The major risk with oral agents is ischemic symptoms (e.g., angina pectoris, myocardial infarction, or stroke) due to an excessive and uncontrolled hypotensive response. [23] Thus, their use should generally be avoided in the treatment of hypertensive crises if more controllable drugs are available. [citation needed]
Some risks associated with stroke are hypertension (high blood pressure), atrial fibrillation (an irregular heartbeat) and smoking, according to the US Centers for Disease Control and Prevention.
CT scan of two lacunar infarctions. Moments after an ischemic stroke, lesions are established that can be detected. Hypertension is the leading cause of strokes and studies show that it increases the risk of a stroke by 220% [17] [18] and stroke is the leading cause of long-term disability. [19] High blood pressure weakens arteries (small ...
Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension. It is estimated that for every 20 mm Hg systolic or 10 mm Hg diastolic increase in blood pressures above 115/75 mm Hg, the mortality rate for both ischemic heart disease, cancer and stroke doubles.

The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis. [5]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
The incidence of stroke rises progressively with increasing blood pressure levels, particularly systolic blood pressure in individuals >65 years. Treatment of hypertension convincingly decreases the incidence of both ischemic and hemorrhagic strokes. [41] Hypertension is also associated with impaired cognition in an aging population.
These changes are most prominent in the kidney and can lead to ischemia and acute kidney failure. In the brain, a small cavity called a lacune is an ischemic cavity that can arise due to brain necrosis, due to arteriolosclerosis. [15] [16] Cause. It can be caused by chronic benign (essential) hypertension [17] malignant hypertension. [4] [18]
