Hypertension in peripheral arterial disease

Area of Science:

• Cardiovascular Medicine
• Vascular Surgery
• Hypertension Research

Background:

• Peripheral arterial disease (PAD) of the lower limbs is linked to substantial cardiovascular morbidity and mortality.
• Intermittent claudication, a common PAD symptom, independently predicts a three-fold increase in cardiovascular death and a two-to-five fold increase in all-cause mortality.
• Hypertension is a significant risk factor for vascular disorders, including PAD, with a high comorbidity rate between the two conditions.

Purpose of the Study:

• To highlight the increased cardiovascular risk in patients with coexisting PAD and hypertension.
• To address the lack of consensus on specific antihypertensive treatment strategies for PAD patients.
• To emphasize the importance of reducing global cardiovascular risk over solely managing blood pressure or PAD symptoms.

Main Methods:

• Review of existing literature on PAD, intermittent claudication, and hypertension.
• Analysis of the epidemiological link and shared risk factors between PAD and hypertension.
• Discussion of current treatment considerations and the need for outcome studies.

Main Results:

• Patients with both PAD and hypertension face a greatly elevated risk of myocardial infarction and stroke.
• A significant percentage of PAD patients present with hypertension (35-55%), and a smaller percentage of hypertensive patients have intermittent claudication (2-5%).
• Limited controlled studies exist for antihypertensive therapy in this specific population.

Conclusions:

• The management of hypertension in PAD patients requires a focus on reducing overall cardiovascular risk.
• Antiplatelet drugs, ACE-inhibitors, and statins are recommended as part of a comprehensive risk reduction strategy.
• Further outcome studies are essential to guide specific antihypertensive treatments in patients with PAD.
