As the left ventricle becomes unable to compensate for an acute rise in systemic vascular resistance, left ventricular failure and pulmonary edema or myocardial ischemia may occur. Cerebral autoregulation is the ability of the blood vessels in the brain to maintain a constant blood flow. Armenian Health Network, Health.

Other end-organ damage can include acute kidney failure or insufficiency, retinopathyeclampsiaand microangiopathic hemolytic anemia. Men are more commonly affected by hypertensive crises than women. Coronary perfusion pressures are decreased by these factors, which also increase myocardial oxygen consumption, possibly leading to left ventricular hypertrophy.
People with hypertensive crises often have chest pain as a result of this mismatch and may suffer from left ventricular dysfunction. Ischemia occurs as hipegtensiva result, prompting further release of vasoactive substances.
Hypertensive crises must be carefully distinguished to avoid risks as they differ in managements. The cardiovascular risk of these patients is higher than that do not suffer hypertensive crisis. Severe hypertension is a serious and potentially life-threatening medical condition.
