From the Guidelines
Antihypertensive medications can increase lifespan by approximately 1-5 years in patients with hypertension, with the greatest benefit seen in those with severe hypertension, where treatment can extend life by 3-5 years. The life-extending benefits of these medications, such as ACE inhibitors and calcium channel blockers, come from preventing organ damage to the heart, kidneys, and brain that occurs with chronic high blood pressure 1. According to the 2017 American College of Cardiology/American Heart Association hypertension guideline, the recommended blood pressure target is less than 130/80 mm Hg, with evidence showing continuing reduction in cardiovascular disease risk at progressively lower levels of achieved systolic blood pressure 1.
Key factors that influence the effectiveness of antihypertensive medications include:
- The severity of hypertension, with greater benefits seen in patients with severe hypertension
- Individual patient characteristics, such as the presence of comorbidities like diabetes or chronic kidney disease
- Adherence to medication and lifestyle modifications, including reduced sodium intake, regular exercise, weight management, limited alcohol consumption, and smoking cessation
Common medications used to treat hypertension include:
- Lisinopril (ACE inhibitor) at 10-40 mg daily
- Amlodipine (calcium channel blocker) at 5-10 mg daily These medications are typically taken long-term and work by reducing blood pressure, which decreases the risk of cardiovascular events such as heart attacks, strokes, and heart failure that can significantly shorten lifespan 1.
The evidence supporting the use of antihypertensive medications to reduce cardiovascular risk is strong, with a recent systematic review and network meta-analysis showing continuing reduction in cardiovascular disease risk at progressively lower levels of achieved systolic blood pressure 1. Overall, the use of antihypertensive medications, in conjunction with lifestyle modifications, can significantly increase lifespan and improve quality of life in patients with hypertension.
From the Research
Average Increase in Lifespan with Antihypertensive Medication
The average increase in lifespan associated with antihypertensive medication is not directly stated in the provided studies. However, the studies suggest that antihypertensive medication can reduce the risk of cardiovascular disease (CVD) events and mortality.
- A study published in JAMA in 2022 2 found that an SBP reduction of 10 mm Hg decreases the risk of CVD events by approximately 20% to 30%.
- Another study published in JAMA in 2002 3 found that antihypertensive therapy can reduce hypertension-related morbidity and mortality, but the optimal first-step therapy is unknown.
- A study published in the American Journal of Hypertension in 2021 4 found that lifestyle modification can lower blood pressure and reduce the need for antihypertensive medication.
Reduction in Cardiovascular Disease Risk
The studies suggest that antihypertensive medication can reduce the risk of CVD events, including:
Coronary heart disease
Heart failure
Stroke
Peripheral arterial disease
The study published in JAMA in 2002 3 found that thiazide-type diuretics are superior in preventing one or more major forms of CVD.
The study published in the Journal of the American College of Cardiology in 2018 5 found that angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) have similar efficacy in reducing CVD risk, but ARBs have fewer adverse events.
Lifestyle Modification and Antihypertensive Medication
The studies suggest that lifestyle modification can be an effective way to reduce blood pressure and reduce the need for antihypertensive medication.
- The study published in the American Journal of Hypertension in 2021 4 found that lifestyle modification can lower blood pressure and reduce the need for antihypertensive medication.
- The study published in Hypertension in 2021 6 found that physical activity is a critical component of first-line treatment for elevated blood pressure or cholesterol.
