic and under care of the general practitioner in the years following a coronary angiographic outcome of non-obstructed coronary arteries. Methods: From the Utrecht Coronary Biobank study, including individuals who underwent a coronary angiography from 2011 to 2015 (N = 2,546, 27% women), we selected women and men with non-obstructed coronary arteries (N = 687, 39% women). This population was linked to the Julius General Practitioners Network (JGPN); a database with routine care data of general practitioners. For every individual with non-obstructed coronary arteries, we selected an asymptomatic non-referred age-, sex-, and general practitioner-matched individual from the JGPN. We compared the healthcare consumption of men and women with non-obstructed coronary arteries to these matched individuals. The McNemar's test was used for pairwise comparison, and sex differences were assessed using stratified analyses. Results: The prevalence of non-obstructed coronary arteries was higher in women as compared with men (39 vs. 23%). During a median follow-up of 7 years [IQR 6.4-8.0], 89% of the individuals with non-obstructed coronary arteries (91% women and 87% men) visited their general practitioner for one or more cardiovascular consultations. This was compared to 34% of the matched individuals (89 vs. 34%, p < 0.001). The consultations were most often for angina (equivalents) (57 vs. 11%, p < 0.001) and heart failure (10 vs. 2%, p = 0.015). In addition, they more often consulted the general practitioner for psychosocial complaints (31 vs. 15%, p = 0.005). Findings were similar for women and men. Conclusions: A coronary angiographic outcome of non-obstructed coronary arteries is more common in women than in men. In the years following the coronary angiography, the majority of the population remains symptomatic. Both women and men with non-obstructed coronary arteries had higher health needs for angina, heart failure, and psychosocial complaints than matched asymptomatic individuals.

Comparative assessment of clinical profile and outcomes after primary percutaneous coronary intervention in young patients with single vs multivessel disease

BACKGROUND

Even though percutaneous coronary intervention (PCI) improved the survival of patients with acute myocardial infarction, still multivessel coronary artery disease remains an important factor burdening prognosis and it is being associated with a worse prognosis compared to single-vessel disease (SVD).

AIM

To compare the clinical profile and outcomes after the primary PCI in young patients with SVD vs multivessel disease (MVD).

METHODS

The retrospective cohort of patients were divided into two groups: SVD and MVD group. The study population consisted of both male and female young (≤ 45 years) patients presented with ST-elevation myocardial infarction (STEMI) at the National Institute of Cardiovascular Disease, Karachi, Pakistan and undergone primary PCI from 1^st July 2017 to 31^st March 2018. Pre and post-procedure management of the patients was as per the guidelines and institutional protocols.

RESULTS

A total of 571 patients with STEMI, ≤ 45 years were stratified into two groups by the number of vessels involved, 342 (59.9%) with SVD and 229 (40.1%) with MVD. The average age of these patients was 39.04 ± 4.86 years. A lower prevalence of hypertension and diabetes was observed in SVD as compare to MVD group (25.1% vs 38%, P < 0.01; 11.7% vs 27.5%, P < 0.001) respectively. While, smoking was more prevalent among the SVD group as compare to MVD group (36.3% vs 28.4%, P = 0.05). The high-C Lesion was observed in a significantly higher number of younger patients with MVD as compared to SVD group (48.8% vs 39.2%, P = 0.021). Post-procedure thrombolysis in myocardial infarction flow grade was found to be not associated with the number of diseased vessels with a P value of 0.426 and thrombolysis in myocardial infarction flow grade III was observed in 98% vs 96.5% of the patients is SVD vs MVD group.

CONCLUSION

The MVD comprised of around 40% of the young patients presented with STEMI. Also, this study shows that diabetes and hypertension have a certain role in the pathogenesis of multivessel diseases, therefore, preventive measures for diabetes and hypertension can be effective strategies in reducing the burden of premature STEMI.

Challenges in Sex- and Gender-Centered Prevention and Management of Cardiovascular Disease: Implications of Genetic, Metabolic, and Environmental Paths

The recognition of cardiovascular disease (CVD) as a "male" privilege has been a commonly held concept. However, emerging data describe another reality. Heterogeneities have been convincingly demonstrated regarding CVD manifestations, risk factor burden, and prognosis between males and females. The aim of the present narrative review was to highlight sex- and gender-related discrepancies in primary and secondary CVD prevention, underscoring plausible underlying mechanisms. Manifestation of CVD in women is characterized by atypical symptoms/signs and inadequately studied pathophysiology features challenging accurate diagnosis and effective treatment. Regarding CVD risk assessment, the burden and effect size of conventional, novel, and female-specific risk factors needs better clarification. Hitherto outcomes are nonconsistent, while most importantly, the interpretation of the attendant metabolic paths remains a challenge; the interactions among genetic, metabolic, and environmental factors are of high complexity regulated by genomic and nongenomic sex hormones effects. To deal with these key points, the National Institutes of Health currently calls upon investigators to provide a sex- and gender-specific reporting in all health research hypotheses. The implementation of high-quality studies addressing these issues is an imperative need to maximize cost-effectiveness in prevention and management strategies.
