Hypertension complications

Another study (84), which enrolled men and women between the ages of 21—55 who had mild hypertension and no recognizable cardiovascular risk factors, showed no significant differences in mortaUty between dmg- and placebo-treated patients. Significant reductions in hypertensive complications were noted, but atherosclerotic complications were not reduced. 

Renal blood flow and glomerular filtration are not decreased, although renal resistance is diminished. Like a-methyldopa, it is a useful agent for hypertension complicated by renal disease. Plasma renin activity is reduced by clonidine, presumably as a result of a centrally mediated decrease in sympathetic stimulation of the juxtaglomerular cells of the kidney. 

The serious adverse effects associated with bevacizumab include GI perforation, hemorrhage, hypertension, complications in wound healing, nephritic syndrome, congestive heart failure and arterial thromboembolic events. Patients receiving bevacizumab commonly experience pain, asthenia, headache, abdominal pain, nausea, vomiting, anorexia, upper respiratory infection and exfoliative dermatitis.

This a2-agonist diminishes central adrenergic outflow. Clonidine [KLOE ni deen] (see p. 67) is used primarily for the treatment of mild to moderate hypertension that has not responded adequately to treatment with diuretics alone. Clonidine does not decrease renal blood flow or glomerular filtration and therefore is useful in the treatment of hypertension complicated by renal disease. Clonidine is...

Hypokalemia. Hypokalemia associated with thia2ide diuretic therapy has been knpHcated in the increased incidence of cardiac arrhythmias and sudden death (82). Several large clinical trials have been conducted in which the effects of antihypertensive dmg therapy on the incidence of cardiovascular complications were studied. The antihypertensive regimen included diuretic therapy as the first dmg in a stepped care (SC) approach to lowering the blood pressure of hypertensive patients. 

Ms. tbnes is admitted to the emergency department in hypertensive crids. Nitroprusdde therapy is begun, and you are asked to monitor this patient. Discuss important pomts that the nurse should keep in mind when adminidering this drug. Identify methods you would use to monitor the patient and prevent complications. 

The active drug and metabolites can be detected from the urine by thin-layer chromatography, gas-liquid chromatography, or gas chromatography-mass spectrometry. However, assays are available only at specialized centers. Treatment of acute intoxication with mescaline is virtually identical to the treatment outlined for LSD intoxication. DOM-induced vasospasm responds well to intra-arterial tolazohne or sodium nitroprusside. Major life-threatening complications of hallucinogenic amphetamine derivatives include hyperthermia, hypertension, convulsions, cardiovascular collapse, and self-inflicted trauma. 

Inexperienced users or individuals who are exposed to the drug unexpectedly (e.g., who unknowingly consume PCP-adulterated cannabis) may develop severe anxiety and panic because of the intensity and variety of symptoms. Perceptual distortions have sometimes led to extremely violent behavior, accidents, or self-damaging acts. An especially high risk of violent behavior has been reported in acutely intoxicated PCP users who have a history of psychiatric problems. Intoxication with doses in excess of 150 mg may lead to convulsions, coma, and death from respiratory arrest. Other complications include hypertensive crisis, intracerebral hemorrhage, and renal failure (Table 6-5). 

Like dyslipidemia, hypertension is a major, modifiable risk factor for the development of IHD and related complications. Unfortunately, awareness, treatment, and control of blood pressure are not nearly enough.30 Aggressive identification and control of hypertension is warranted in patients with IHD to minimize the risk of major adverse cardiac events. Goal blood pressure in patients with IHD is less than 140/90 mm Hg or less than 130/80 mm Hg in patients with diabetes. Because of their cardioprotective benefits, 3-blockers and ACE inhibitors (or ARBs in ACE-inhibitor-intolerant patients), either alone or in combination, are appropriate for most patients with both hypertension and IHD. 

The long-term (i.e., more than 3 months after the first event) goals of therapy are to prevent complications such as the postthrom-botic syndrome, pulmonary hypertension, and recurrent VTE. 

Pulmonary hypertension develops late in the course of COPD, usually after the development of severe hypoxemia. It is the most common cardiovascular complication of COPD and can result in cor pulmonale, or right-sided heart failure. Hypoxemia plays the primary role in the development of pulmonary hypertension by causing vasoconstriction of the pulmonary arteries and by promoting vessel wall remodeling. Destruction of the pulmonary capillary bed by emphysema further contributes by increasing the pressure required to perfuse the pulmonary vascular bed. Cor pulmonale is associated with venous stasis and thrombosis that may result in pulmonary embolism. Another important systemic effect is the progressive loss of skeletal muscle mass, which contributes to exercise limitations and declining health status. 

List the treatment goals for a patient with portal hypertension and its complications. 

O Portal hypertension is the precipitating factor for the complications of cirrhotic liver disease—ascites, spontaneous bacterial peritonitis (SBP), variceal bleeding, and hepatic encephalopathy. Lowering portal pressure can reduce the complications of cirrhosis and decrease morbidity and mortality. 

Cirrhosis is the progressive replacement of normal hepatic cells by fibrous scar tissue. This scarring is accompanied by the loss of viable hepatocytes, which are the functional cells of the liver. Progressive cirrhosis is irreversible and leads to portal hypertension that is in turn responsible for many of the complications of advanced liver disease. These consequences include (but are not limited to) spontaneous bacterial peritonitis (SBP), hepatic encephalopathy, and variceal bleeding.1...
