Multi-Vessel Coronary Artery Disease among Young Patients in Pakistan

Abstract

An article by Ibrahim et al. reports a concerningly high prevalence of multivessel coronary artery disease (MVD) among young patients presenting with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI) at a tertiary cardiac center in Multan, Pakistan. Nearly 46% (171 patients) of individuals with premature coronary artery disease (PCAD) had angiographically significant multivessel disease, indicating that almost every second young patient presented with extensive coronary involvement rather than isolated culprit-vessel disease [1]. This finding challenges the traditional perception that premature coronary artery disease is predominantly characterized by single-vessel thrombosis in otherwise healthy young adults. Instead, the study suggests that many young Pakistani patients presenting with STEMI already have diffuse and advanced atherosclerotic disease at the time of their first clinical presentation [1]. The reported prevalence of multivessel disease is particularly noteworthy when viewed within an international context. Studies from different regions have demonstrated that young patients with acute coronary syndrome may also exhibit multivessel coronary disease; however, reported frequencies vary substantially depending on population characteristics, cardiovascular risk profiles, preventive healthcare systems, and angiographic definitions used [2,3]. The prevalence of 46.2% reported in the present study lies at the higher end of the published literature and supports growing evidence that South Asian populations experience premature coronary artery disease with a greater burden of metabolic risk factors than many Western populations [4–6]. Therefore, direct comparison with international studies should be interpreted cautiously. STEMI occurring in young Pakistani patients should not simply be considered a younger manifestation of coronary artery disease seen in older Western populations; rather, it may represent a distinct phenotype influenced by genetic susceptibility, adverse early-life exposures, rapid urbanization, increasing diabetes prevalence, smoking, sedentary lifestyles, and changing dietary behaviors [4–6]. One of the major contributions of this study is that it highlights the discrepancy between the substantial burden of coronary artery disease and the limited predictive value of conventional cardiovascular risk assessment alone. Although obesity and diabetes mellitus were highly prevalent among study participants, neither variable reached statistical significance, most likely because of the relatively small sample size [1]. Nevertheless, from a public health perspective, these observations remain clinically important. In Pakistan, cardiometabolic disorders frequently develop at younger ages, remain underdiagnosed for prolonged periods, and are compounded by limited access to preventive healthcare services [7-12]. Consequently, the absence of statistically significant associations in a single-center study should not be interpreted as evidence that these risk factors are unimportant. Future multicenter investigations should incorporate a broader range of cardiovascular determinants, including comprehensive lipid profiles, lipoprotein(a), waist circumference, inflammatory biomarkers, socioeconomic indicators, dietary patterns, and detailed family history to better characterize the determinants of premature multivessel coronary disease. The findings also underscore the profound impact of ongoing lifestyle and nutritional transitions occurring throughout Pakistan. Historically, traditional home-prepared meals, despite variable fat and salt content, were generally consumed within structured family settings with relatively consistent meal timing and portion control. However, rapid urbanization, dual-income households, demanding work schedules, hostel living, food delivery services, and aggressive marketing of processed foods have collectively shifted dietary behaviors toward frequent consumption of fast foods, fried snacks, sugar-sweetened beverages, late-night meals, and regular restaurant dining [8–10]. These societal changes represent more than a cultural transition; they have fundamentally altered the cardiovascular risk environment of the country. Dietary patterns characterized by refined carbohydrates, industrial trans fats, excessive sodium intake, and oversized portions contribute directly to central obesity, insulin resistance, dyslipidemia, hypertension, and chronic systemic inflammation. When combined with physical inactivity and tobacco use, these exposures may accelerate atherosclerotic progression well before middle age [5,6,11]. Several Pakistani studies have consistently demonstrated frequent fast-food consumption, irregular meal patterns during working hours, sedentary lifestyles, overweight, obesity, and clustering of cardiovascular risk factors among young adults [8–10]. These observations provide a plausible explanation for why premature coronary artery disease appears to be particularly aggressive within the Pakistani population. In contrast, many high-income countries have implemented widespread lipid screening, smoking cessation initiatives, exercise promotion, and preventive healthcare strategies that facilitate earlier detection and risk-factor modification before patients present with acute STEMI [11,12]. Unfortunately, many young Pakistani patients first enter the healthcare system only after developing an acute coronary syndrome, at which point coronary angiography reveals extensive disease that has progressed silently over many years. These findings reinforce that successful culprit-vessel PCI represents only one component of comprehensive management for young patients with STEMI. Once premature multivessel coronary disease has been identified, aggressive secondary prevention should immediately be instituted. This includes high-intensity lipid-lowering therapy, strict control of diabetes and hypertension, smoking cessation, structured cardiac rehabilitation, weight management, dietary modification, and individualized counseling tailored to the Pakistani population [1,5,12]. Cardiologists should routinely obtain detailed dietary histories, specifically assessing fast-food consumption, intake of sugar-sweetened and energy drinks, late-night eating habits, workplace dietary practices, and restaurant dining frequency rather than relying solely on generic recommendations regarding healthy eating. Preventive cardiology remains underdeveloped in Pakistan and requires expansion beyond hospital-based care into schools, colleges, universities, workplaces, media campaigns, mosques, and community settings. Public health initiatives should promote culturally acceptable alternatives to unhealthy dietary practices while encouraging healthier traditional diets, reduced consumption of processed foods, trans fats, and excessive sodium, alongside increased physical activity. The findings emphasize that premature coronary artery disease in Pakistan should not be viewed solely as an interventional cardiology challenge but rather as a broader societal and public health problem. The high prevalence of multivessel coronary artery disease among young Pakistani patients with STEMI should prompt cardiologists, primary care physicians, public health professionals, policymakers, and families to reconsider how early cardiovascular risk begins and how rapidly evolving dietary and lifestyle patterns accelerate progression toward irreversible coronary artery disease [1,7]. Future Pakistani research should examine differences in dietary behaviors, fast-food consumption, restaurant dining patterns, and urban versus rural lifestyles, while correlating these exposures with angiographic disease burden and long-term cardiovascular outcomes. Ultimately, the most appropriate interpretation of this study is that prevention must begin early, be implemented aggressively, and specifically address the changing dietary and lifestyle patterns that are driving the growing burden of premature coronary artery disease in Pakistan.
