Hypertension:
Treatment
(In a Page: Signs and Symptoms)
-
Essential hypertension: Lifestyle changes are the initial interventions unless significant hypertension, end-organ damage, or diabetes is present (smoking cessation; dietary changes, e.g., DASH diet =low in sodium, rich in potassium and calcium; increased exercise)
-
Pharmacologic therapy usually begins with a diuretic or β-blocker (ACE inhibitor in diabetics)
–Diuretics are usually first-line agents, especially in CHF, diabetes, and risk of coronary artery disease
–Use ACE inhibitors in patients with CHF, MI, renal disease, and diabetes
–Use β-blockers in CAD, recent MI, angina, CHF, atrial fibrillation, migraines, hyperthyroidism
–Additional drugs may include angiotensin receptor blockers (especially in patients with cough when using ACE inhibitors), calcium channel blockers, and β-blockers
–Preferred drugs in pregnancy include methyldopa, β-blockers, and vasodilators (do not use ACE/ARBs)

Hypertension:
Treatment
(Professional Guide to Diseases (Eighth Edition))
The National Institutes of Health recommend the following approach for treating primary hypertension:
❑ First, help the patient initiate necessary lifestyle modifications, including weight reduction, moderation of alcohol intake, regular physical exercise, reduction of sodium intake, and smoking cessation.
❑ If the patient fails to achieve the desired blood pressure or make significant progress, continue lifestyle modifications and begin drug therapy.
❑ For stage 1 hypertension (systolic [SBP] blood pressure 140 to 159 mm Hg, or diastolic blood pressure [DBP] 90 to 99 mm Hg) in the absence of compelling indications (heart failure, postmyocardial infarction, high coronary disease risk, diabetes, chronic kidney disease, or recurrent stroke prevention), give most patients thiazide-type diuretics. Consider using an angiotensin-converting enzyme (ACE) inhibitor, beta-adrenergic blocker, calcium channel blocker (CCB), angiotensin-receptor blocker (ARB), or a combination.
❑ For stage 2 hypertension (SBP ≥ 160 mm Hg, or DBP ≥ 100 mm Hg) in the absence of compelling indications, give most patients a two-drug combination (usually a thiazide-type diuretic and an ACE inhibitor, ARB, CCB, or beta-adrenergic blocker).
❑ If the patient has one or more compelling indications, base drug treatment on benefits from outcome studies or existing clinical guidelines. Treatment may include the following, depending on indication:
– Heart failure — diuretic, beta-adrenergic blocker, ACE inhibitor, ARB, or aldosterone antagonist
– High coronary disease risk — diuretic, beta-adrenergic blocker, ACE inhibitor, or CCB
– Diabetes — diuretic, beta-adrenergic blocker, ACE inhibitor, or CCB
– Chronic kidney disease — ACE inhibitor or ARB
– Postmyocardial failure — ACE inhibitor, beta-adrenergic blocker, or aldosterone antagonist
– Recurrent stroke prevention — diuretic or ACE inhibitor.
Give other antihypertensive drugs as needed.
❑ If the patient fails to achieve the desired blood pressure, continue lifestyle modifications and optimize drug dosages or add additional drugs until the goal blood pressure is achieved. Also, consider consultation with a hypertension specialist.
Treatment of secondary hypertension focuses on correcting the underlying cause and controlling hypertensive effects.
Typically, hypertensive emergencies require parenteral administration of a vasodilator or an adrenergic inhibitor or oral administration of a selected drug, such as nifedipine, captopril, clonidine, or labetalol, to rapidly reduce blood pressure. The initial goal is to reduce mean arterial blood pressure by no more than 25% (within minutes to hours) then to 160/110 within 2 hours while avoiding excessive falls in blood pressure that can precipitate renal, cerebral, or myocardial ischemia.
Examples of hypertensive emergencies include hypertensive encephalopathy, intracranial hemorrhage, acute left-sided heart failure with pulmonary edema, and dissecting aortic aneurysm. Hypertensive emergencies are also associated with eclampsia or severe gestational hypertension, unstable angina, and acute myocardial infarction.
Hypertension without accompanying symptoms or target-organ disease seldom requires emergency drug therapy.

Pregnancy-induced hypertension:
Treatment
(Professional Guide to Diseases (Eighth Edition))
Therapy for preeclampsia is designed to halt the disorder’s progress — specifically, the early effects of eclampsia, such as seizures, residual hypertension, and renal shutdown — and to ensure fetal survival. Some physicians advocate the prompt induction of labor, especially if the patient is near term; others follow a more conservative approach. Therapy may include complete bed rest to increase placental perfusion, reduce hypertension, and evaluate response to therapy. Antihypertensive therapy doesn’t alter the potential for developing eclampsia. Diuretics aren’t appropriate during pregnancy.
If the patient’s blood pressure fails to respond to bed rest and sedation and persistently rises above 160/100 mm Hg, or if central nervous system irritability increases, magnesium sulfate may produce general sedation, promote diuresis, and prevent seizures. Cesarean birth or oxytocin induction may be required to terminate the pregnancy.
Emergency treatment of eclamptic seizures consists of immediate administration of magnesium sulfate (I.V. drip), oxygen administration, and electronic fetal monitoring. After the seizures subside and the patient’s condition stabilizes, delivery should proceed with induction of labor or cesarean birth, depending upon the circumstances.
Adequate nutrition, good prenatal care, and control of pre-existing hypertension during pregnancy decrease the incidence and severity of preeclampsia. Early recognition and prompt treatment of preeclampsia can prevent progression to eclampsia.

Pulmonary hypertension:
Treatment
(Professional Guide to Diseases (Eighth Edition))
Treatment usually includes oxygen therapy to decrease hypoxemia and resulting pulmonary vascular resistance. It may also include vasodilator therapy (nifedipine, diltiazem, or prostaglandin E). For patients with right-sided heart failure, treatment also includes fluid restriction, cardiac glycosides to increase cardiac output, and diuretics to decrease intravascular volume and extravascular fluid accumulation. Treatment also aims to correct the underlying cause.
Some patients with pulmonary hypertension may be candidates for heart-lung transplantation to improve their chances of survival.

Renovascular hypertension:
Treatment
(Professional Guide to Diseases (Eighth Edition))
Surgery, the treatment of choice, is performed to restore adequate circulation and to control severe hypertension or severely impaired renal function by renal artery bypass, endarterectomy, arterioplasty or, as a last resort, nephrectomy. Balloon catheter renal artery dilation is used in selected cases to correct renal artery stenosis without the risks and morbidity of surgery. Symptomatic measures include antihypertensives, diuretics, and a sodium-restricted diet.
Medications that may be used in an attempt to control blood pressure include diuretics, beta-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, and alpha-adrenergic blockers. Diazoxide or nitroprusside may be given in the hospital if symptoms are acute. Response to medications is highly individual and the dosage or specific drug used may need frequent adjustment.
Lifestyle changes may be recommended, including weight, exercise, dietary adjustments, smoking cessation, and avoidance of alcohol. These habits add to the effects of hypertension in causing complications.

Blood pressure increase [Hypertension]:
Patient counseling
(Professional Guide to Signs & Symptoms (Fifth Edition))
Encourage the patient to lose weight, if necessary, and to restrict sodium intake. Suggest that he participate in an exercise or stress management program as well. Then teach the patient how to monitor his blood pressure so that he can evaluate the effectiveness of drug therapy and lifestyle changes. Have him record blood pressure readings and symptoms, and ask him to share this information on his return visits.

Give other antihypertensive drugs as needed.
❑ If the patient fails to achieve the desired blood pressure, continue lifestyle modifications and optimize drug dosages or add additional drugs until the goal blood pressure is achieved. Also, consider consultation with a hypertension specialist.
UNDER STUDY: Studies have shown that omega-3 fatty acids used in the treatment of hypertension significantly reduce total cholesterol, low-density lipoprotein cholesterol, and triglyceride levels and lower systolic and diastolic blood pressure.
Clinical tip The treatment for renal artery stenosis includes the use of ACE inhibitors and renal artery stents.
Hypertensive emergencies
Examples of hypertensive emergencies include hypertensive encephalopathy, intracranial hemorrhage, acute left-sided heart failure with pulmonary edema, and dissecting aortic aneurysm. Hypertensive emergencies are also associated with eclampsia and severe pregnancy-induced hypertension, unstable angina, and acute MI.
Typically, hypertensive emergencies require parenteral administration of a vasodilator or an adrenergic inhibitor or oral administration of a selected drug, such as nifedipine, captopril, clonidine, or labetalol, to rapidly reduce blood pressure.

Stroke:
Treatment
(Handbook of Diseases)
Treatment options vary, depending on the type of stroke the patient experiences. Early medical diagnosis of the type of stroke coupled with new drug treatments can greatly reduce the long-term disability secondary to ischemia.
Surgery performed to improve cerebral circulation for patients with thrombotic or embolic stroke includes an endarterectomy (the removal of atherosclerotic plaque from the inner arterial wall) or a microvascular bypass (the surgical anastomosis of an extracranial vessel to an intracranial vessel).
Medications useful in treating stroke include:
❑ alteplase (recombinant tissue plasminogen activator), effective in emergency treatment of embolic stroke (See Restoring ischemic brain tissue with alteplase.) (Patients with embolic or thrombotic stroke who aren’t candidates for alteplase [3 to 6 hours poststroke] should receive aspirin or heparin.)
❑ long-term use of aspirin or ticlopidine, used as antiplatelet agents to prevent recurrent stroke
❑ anticoagulants (heparin, warfarin), which may be required to treat crescendo TIAs not responsive to antiplatelet drugs
❑ antihypertensives, antiarrhythmics, and antidiabetics, which may be used to treat risk factors associated with recurrent stroke.

Hypertension, pregnancy-induced:
Treatment
(Handbook of Diseases)
Adequate nutrition, good prenatal care, and control of preexisting hypertension with hydralazine during pregnancy decrease the incidence and severity of preeclampsia. Early recognition and prompt treatment of preeclampsia can prevent progression to eclampsia.
Therapy for preeclampsia is designed to halt the disorder’s progress — specifically, the early effects of eclampsia, such as seizures, residual hypertension, and renal shutdown — and to ensure fetal survival. Some physicians advocate the prompt induction of labor, especially if the patient is near term; others follow a more conservative approach.
Conservative measures
Therapy may include sedatives, such as phenobarbital, along with complete bed rest to relieve anxiety, reduce hypertension, and evaluate response to therapy. If renal function remains adequate, a high-protein, low-sodium, low-carbohydrate diet with increased fluid intake is recommended.
If blood pressure fails to respond to bed rest and sedation and persistently rises above 160/100 mm Hg or if CNS irritability increases, magnesium sulfate may produce general sedation, promote diuresis, reduce blood pressure, and prevent seizures.
Cesarean delivery
If these measures fail to improve the patient’s condition or if fetal life is endangered (as determined by stress or nonstress tests), cesarean delivery or oxytocin induction may be required to terminate the pregnancy.
Treatment for seizures
Emergency treatment of eclamptic seizures consists of immediate administration of I.V. diazepam, followed by magnesium sulfate (I.V. drip), oxygen administration, and electronic fetal monitoring. After the patient’s condition stabilizes, a cesarean delivery may be performed.

Pulmonary hypertension:
Treatment
(Handbook of Diseases)
Appropriate treatment usually includes oxygen therapy to decrease hypoxemia and resulting pulmonary vascular resistance. For patients with right-sided heart failure, treatment also includes fluid restriction, cardiac glycosides to increase cardiac output, and diuretics to decrease intravascular volume and extravascular fluid accumulation. An important goal of treatment is correction of the underlying cause.
CLINICAL TIP: Patients with primary pulmonary hypertension usually respond to epoprostenol (PGI2) as a continuous home infusion.
