Hypertension Management

Diagnosis and Assessment

• Patients with severely elevated blood pressure (>180/120 mmHg) should be assessed for signs of end-organ damage, including hypertensive encephalopathy, intracerebral hemorrhage, acute myocardial infarction, acute left ventricular failure with pulmonary edema, unstable angina, aortic dissection, and eclampsia, as recommended by the American Heart Association 1
• Hypertensive emergencies are defined as a severe elevation of blood pressure (>180/120 mmHg) associated with evidence of acute end-organ damage, requiring hospitalization in an intensive care unit for continuous blood pressure monitoring and administration of parenteral antihypertensive medications, as recommended by the American Heart Association and American College of Cardiology 2, 3, 4
• Hypertensive urgency is defined as severe blood pressure elevation (typically >180/120 mmHg) without evidence of acute end-organ damage, requiring blood pressure reduction within 24-48 hours, and can usually be managed in an outpatient setting 5

Treatment Goals and Monitoring

• The primary goal is to reduce mean arterial pressure by no more than 25% in the first hour, with a secondary goal of reducing blood pressure to 160/100-110 mmHg within 2-6 hours in patients with hypertensive emergency, as recommended by the American College of Cardiology 1
• The American Heart Association advises against excessive reductions in blood pressure that may precipitate renal, cerebral, or coronary ischemia 1
• Patients should be monitored for at least several hours to ensure stability before discharge, with vital signs, especially blood pressure, checked every 30 minutes during the first 2 hours, and follow-up scheduled within 24 hours to prevent undetected progression to hypertensive emergency, with a strength of evidence based on expert opinion and clinical trials 1

Medication Management

• The American Heart Association recommends avoiding the use of immediate-release nifedipine for the initial treatment of hypertensive emergencies or urgencies 1
• The American College of Cardiology suggests initiating oral antihypertensive therapy as soon as possible in patients with hypertensive emergency 1
• Combination therapy with a RAS blocker (ACE inhibitor or ARB) plus either a dihydropyridine CCB or diuretic is considered for most patients, with fixed-dose single-pill combinations recommended for better adherence, as recommended by the European Society of Cardiology 5
• Patients with specific comorbidities, such as coronary artery disease, heart failure, or renal impairment, require tailored treatment approaches, including the use of beta-blockers, calcium channel blockers, ACE inhibitors, or ARBs, as recommended by the American Heart Association and American College of Cardiology 4
• The following intravenous medications are recommended for acute hypertensive emergencies:

Special Considerations

• For patients with aortic dissection, the American College of Cardiology recommends reducing systolic blood pressure to <120 mmHg within the first hour using esmolol + nitroprusside 3
• For patients with preeclampsia/eclampsia, the American College of Cardiology suggests reducing systolic blood pressure to <140 mmHg within the first hour, often using hydralazine 3
• Beta-blockers should be used with caution in patients with suspected catecholamine excess, such as pheochromocytoma or cocaine toxicity 4
• The European Society of Cardiology recommends aiming for a treated systolic BP of 120-129 mmHg to reduce cardiovascular risk 5
• Protracted follow-up until hypertension-mediated organ damage has regressed, monitoring specifically for renal function improvement, reduction in proteinuria, and regression of left ventricular mass, as suggested by the European Society of Cardiology 6
• Continue with monthly follow-up visits until target blood pressure is reached, to ensure long-term blood pressure control and monitor for complications, with a strength of evidence based on expert opinion and clinical trials 1
