Plaque build-up, also known as atherosclerosis, lies at the heart of many cardiovascular diseases, including coronary artery disease, peripheral artery disease, and stroke. This article delves into the intricacies of plaque formation, progression, and its implications for cardiovascular health. Atherosclerosis is a complex inflammatory process characterized by the gradual accumulation of plaque within the walls of arteries. The primary components of plaque include cholesterol, fatty substances, cellular debris, and inflammatory cells, which infiltrate the arterial intima and initiate the formation of atherosclerotic lesions. The initial stage of plaque build-up involves the dysfunction of endothelial cells lining the arterial wall, which allows for the infiltration of low-density lipoprotein cholesterol into the vessel wall. cholesterol undergoes oxidation and becomes trapped within the arterial intima, triggering an inflammatory response and recruitment of monocytes and macrophages to the site of injury. Macrophages engulf oxidized particles, forming foam cells that contribute to the formation of fatty streaks within the arterial wall [1,2].
Over time, smooth muscle cells migrate from the media to the intima and proliferate, producing extracellular matrix components such as collagen and proteoglycans that contribute to plaque stability. As the atherosclerotic lesion progresses, it undergoes remodelling, with the accumulation of lipidrich necrotic cores, calcification, and fibrous cap formation. Vulnerable plaques, characterized by a thin fibrous cap and a large lipid core, are prone to rupture, leading to thrombus formation and acute cardiovascular events such as myocardial infarction or stroke. Several risk factors contribute to the development and progression of plaque build-up, including hypertension, dyslipidaemia, diabetes, smoking, obesity, and a sedentary lifestyle. These risk factors promote endothelial dysfunction, dyslipidaemia, inflammation, oxidative stress, and thrombosis, accelerating the atherosclerotic process and increasing the likelihood of plaque rupture. Diagnosis of plaque build-up typically involves a combination of clinical evaluation, imaging studies, and laboratory tests to assess cardiovascular risk and evaluate the extent of atherosclerosis. Non-invasive imaging modalities such as carotid ultrasound, coronary calcium scoring, and coronary angiography enable visualization of atherosclerotic plaques and assessment of coronary artery disease burden. Invasive procedures such as coronary angiography and intravascular ultrasound provide detailed information about plaque morphology, composition, and severity, guiding treatment decisions and risk stratification in patients with symptomatic or high-risk coronary artery disease. Management of plaque build-up focuses on reducing cardiovascular risk factors, stabilizing atherosclerotic plaques, and preventing acute cardiovascular events. Lifestyle modifications, including dietary changes, regular exercise, smoking cessation, and weight management, form the cornerstone of primary and secondary prevention strategies. Pharmacological therapy aims to target underlying pathophysiological processes contributing to plaque formation and progression. Statins, antiplatelet agents, antihypertensive medications, and glucose-lowering agents are among the medications used to optimize lipid profiles, inhibit platelet aggregation, control blood pressure, and improve glycemic control in patients with atherosclerosis. In addition to medical therapy, invasive interventions such as percutaneous coronary intervention or coronary artery bypass grafting may be indicated for patients with obstructive coronary artery disease or high-risk plaque features involves the placement of stents to widen narrowed or blocked arteries, while entails surgical revascularization using grafts to bypass obstructive lesions [3,4].
Emerging therapies such as lipid-lowering agents, antiinflammatory medications, and novel plaque stabilization strategies hold promise for further improving outcomes in patients with atherosclerosis. By targeting specific pathways involved in plaque formation and progression, these therapies offer potential alternatives for patients with refractory disease or residual cardiovascular risk despite optimal medical therapy. In conclusion, plaque build-up represents a major contributor to cardiovascular morbidity and mortality worldwide, underscoring the importance of early detection, risk factor modification, and aggressive management strategies. By understanding the pathophysiology of atherosclerosis and implementing comprehensive approaches to plaque stabilization and prevention, clinicians can mitigate the burden of cardiovascular disease and improve outcomes for affected individuals.
