Treatments for angina include medications to lower LDL cholesterol to very low levels to help reduce artery-narrowing plaque. Drugs that slow the heart rate and widen arteries can improve symptoms.

Many studies suggest that fiber-rich diets may help prevent heart disease. But most Americans eat only about 16 grams of fiber a day-far less than the recommended amounts.

Indirect evidence suggests that for people with atrial fibrillation who always take apixaban (Eliquis) every 12 hours as prescribed, it may be slightly better than once daily rivaroxaban (Xarelto).

A significant reduction in salt intake may directly lower blood pressure in even more people than previously believed.

When participants in a 2023 study ate a low-sodium diet for one week, the vast majority experienced an average 8-point drop in their systolic blood pressure compared to when they ate a high-salt diet for one week.

The weight-loss drug semaglutide is the first obesity treatment shown to help people live longer and have fewer cardiovascular problems. Developed as a drug for type 2 diabetes, semaglutide was first marketed as Ozempic; a higher-dose version for weight loss is called Wegovy. But because the drug is so popular, it can be hard to find, and it might not be covered by insurance.

The portfolio diet, which emphasizes foods rich in fiber and healthy fats, helps lower LDL cholesterol. A 2023 study suggests that the more closely people follow the diet, the lower their risk of cardiovascular disease. The diet discourages foods from animal sources and features foods from five main categories, including (1) plant protein such as legumes; (2) nuts and seeds; (3) foods rich in viscous fibers such as oatmeal, eggplant, and berries; (4) plant sterols such as phytosterol-enriched margarine; and (5) monounsaturated fats such as olive and canola oils.

Orthostatic hypotension, a condition that causes blood pressure to drop when a person stands up, can leave people dizzy and lightheaded. It can result from certain medications or health problems and becomes more common with age and frailty. Doctors sometimes worry that intensive blood pressure treatment contributes to the problem, but research suggests the opposite is true. Strategies to cope with symptoms of orthostatic hypotension include drinking plenty of fluids, wearing compression stockings, and taking care when rising from a chair or bed.

When people with atrial fibrillation sleep poorly, they may be more likely to have an episode of atrial fibrillation the next day, according to a 2023 study.

The carotid arteries, which run up the sides of the neck, can become clogged with plaque-a condition called carotid stenosis. But a carotid artery ultrasound to look for this problem is advisable in only a few specific circumstances, mostly in people with signs or symptoms of carotid stenosis. One sign is a distinctive whooshing sound called a bruit that a doctor can hear through a stethoscope placed over the artery. The tests are also routine in people who experience symptoms of a transient ischemic attack (TIA), or ministroke, which usually last only briefly.
