Subject : Exploring the Cardiovascular Continuum: Insights from Practicing Cardiologists (CARDIO-INSIGHTS)

Cardiovascular diseases (CVDs) remain the leading cause of morbidity and mortality worldwide, presenting a significant challenge to healthcare systems and necessitating continuous advancements in clinical practice and patient management. The cardiovascular continuum—a conceptual framework describing the progression from risk factors like hypertension and dyslipidemia to advanced conditions such as heart failure and stroke—provides a comprehensive understanding of the interconnected stages of cardiovascular health and disease. Practicing cardiologists, as the primary healthcare providers for these conditions, play a crucial role in managing this continuum and implementing evidence-based interventions.

Cardiovascular diseases are the number one cause of death globally, accounting for an estimated 17.9 million lives each year, which represents 31% of all global deaths. The burden of CVD is escalating due to aging populations, urbanization, and the global rise in risk factors such as obesity, diabetes, and hypertension. Low- and middle-income countries disproportionately suffer from cardiovascular diseases, with over 75% of CVD deaths occurring in these regions.

In India, CVDs are also the leading cause of death, responsible for 28% of all deaths. The prevalence of CVDs in India is on a sharp rise, attributed to lifestyle changes, increased urbanization, and a growing prevalence of risk factors such as hypertension, diabetes, smoking, and sedentary lifestyle. Recent trends indicate a significant burden among the younger population, with increasing cases of myocardial infarction and stroke among individuals below 50 years of age. This alarming trend underscores the critical need for targeted interventions and public health strategies to manage and mitigate the impact of CVDs in India.

Cardiovascular diseases result from a complex interplay of genetic, environmental, and lifestyle factors that lead to the gradual deterioration of cardiovascular health. The pathophysiology involves endothelial dysfunction, inflammation, and plaque formation in the arterial walls, leading to atherosclerosis. Over time, these plaques can rupture, causing thrombosis and leading to acute events such as myocardial infarction and stroke. Hypertension and dyslipidemia are key contributors to this process, exacerbating vascular damage and promoting the progression of heart failure and arrhythmias. The complications of CVDs are severe and multifaceted, including heart failure, stroke, peripheral artery disease, and sudden cardiac death4. These complications significantly reduce the quality of life and increase healthcare costs. Heart failure leads to frequent hospitalizations and a high mortality rate, while stroke can result in long-term disability and cognitive impairment. Peripheral artery disease causes pain and mobility issues, and arrhythmias increase the risk of stroke and sudden death.

Current pharmacotherapy for CVDs includes a wide range of medications aimed at managing risk factors and preventing complications. These include antihypertensives (ACE inhibitors, beta-blockers, calcium channel blockers), statins for dyslipidemia, antiplatelet agents (aspirin, clopidogrel), and anticoagulants for patients with atrial fibrillation. Guidelines from national and international bodies such as the American Heart Association (AHA), European Society of Cardiology (ESC), and Indian Heart Association (IHA) provide evidence-based recommendations for the use of these medications.

Several landmark clinical trials have shaped the current pharmacotherapy landscape for CVDs. The HOPE trial demonstrated the benefits of ACE inhibitors in reducing cardiovascular events. The JUPITER trial highlighted the role of statins in primary prevention, and the COMPASS trial showed the efficacy of rivaroxaban in combination with aspirin in reducing major cardiovascular events in patients with stable atherosclerosis.
