Sleep apnea and heart disease: A weighty matter

Anti-obesity drugs, which can lead to dramatic weight loss, may improve symptoms of sleep apnea. This serious breathing disorder raises the odds of high blood pressure, heart attack, and stroke. Excess weight is the strongest risk factor linked with sleep apnea, which affects about 25% of men and 10% of women in the United States. Extra fat tissue in the neck and throat can narrow the airway, and extra weight on the chest and belly puts pressure on the lungs, which makes the normal process of inhaling and exhaling less effective.

Why all the buzz about inflammation — and just how bad is it?

Inflammation is the body’s response to an injury, allergy, or infection, a reaction that attempts to restore the health of the affected area. But that’s only part of the story, because there are two types of inflammation, and it’s important to know the difference—and what is and isn’t true about all types.

Tracking your afib with a smart watch? Avoid this pitfall

People with atrial fibrillation (afib) who own a smart watch capable of detecting the heart rhythm disorder may use it to track the frequency and duration of their bouts of afib. The information might help inform their physician's advice. However, afib notifications may cause people to become anxious and preoccupied with tracking their condition. For them, disabling the notifications may be a good idea.

Device of the month: Smart ring

Smart rings can do many of the same things a smart watch can, including heart rate monitoring, blood oxygen level measurement, and activity and sleep tracking.

Depression around time of pregnancy may raise risk of cardiovascular disease

A 2024 study suggested that women with perinatal depression, which can occur during or just after pregnancy, have significantly higher risks of developing later cardiovascular disease.

Drops in air pollution linked to fewer heart disease hospitalizations

A 2024 study found that when air pollution levels decreased during a five-year period in Italy, so did hospitalizations for heart-related emergencies. The results suggest that reducing air pollution could lower the prevalence of heart disease.

What's the right blood pressure?

U.S. guidelines define normal blood pressure as less than 120/80 millimeters of mercury (mm Hg). Studies have shown that the lower a person's blood pressure, the greater the heart health benefits. However, the "best" blood pressure number for someone depends on several factors, such as the person's health condition, lifestyle, family history, and personal goals. Depending on an individual's situation, a higher-than-normal number may be adequate.

Three times as many people have atrial fibrillation than previously known

According to a 2024 study, the rapid, irregular heart rhythm known as atrial fibrillation is three times more prevalent than previously thought, and now affects an estimated 10.5 million Americans.

Heart and soul: Spirituality in cardiovascular care

Most hospitals have chaplains who can provide emotional and spiritual support to patients and their families during challenging medical situations, such as impending heart surgery, a worsening bout of heart failure, or cardiac arrest. Spiritual care, which has been linked to improved health outcomes, encompasses but does not necessarily include formal religious practices. It aims to help people explore sources of comfort and hope while coping with the challenge of a diagnosis.

The wrong arm position might affect your blood pressure measurement

A 2024 study found that the accuracy of a blood pressure reading is compromised if a person's arm isn't in a certain position. For the most effective measurement, the person should be seated, feet flat on the floor, with the arm supported so the elbow is at heart level.
