ABSTRACT: Hypertension is a common comorbidity in patients with diabetes, and adequate control of blood pressure significantly reduces the risk of macrovascular and microvascular complications. Patients with diabetes should achieve a target blood pressure of less than 130/80 mm Hg. The use of angiotensin-converting enzyme inhibitors may slow progression to kidney failure and cardiovascular mortality; these agents are the preferred therapy for managing coexisting diabetes and hypertension. Angiotensin receptor blockers can prevent progression of diabetic kidney disease and are a first-line alternative for patients intolerant of angiotensin-converting enzyme inhibitors. Thiazide diuretics provide additional antihypertensive effects when combined with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. With lower doses of these drugs, the risk of clinically significant metabolic alterations is minimal. Beta blockers and calcium channel blockers also have beneficial effects in managing hypertension in patients with diabetes. Beta blockers reduce cardiovascular events and are useful in a multidrug regimen. Dihydropyridine calcium channel blockers should be reserved for patients intolerant of preferred agents or those who need additional therapy to achieve target blood pressure. Many patients with diabetes require combination therapy with multiple antihypertensive agents.
Screening for High Blood Pressure - Putting Prevention into Practice
ABSTRACT: The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommends lifestyle modification for all patients with hypertension or prehypertension. Modifications include reducing dietary sodium to less than 2.4 g per day; increasing exercise to at least 30 minutes per day, four days per week; limiting alcohol consumption to two drinks or less per day for men and one drink or less per day for women; following the Dietary Approaches to Stop Hypertension eating plan (high in fruits, vegetables, potassium, calcium, and magnesium; low in fat and salt); and achieving a weight loss goal of 10 lb (4.5 kg) or more. Alternative treatments such as vitamin C, coenzyme Q10, magnesium, and omega-3 fatty acids have been suggested for managing hypertension, but evidence for their effectiveness is lacking.
ABSTRACT: High blood pressure is often difficult to control. Resistant hypertension is blood pressure above goal despite adherence to a combination of at least three antihypertensive medications of different classes, optimally dosed and usually including a diuretic. The approach to blood pressure that is apparently difficult to control begins with an assessment of the patient's adherence to the management plan, including lifestyle modifications and medications. White-coat hypertension may need to be ruled out. Suboptimal therapy is the most common reason for failure to reach the blood pressure goal. Once-daily fixed-dose combination pills may improve control through the synergism of antihypertensive agents from different classes and improved adherence. Truly drug-resistant hypertension is commonly caused by chronic kidney disease, obstructive sleep apnea, or hyperaldosteronism, all of which can lead to fluid retention. Higher doses of diuretics (or a change to a loop diuretic) are usually needed. Other strategies include adding an alpha blocker, alpha-beta blocker, clonidine, or an aldosterone antagonist (e.g., spironolactone). Particularly in patients with diabetes or renal disease, combining a long-acting nondihydropyridine with a dihydropyridine calcium channel . blocker can also be considered. Obesity, heavy alcohol intake, high levels of dietary sodium, and interfering substances (especially nonsteroidal anti-inflammatory drugs) contribute to hypertension that is resistant or difficult to control.
Are Beta Blockers Effective First-line Treatments for Hypertension? - Cochrane for Clinicians
ABSTRACT: Risk factors for stroke should be evaluated in patients who have had a transient ischemic attack. Blood pressure, lipid levels, and diabetes mellitus should be controlled. When applicable, smoking cessation and weight loss also are important. Angiotensin-converting enzyme inhibitor therapy may help prevent stroke. Aspirin is the treatment of choice for stroke prevention in patients who do not require anticoagulation. Clopidogrel is an alternative therapy in patients who do not tolerate aspirin. Atrial fibrillation, a known cardioembolic source (confirmed thrombus), or a highly suspected cardioembolic source (e.g., recent large myocardial infarction, dilated cardiomyopathy, mechanical valve, rheumatic mitral valve stenosis) are indications for anticoagulation.
