How do I make sense of my medication orders?

Hospital discharge instructions about medications can be complicated and confusing. Having a family member or friend along as a second set of ears during the discharge meeting can be helpful.

Alcohol and heart health: A complex relationship

The association between alcohol and cardiovascular disease is both complex and controversial. There's no evidence of an increased risk for the most common forms of heart disease in people who stay within the limits for moderate drinking. Whether light to moderate drinking can lower a person's risk is impossible to answer with currently available evidence. But there is clear, consistent evidence that heavier drinking-an average of three or more drinks per day-is linked to worse outcomes for every type of heart disease.

Infections, vaccines, and heart disease: What you need to know

Getting vaccinated against influenza (flu), COVID-19, and pneumonia is especially important for people who have cardiovascular disease. The coughing and congestion that commonly occur with respiratory infections can make breathing more difficult, and the potential drop in oxygen puts added stress on the heart. Serious infections sometimes trigger sepsis, which happens when the immune system is overwhelmed or goes into overdrive, causing symptoms such as a rapid heart rate, very fast breathing, and low blood pressure. These complications can lead to a heart attack.

Staying healthy after a heart procedure

After common heart procedures or surgeries, medications to help prevent heart attacks and strokes are essential. These include a combination of drugs to prevent blood clots (which is known as dual antiplatelet therapy and usually taken for just one year); drugs to lower LDL cholesterol down to 70 milligrams per deciliter or lower; and drugs to keep blood pressure and blood sugar in a healthy range.

Heart disease and depression: A two way street

A heart disease diagnosis may trigger a bout of depression. But having depression can also leave people more vulnerable to heart disease. Some of the overlap stems from shared lifestyle factors, such as inactivity and an unhealthy diet. In addition to addressing those issues, other safe and effective ways to ease depression include working with a therapist, using a light box, and taking medications.

Eating diverse flavonoid foods may provide extra health protection

Eating a variety of flavonoid-rich foods may offer greater protection against cardiovascular disease and cancer than eating only a few high-flavonoid foods, according to a 2025 study.

When should you worry about abnormal heartbeats?

People commonly experience heart palpitations, which feel like the heart flutters or skips a beat, or beats at a faster rate or in an irregular rhythm. They often last only seconds and can be unsettling. For the most part, palpitations are nothing to worry about. Still, these unusual heart sensations may indicate something more serious, such as atrial fibrillation, supraventricular tachycardia, or ventricular tachycardia. Palpitations that persist or cause other symptoms (such as lightheadedness) should be evaluated by a doctor.

Modified DASH diet lowers blood pressure in people with diabetes

For people with diabetes, a modified version of the Dietary Approaches to Stop Hypertension (DASH) diet can lower their blood pressure. Called DASH4D, it has fewer carbohydrates, more unsaturated fat, and slightly reduced amounts of potassium.

People with Lp(a) gene variant may benefit from daily aspirin

An inexpensive blood test that checks for a genetic variant of Lp(a)-a fatty particle similar to LDL cholesterol-may help clarify who might benefit from a daily low-dose aspirin, according to a 2025 review of study findings.

High levels of ocean microplastics linked to heart-related risks

According to a 2025 study, people living near coastlines with high levels of marine microplastics had higher rates of heart disease than those living close to coastlines with less plastic pollution.
