Primary (or essential) hypertension represents between 85% and 95% of human cases and has an unidentified cause. In contrast, secondary hypertension is caused by identifiable underlying conditions, including renal artery stenosis, pheochromocytoma, adrenal adenoma, or single-gene mutations.
Summarize the pathophysiology of essential hypertension and its pathological sequelae on organ systems throughout the body. Review the various treatment options for treating essential hypertension, both pharmacological as well as lifestyle modification strategies.
The pathophysiology of hypertension involves the impairment of renal pressure natriuresis, the feedback system in which high blood pressure induces an increase in sodium and water excretion by the kidney that leads to a reduction of the blood pressure.
Factors that play an important role in the pathogenesis of hypertension include the aging process, genetics, activation of neurohormonal systems such as the sympathetic nervous system and...
Pathophysiology. Hypertension is a chronic elevation of blood pressure that, in the long-term, causes end-organ damage and results in increased morbidity and mortality. Blood pressure is the product of cardiac output and systemic vascular resistance.
The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary.
In patients with secondary hypertension, including cancer patients with new onset or worsening hypertension, the pathophysiology of hypertension can be a result of one or more of the aforementioned mechanism (Table 1). Table 1. Summary of mechanisms by which chemotherapy raise blood pressure. Prakash Nepali MBBS, ...
