Renal denervation is a minimally invasive procedure that destroys some of the nerves inside the renal arteries, which supply the kidneys. The procedure lowers blood pressure by disrupting communication between the brain and the kidneys that leads to elevated blood pressure. People with stubbornly high blood pressure may be candidates for the procedure, which is currently approved for use in Europe but not in the United States.

Heartburn can cause chest pain that may be mistaken for a heart attack, and vice versa. Heartburn causes more a burning sensation and is more likely to occur after a large meal. Heart attacks are often described as a feeling of tightness or pressure and are more likely to occur after physical activity or stress. People who aren’t sure about their symptoms should get to an emergency room for an evaluation as soon as possible.

People who use artificial sweeteners such as aspartame (NutraSweet, Equal), acesulfame potassium (Sunnett, Sweet One), and sucralose (Splenda) may have a higher risk of cardiovascular disease compared with people who avoid these products. These zero-calorie sweeteners might not help people lose weight, and experts postulate that artificial sweeteners may trigger inflammation and alter normal metabolism, the gut microbiome, and blood vessels in ways that promote type 2 diabetes, unhealthy cholesterol levels, and high blood pressure.

Costochondritis, which is caused by inflammation of the cartilage between the ribs and the breastbone, causes chest pain that’s often mistaken for a heart problem.

Aerobic and muscle-building exercises can trigger physiological changes that improve blood vessels and metabolism in ways that help prevent all the major risk factors that contribute to heart disease. These include high blood pressure, diabetes, obesity, and unhealthy cholesterol levels. Exercise can also improve mental health problems such as depression and stress, which are common but underrecognized risks for heart disease.
