What is the most appropriate initial antihypertensive medication for a patient with hypertension and left ventricular hypertrophy?

From the Guidelines

The most appropriate initial antihypertensive medication for a patient with hypertension and left ventricular hypertrophy (LVH) is an angiotensin-converting enzyme (ACE) inhibitor such as lisinopril (starting at 20 mg daily). This recommendation is based on the most recent and highest quality study available, which suggests that ACE inhibitors are preferred for patients with LVH because they effectively lower blood pressure and promote regression of LVH by blocking the renin-angiotensin-aldosterone system 1. The patient's condition, with a blood pressure of 150/110 mm Hg and left ventricular hypertrophy, requires immediate attention to reduce the risk of cardiovascular morbidity and mortality. Key considerations in managing this patient's hypertension include:

• Monitoring blood pressure regularly and titrating medication doses as needed to achieve a target blood pressure of less than 130/80 mmHg
• Implementing lifestyle modifications, such as sodium restriction, regular exercise, and weight management, alongside pharmacological therapy
• Considering alternative medications, such as angiotensin II receptor blockers (ARBs) or calcium channel blockers, if the patient cannot tolerate ACE inhibitors due to side effects The European Society of Cardiology/European Society of Hypertension guidelines recommend treating patients with hypertension and LVH with ACE inhibitors or ARBs as first-line therapy 1. Additionally, the American College of Cardiology/American Heart Association guidelines suggest that ACE inhibitors and ARBs are effective in reducing the risk of heart failure and cardiovascular events in patients with hypertension and LVH 1. Overall, the use of ACE inhibitors, such as lisinopril, is supported by the most recent and highest quality evidence as the most appropriate initial antihypertensive medication for patients with hypertension and LVH.

DOSAGE & ADMINISTRATION 2. 1 Hypertension Initial Therapy in adults: The recommended initial dose is 10 mg once a day. Dosage should be adjusted according to blood pressure response. The usual dosage range is 20 mg to 40 mg per day administered in a single daily dose. Doses up to 80 mg have been used but do not appear to give greater effect Use with diuretics in adults If blood pressure is not controlled with lisinopril tablets alone, a low dose of a diuretic may be added (e.g., hydrochlorothiazide, 12. 5 mg). After the addition of a diuretic, it may be possible to reduce the dose of lisinopril tablets. The recommended starting dose in adult patients with hypertension taking diuretics is 5 mg once per day.

The most appropriate initial antihypertensive medication for a patient with hypertension and left ventricular hypertrophy is lisinopril.

• The recommended initial dose of lisinopril is 10 mg once a day.
• The dosage should be adjusted according to blood pressure response.
• The usual dosage range is 20 mg to 40 mg per day administered in a single daily dose. 2 2 2

Initial Assessment and Treatment

The patient's blood pressure readings indicate hypertension, and the presence of left ventricular hypertrophy (LVH) suggests that the patient is at increased risk for cardiovascular complications.

Appropriate Initial Antihypertensive Medication

• The most appropriate initial antihypertensive medication for a patient with hypertension and left ventricular hypertrophy is an angiotensin-converting enzyme (ACE) inhibitor, such as lisinopril 3, 4, 5.
• ACE inhibitors have been shown to reduce cardiac output and preload to the left ventricle, reduce left ventricular hypertrophy, and lower renal vascular resistance, thereby increasing renal blood flow 3.
• The use of ACE inhibitors, such as lisinopril, is supported by studies that demonstrate their effectiveness in reducing blood pressure and promoting regression of left ventricular hypertrophy 3, 4, 5.
• Other antihypertensive agents, such as hydrochlorothiazide and metoprolol, may also be effective in reducing blood pressure, but they are not the first-line treatment for patients with left ventricular hypertrophy 3, 6, 7.

Treatment Approach

• The treatment approach should aim to lower total peripheral resistance, spare cardiac output, and maintain or improve blood flow to target organs 3.
• Controlling arterial pressure, sodium restriction, and weight loss can also facilitate the regression of left ventricular hypertrophy 4.
• The choice of antihypertensive agents should be individualized based on the patient's specific needs and risk factors 6, 4, 5.

Next Steps

• Based on the patient's presentation and medical history, the most appropriate next step would be to begin drug therapy with an ACE inhibitor, such as lisinopril (Zestril) 20 mg once daily 3, 4, 5.
