- Cardiovascular disease risk factors include modifiable and non-modifiable elements. This occurs because genetic predisposition and age cannot be changed but create increased susceptibility. For example, family history of heart disease increases individual risk through inherited genetic factors. Additionally, smoking damages arterial walls and reduces oxygen delivery to heart muscle. High blood pressure causes arterial stress and atherosclerosis development. Consequently, obesity leads to increased cardiac workload and metabolic dysfunction.
- Protective factors help to prevent cardiovascular disease through lifestyle modifications. This happens when regular physical activity strengthens heart muscle and improves circulation efficiency. For instance, aerobic exercise reduces blood pressure and increases HDL cholesterol levels. Healthy diet patterns provide essential nutrients while limiting saturated fats and sodium intake. Therefore, Mediterranean diets rich in omega-3 fatty acids support cardiovascular health. Furthermore, avoiding tobacco use prevents arterial damage and maintains optimal blood flow. The reason for this is protective behaviours counteract the biological processes that lead to cardiovascular disease development.
