Your brain on high blood pressure

High blood pressure not only can raise risk for a heart attack, but also can affect the brain. Keeping blood pressure normal can make brain injury from stroke less likely to happen and perhaps slow the natural decline in cognitive function. Just like with the heart, the best way to protect the brain from high blood pressure is to lower blood pressure if it's high and keep it as close to a normal level as possible.

Dealing with dizziness

Many people experience dizziness, or a feeling of being woozy or lightheaded, from time to time. In most instances it's triggered by a minor underlying problem, such as dehydration, a medication, or blood pressure fluctuations. Only rarely is dizziness caused by something more serious, such as a heart rhythm disturbance or stroke. However, even if dizziness isn't caused by something serious, it can lead to a dangerous fall, so it's important to prevent these episodes when possible. People should get emergency help for dizziness that is long-lasting, severe, or accompanied by other symptoms, such as difficulty walking or numbness.

Getting through grief

The American Psychiatric Association has recently added prolonged grief disorder to its official list of classified mental disorders. Someone may develop this disorder when someone close has died within the past 12 months. The person may experience intense longing for the deceased or preoccupation with thoughts about him or her. These feelings occur most of the day and nearly every day for at least a month. Recognizing the signs and seeking out help with talk therapy are the best approaches to help prevent it from evolving to depression.

How physical activity keeps your heart in good shape

Moderate-to-vigorous exercise appears to be the best way to boost cardiorespiratory fitness (CRF), which quantifies how well the heart and lungs supply oxygen to the muscles during physical activity. Higher CRF during midlife is linked to a lower risk of conditions closely tied to heart disease (including early signs of atherosclerosis, high blood pressure, and diabetes) later in life.

Nitrates in food and medicine: What's the story?

Nitrates are added to processed meats (such as bacon, ham, and deli meats) and are found naturally in leafy green vegetables (such as spinach and kale). But it's not clear how crucial these molecules are compared with other components of those foods, as dietary nitrate levels don't appear to affect heart disease risk. However, nitrate-based drugs are used to treat angina, a common symptom of coronary artery disease.

Do older adults benefit from blood pressure treatment?

A study published online Aug. 26, 2021, by The Lancet found that blood pressure treatment protects against heart attacks, strokes, and other major cardiovascular disease problems in people up to age 85 and possibly older. For people younger than 75, the study confirmed that people taking blood pressure medicines had 10% to 20% fewer cardiovascular disease problems. For people 75 to 84, there still was a 10% reduction. For people older than 85, the results were mixed, but there still appeared to be a benefit from blood pressure treatment.

A look at health screenings

Men are less likely than women to get regular exams and tests, especially when they are younger. But as they age, routine screenings are essential. There are certain tests most men should have at some point, including ones for colon cancer, high blood pressure, hepatitis C, diabetes, and HIV. Other tests men should consider if they are at high risk for specific ailments, such as abdominal aortic aneurysm, hepatitis B, and lung cancer.

Coffee and your blood pressure

A recent study alleviates concerns about coffee's role in heart disease and stroke and makes observations about coffee's physiological effects.

Treating low vitamin D levels may help people live longer

Treating people who have low levels of vitamin D with supplements may reduce their risk for heart attacks and death from any cause.

Seasonal changes and blood pressure

Some people with borderline high blood pressure have higher readings during winter, even high enough to need medicine to control it. In spring or summer, they might be able to reduce the dose or stop taking the medication. Losing excess weight and cutting back on salt also can help.
