People with treatment-resistant hypertension successfully reduced their blood pressure by adopting the Dietary Approaches to Stop Hypertension (DASH) eating plan, losing weight and improving their aerobic fitness by participating in a structured diet and exercise program at a certified cardiac rehabilitation facility, according to new research published in the American Heart Association’s flagship journal Circulation.
Uncontrolled high blood pressure (130/80 mm Hg or higher) despite the use of three or more medications of different classes including a diuretic to reduce blood pressure is a condition known as resistant hypertension. Although estimates vary, resistant hypertension likely affects about 5% of the general global population and may affect 20% to 30% of adults with high blood pressure. Resistant hypertension is also associated with end-organ damage and a 50% greater risk of adverse cardiovascular events, including stroke, heart attack and death.
Diet and exercise are well-established treatments for high blood pressure. In June 2021, the American Heart Association advised that physical activity is the optimal first treatment choice for adults with mild to moderately elevated blood pressure and blood cholesterol who otherwise have low heart disease risk.
