Causes
Atherosclerosis, a multifaceted disease, arises from a convergence of genetic predispositions and modifiable risk factors. High cholesterol levels, particularly elevated low-density lipoprotein (LDL) cholesterol, serve as primary culprits in plaque formation. Excess LDL cholesterol infiltrates arterial walls, initiating a cascade of inflammatory responses that promote plaque development. Smoking, a prevalent risk factor, accelerates atherosclerosis progression through various mechanisms. Nicotine and other harmful components in tobacco smoke damage endothelial cells, impairing their function and promoting lipid deposition.
Hypertension, a common comorbidity, exacerbates atherosclerosis by subjecting arterial walls to chronic hemodynamic stress. Elevated blood pressure strains endothelial integrity, facilitating lipid infiltration and inflammatory cell recruitment. Diabetes mellitus, characterized by impaired glucose metabolism, amplifies atherosclerosis risk through multiple pathways. Hyperglycemia induces oxidative stress and endothelial dysfunction, fostering plaque formation and arterial stiffening.
Inflammatory processes play a pivotal role in atherosclerosis pathogenesis, bridging genetic predispositions and environmental triggers. Chronic inflammation, triggered by oxidative stress, immune dysregulation, and metabolic abnormalities, perpetuates endothelial dysfunction and promotes plaque instability. Additionally, genetic factors predispose certain individuals to accelerated atherosclerosis development. Variations in genes encoding lipid metabolism enzymes, inflammatory mediators, and endothelial function regulators influence disease susceptibility and progression.
Moreover, lifestyle factors such as sedentary behavior, poor dietary choices, and excessive alcohol consumption contribute to atherosclerosis risk. Sedentary lifestyles promote dyslipidemia and insulin resistance, exacerbating metabolic derangements conducive to plaque formation. Unhealthy dietary habits, characterized by high saturated fat and low fiber intake, exacerbate dyslipidemia and systemic inflammation, fueling atherosclerosis progression. Excessive alcohol consumption, although controversial, may contribute to atherosclerosis through various mechanisms, including altered lipid metabolism and increased oxidative stress.
In summary, atherosclerosis arises from a complex interplay of genetic predispositions and modifiable risk factors encompassing dyslipidemia, smoking, hypertension, diabetes mellitus, inflammatory processes, and lifestyle habits. Understanding these multifaceted causes is pivotal in devising effective preventive and therapeutic strategies against this pervasive cardiovascular disease.

Signs and Symptoms
Atherosclerosis, often insidious in its onset, manifests through a spectrum of clinical signs and symptoms reflecting compromised blood flow to vital organs. Initially asymptomatic, the disease stealthily progresses until it culminates in life-threatening events. Common indicators of atherosclerosis include angina, intermittent claudication, and critical organ ischemia.
Angina, characterized by chest discomfort or pressure, arises from myocardial ischemia secondary to coronary artery atherosclerosis. Typically triggered by physical exertion or emotional stress, angina presents as a tightness or squeezing sensation in the chest, often radiating to the arms, neck, jaw, or back. Despite being transient, angina warrants prompt medical evaluation to assess underlying coronary artery disease severity and risk of acute coronary events.
Intermittent claudication, a hallmark of peripheral artery disease, manifests as muscle pain or cramping during physical activity, particularly in the lower extremities. Diminished blood flow to leg muscles results in inadequate oxygen delivery, precipitating discomfort that subsides with rest. Intermittent claudication imposes limitations on mobility and physical function, significantly impairing quality of life.
Critical organ ischemia represents advanced atherosclerosis complications, posing imminent threats to organ viability. Myocardial infarction, a catastrophic consequence of coronary artery atherosclerosis, occurs when plaque rupture triggers thrombotic occlusion of a coronary artery, leading to myocardial tissue necrosis. Ischemic stroke, stemming from cerebral artery atherosclerosis or embolic phenomena, manifests with focal neurological deficits such as hemiparesis, aphasia, or visual disturbances. Similarly, acute limb ischemia, precipitated by peripheral artery occlusion, presents with acute limb pain, pallor, pulselessness, and paralysis, necessitating emergent revascularization interventions to salvage limb function.
In summary, atherosclerosis presents with diverse clinical manifestations ranging from exertional chest pain and intermittent claudication to life-threatening events like myocardial infarction, stroke, and acute limb ischemia. Recognizing these signs and symptoms is crucial for timely diagnosis and intervention, mitigating the morbidity and mortality associated with advanced atherosclerosis complications.

Etiology
The etiology of atherosclerosis is multifactorial, encompassing intricate interactions between genetic predispositions, environmental factors, and systemic processes. Genetic influences exert a significant impact on atherosclerosis susceptibility and progression, with variations in genes encoding lipid metabolism enzymes, inflammatory mediators, and endothelial function regulators contributing to disease pathogenesis. Familial hypercholesterolemia, an inherited disorder characterized by elevated LDL cholesterol levels, exemplifies the genetic underpinnings of atherosclerosis, underscoring the role of genetic predispositions in lipid metabolism abnormalities.
Environmental factors play a pivotal role in shaping atherosclerosis risk profiles, with lifestyle choices exerting profound influences on disease development and progression. Tobacco smoke, laden with toxic compounds, accelerates atherosclerosis through endothelial dysfunction, oxidative stress, and enhanced inflammatory responses. High-fat diets rich in saturated fats and trans fats exacerbate dyslipidemia, fostering lipid deposition within arterial walls and promoting plaque formation. Sedentary lifestyles and physical inactivity contribute to metabolic derangements, insulin resistance, and systemic inflammation, amplifying atherosclerosis risk.
Systemic processes, including chronic inflammation and oxidative stress, fuel atherosclerosis progression by perpetuating endothelial dysfunction and promoting plaque instability. Inflammatory mediators, such as C-reactive protein and interleukins, orchestrate inflammatory responses within arterial walls, attracting circulating immune cells and promoting foam cell formation. Oxidative stress, induced by reactive oxygen species, oxidizes circulating lipids, rendering them more atherogenic and facilitating their incorporation into developing plaques.
Furthermore, metabolic disorders such as diabetes mellitus and hypertension exacerbate atherosclerosis by amplifying endothelial dysfunction, oxidative stress, and inflammatory responses. Hyperglycemia, a hallmark of diabetes mellitus, promotes endothelial injury and accelerates atherosclerosis progression through glycation of vascular proteins and activation of proinflammatory pathways. Hypertension, characterized by elevated blood pressure, subjects arterial walls to chronic hemodynamic stress, fostering endothelial dysfunction and facilitating lipid infiltration.
In summary, the etiology of atherosclerosis encompasses a complex interplay of genetic predispositions, environmental influences, and systemic processes, highlighting the multifactorial nature of this pervasive cardiovascular disease. Understanding these etiological factors is paramount in devising targeted preventive and therapeutic interventions to mitigate atherosclerosis-related morbidity and mortality.

Pathophysiology
Atherosclerosis unfolds through a multifaceted pathophysiological cascade characterized by endothelial dysfunction, lipid accumulation, inflammatory responses, and plaque formation within arterial walls. Endothelial dysfunction, triggered by various insults including hemodynamic stressors and metabolic disturbances, represents a critical initiating event in atherosclerosis pathogenesis. Impaired endothelial integrity promotes the adhesion of circulating monocytes and leukocytes to the endothelial surface, initiating an inflammatory response within arterial walls.
After endothelial dysfunction, lipids, particularly low-density lipoprotein (LDL) cholesterol, infiltrate the subendothelial space and undergo oxidative modifications, rendering them more atherogenic. Oxidized LDL cholesterol induces a robust inflammatory response, attracting monocytes to the arterial intima. Monocytes differentiate into macrophages upon entering the subendothelial space, where they engulf oxidized LDL cholesterol and transform into foam cells, hallmark features of early atherosclerotic lesions.
Accumulation of foam cells within the arterial wall triggers a cascade of events leading to plaque formation. Foam cells release proinflammatory cytokines and growth factors, perpetuating local inflammation and promoting smooth muscle cell migration from the media to the intima. Smooth muscle cells proliferate and synthesize extracellular matrix components, contributing to the formation of a fibrous cap overlaying the lipid-rich core of the developing plaque.
As the atherosclerotic lesion progresses, the fibrous cap undergoes remodeling, becoming susceptible to rupture. Plaque rupture exposes the thrombogenic lipid core to the circulating blood, precipitating thrombus formation and occlusion of the affected artery. Thrombotic occlusion results in acute ischemic events such as myocardial infarction, stroke, or acute limb ischemia, underscoring the clinical significance of advanced atherosclerosis complications.
In summary, atherosclerosis pathophysiology involves a complex interplay of endothelial dysfunction, lipid accumulation, inflammatory responses, and plaque formation within arterial walls. Understanding these pathophysiological mechanisms is crucial in elucidating disease progression and devising targeted therapeutic strategies to mitigate atherosclerosis-related morbidity and mortality.

DMS-5 Diagnosis
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DMS-5), provides a structured framework for diagnosing atherosclerosis-related conditions based on clinical criteria and diagnostic tests. Diagnosis typically involves a comprehensive assessment encompassing medical history, physical examination, and ancillary investigations to evaluate cardiovascular risk factors and assess disease severity.
Clinical evaluation begins with a detailed medical history to identify predisposing factors such as smoking, hypertension, diabetes mellitus, and dyslipidemia, which significantly contribute to atherosclerosis development. Moreover, eliciting symptoms suggestive of atherosclerosis-related complications, including angina, intermittent claudication, and critical organ ischemia, aids in establishing the diagnosis.
Physical examination aims to identify objective signs of atherosclerosis and assess cardiovascular risk. Examination of peripheral pulses, auscultation for bruits over major arteries, and evaluation of lower extremity skin perfusion may reveal signs of peripheral artery disease. Moreover, assessment of blood pressure, heart rate, and signs of heart failure or valvular dysfunction provides valuable insights into cardiovascular health.
Ancillary investigations play a pivotal role in confirming the diagnosis and assessing disease severity. Laboratory tests such as lipid profiles, fasting blood glucose, and glycated hemoglobin levels help evaluate metabolic risk factors and assess disease control in individuals with diabetes mellitus. Additionally, electrocardiography (ECG), echocardiography, stress testing, and imaging modalities such as coronary angiography, computed tomography (CT) angiography, and magnetic resonance imaging (MRI) provide valuable diagnostic information regarding coronary artery disease, myocardial ischemia, and atherosclerotic plaque burden.
Integration of clinical findings and diagnostic test results enables clinicians to establish a definitive diagnosis of atherosclerosis and its related complications according to DMS-5 criteria. Accurate diagnosis facilitates risk stratification, guides therapeutic decision-making, and enhances patient outcomes through timely intervention and management of atherosclerosis-related cardiovascular conditions.
