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.

Compared with analog scales, digital scales are more accurate and easier to read. Many smart scales include added features such as smartphone connectivity and body composition estimates.

Tiny mesh tubes called stents, used to prop open heart arteries, can relieve stable angina (chest pain with exertion or emotional stress) in many people with coronary artery disease. But this treatment-which carries a risk of complications and a high cost-should be reserved only for people who don't get relief from drug therapy. Stents do not prevent future heart attacks or improve survival compared with drug therapy. Angina usually results from arteries that are more than 70% blocked, but most heart attacks occur in arteries that are narrowed by only about 40% or less but harbor plaque that ruptures without warning. The resulting blood clot blocks blood flow, triggering a heart attack.

About a third of healthy people-and about 60% of people with high blood pressure-are salt sensitive, meaning they have an exaggerated response to dietary sodium. But an estimated one in 10 people may have inverse salt sensitivity: their blood pressure goes up when they eat less salt. Understanding the genetic basis of these differences may one day improve the treatment of blood pressure.

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.

A 2023 study found that a mindfulness training program that improves self-awareness may help people with high blood pressure follow a heart-healthy diet.

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.

Metabolic syndrome is a constellation of interrelated health conditions that significantly increases the risk for heart attacks, strokes, diabetes, and more. A diagnosis requires at least three of the following risk factors: obesity, high blood sugar, high triglycerides, low HDL (good) cholesterol, or high blood pressure. Metabolic syndrome can be reversed if it's recognized. Losing weight is central to reducing many of its features. Lowering elevated blood pressure, blood sugar, and cholesterol levels also plays a major role in reducing the risk for heart disease and stroke.

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.

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