Study Notes
Cardiovascular Disease and Hypertension: Key Points
- Risk factors for hypertension include positive family history, male gender, advanced age, black race, obesity, high sodium intake, low potassium, calcium, and magnesium intake, diabetes, labile blood pressure, smoking, and heavy alcohol consumption.
- Primary hypertension is a result of complex interactions of genetics and the environment mediated by neurohumoral effects.
- The pathogenesis of primary hypertension includes overactivity of the sympathetic nervous system (SNS), renin-angiotensin-aldosterone system (RAAS), and other neurohumoral mediators, inflammation, insulin resistance, endothelial dysfunction, and obesity-related hormonal changes.
- Clinical manifestations of hypertension result from damage to organs and tissues outside the vascular system, including heart disease, renal disease, CNS problems, and retinal changes.
- Pharmacological management of hypertension includes diuretics, adrenergic blockers, calcium channel blockers, ACE inhibitors, and Ang II receptor blockers, while nonpharmacologic methods include smoking cessation, dietary modifications, and exercise.
- Orthostatic hypotension is a drop in blood pressure upon standing, caused by altered compensatory vasoconstriction response due to vasodilation and blood pooling in muscle vasculature.
- Clinical manifestations of orthostatic hypotension include fainting and may lead to falls and significant injury.
- An aneurysm is a localized dilation of a vessel wall, particularly susceptible in the aorta.
- A thrombus is a clot attached to a vascular wall, while an embolus is a mobile aggregate occluding the vasculature, sourced from various substances including thrombi, air, amniotic fluid, bacteria, fat, and foreign matter.
- The most common sources of arterial thrombotic emboli from the heart are mitral and aortic valvular disease and atrial fibrillation, affecting lower extremities, brain, and heart.
- Vasospastic disorders include thromboangiitis obliterans and Raynaud disease, involving arterioles of the extremities.
- Atherosclerosis, an inflammatory disease, is the leading cause of coronary artery and cerebrovascular disease, resulting in plaque formation, rupture, thrombosis, vasoconstriction, and inadequate perfusion of distal tissues.
