The pathophysiological factors influencing the incidence and manifestations of cardiovascular diseases, particularly hypertension and atherosclerosis, are complex and multifactorial, affecting individuals across all stages of life. Understanding these factors is essential for developing effective prevention and treatment strategies and for educating communities to mitigate the burden of these diseases.

Hypertension, or high blood pressure, is a prevalent chronic condition that contributes significantly to cardiovascular morbidity and mortality worldwide. Its development involves a combination of genetic, environmental, and physiological factors. Elevated blood pressure results from alterations in vascular tone and structure, increased peripheral resistance, and dysregulation of hormonal systems such as the renin-angiotensin-aldosterone system (Rahman et al., 2014). Essential hypertension, the most common form, often arises from a combination of genetic predisposition and lifestyle factors such as high sodium intake, sedentary behavior, obesity, and excessive alcohol consumption (Carretero & Oparil, 2000).

Atherosclerosis, a chronic inflammatory process affecting arterial walls, often underlies many cardiovascular diseases, including coronary artery disease and stroke. Its development is driven by endothelial dysfunction, lipid accumulation, and immune cell infiltration. Risk factors such as hypercholesterolemia, smoking, hypertension, and diabetes mellitus accelerate plaque formation and instability (Libby, 2013). Endothelial cells lining blood vessels become increasingly permeable under stress, facilitating lipid infiltration, particularly low-density lipoprotein (LDL) cholesterol, which undergoes oxidation and triggers inflammatory responses, further damaging arterial walls.

The manifestations of these diseases vary across the lifespan, influenced by age-related physiological changes and cumulative exposure to risk factors. In childhood and adolescence, early signs of endothelial dysfunction and subclinical atherosclerosis may be present, especially among those with familial predispositions or unmanaged risk factors. During adulthood, the risk manifests as clinical hypertension, angina, or stroke. In older populations, structural arterial changes, such as arterial stiffening and calcification, exacerbate disease severity and complicate management (Lakatta & Levy, 2003).

The key risk factors for these conditions include lifestyle choices and genetic predispositions. High salt intake, obesity, physical inactivity, smoking, and poor diet increase the likelihood of hypertension and atherosclerosis. Genetic factors also play a role, with familial hypercholesterolemia and inherited hypertension syndromes illustrating the hereditary component (Nordestgaard et al., 2013). Emerging research highlights the importance of epigenetic modifications and microbiome influences on disease development, emphasizing the need for integrated prevention strategies.

Possible consequences of unmanaged hypertension and atherosclerosis are severe, including myocardial infarction, stroke, heart failure, and renal failure, which can significantly impair quality of life and increase mortality rates. Chronic hypertension can lead to hypertensive nephropathy and heart hypertrophy, further escalating cardiovascular risk. Atherosclerotic plaque rupture may cause thrombotic events leading to acute coronary syndromes. These outcomes underscore the importance of early detection, lifestyle modifications, and adherence to pharmacological treatments.

Prevention strategies focus on lifestyle interventions such as adopting a diet rich in fruits, vegetables, and whole grains, reducing salt intake, engaging in regular physical activity, maintaining a healthy weight, limiting alcohol consumption, and avoiding tobacco use. Pharmacological treatments include antihypertensives like ACE inhibitors and beta-blockers, and statins for lipid management. Regular screening and community education are vital for early detection and risk reduction, especially in high-risk populations (Whelton et al., 2018).
