Marital status and household income did not appear to have a significant independent effect on the management of hypertension. Again, the differences seen between urban residents and rural residents could be fully explained by the type of insurance coverage.

Vascular changes in the fundus reflect hypertensive retinopathy and arteriosclerotic retinopathy Renal involvement: Stroke or transient ischemic attack TIA Complications of hypertension to vascular disease probably involve three interrelated processes: These three interrelated processes are probably responsible for the arteriolar and arterial sclerosis that is the usual consequence of longstanding hypertension.

Large vessels such as the aorta may be directly affected and be at risk for aneurysms and dissection. Braunwald E, Heart disease6th ed. Are hypertensive patients at an increased risk for perioperative cardiac morbidity?

Hypertensive patients are at increased risk for coronary artery disease, silent myocardial ischemia, CHF, and stroke. However, whether preoperative hypertension is predictive of perioperative major cardiac morbidity remains controversial.

Some investigators have shown that patients with untreated, poorly controlled, or labile preoperative hypertension are at increased risk for perioperative BP lability, dysrhythmias, myocardial ischemia, and transient neurologic complications.

Some suggested that preoperative hypertension predicted perioperative myocardial infarction. However, Goldman and Caldera demonstrated that mild-to-moderate hypertension did not increase the risk of major morbid events. Instead, preoperative hypertension may predict several intermediates of outcome, such as BP lability and myocardial ischemia.

The controversy may be due to the wide variability in the hypertensive population. Hypertension may affect perioperative morbidity through the extent of end-organ damage and not the manifestation of the disease itself.

LVH, which signifies longstanding poorly controlled hypertension, can increase the risk of myocardial ischemia from imbalances of myocardial oxygen supply and demand regardless of the presence or absence of coronary artery disease.

Isolated systolic hypertension systolic BP greater than mm Hg and diastolic BP less than 90 mm Hg has been identified as a risk factor for cardiovascular complications in the general population and treatment reduces the future risk of stroke.

Predictors of postoperative myocardial ischemia in patient undergoing noncardiac surgery.

Are hypertensive patients at increased risk for perioperative cerebral and renal complications? Hypertensive patients are at increased risk for perioperative cerebrovascular accidents CVAs and acute renal failure. Most anesthetic agents produce a dose-related depression of myocardial contractility with a fall in cardiac output and a decreased blood flow to brain and kidneys.

Because autoregulation may be impaired in these patients, there is a greater susceptibility of the brain and kidney to sudden changes in pressure. In hypertensive patients, autoregulation of cerebral blood flow is reset to a higher range than normal, and although it protects the brain against sudden increases in pressure, it makes it more vulnerable to hypotension.

Thus, when BP is lowered acutely, hypertensive patients will show signs of cerebral ischemia at a higher level of BP than normotensive patients.Case Studies in Primary Hypertension Results from the HOT trial revealed that a DBP of mm Hg in nondiabetic hypertensive patients result-ed in the lowest incidence of major cardiovascular events.

The association between uric acid (UA) on one side and systemic hypertension (Htn), dyslipidemia, glucose intolerance, overweight, fatty liver, renal disease and cardiovascular disease (CVD) on the other side is well recognized. CHEST Annual Meeting Abstracts.
