women and heart disease

What Everyone Should Know About Women and Heart Disease

When we think of a victim of heart disease, we tend to think of men, but unfortunately, heart disease is the leading killer of both men and women in the United States. Heart disease includes the narrowing of the arteries that bring oxygen to the heart, heart failure, diseases of the heart muscles, inborn defects, and other conditions. Five hundred thousand American women die each year from heart diseases, and the risks increase as a woman ages.

The Change of Life

The Cleveland Clinic Heart Center explains that menopause changes the risks for women and heart disease. Post-menopause, a woman’s body experiences reduced estrogen production, changes in cholesterol levels, changes in the structure of blood vessels, and increased production of the clotting agent fibrinogen.

No one yet knows exactly how much a woman’s risk is affected by each of these changes, but they are definitely associated with greater heart disease risk. Women who have gone through menopause are two to three times more likely to suffer heart disease than a pre-menopausal woman of the same age. Women that have had a hysterectomy experience these same raised risk factors.

In the past, scientists studying women and heart disease hypothesized that hormone replacement therapy could help post-menopausal women fight heart disease; however, long-term studies do not confirm that preliminary idea and doctors no longer recommend hormone replacement therapy to battle heart disease. Menopause we cannot change, but other risk factors are under our control.

Using hormonal birth control (the pill or the patch) is considered safe for women under thirty-five. As of now, doctors do not have proof that birth control hormones can increase or decrease problems for women and heart disease, especially after the age of thirty-five. When talking about your heart disease risk factors with your doctor, get his or her opinion on your personal situation.

A Change of Lifestyle

Scientists studying women and heart disease find that women are knowledgeable about what lifestyles are associated with heart disease, but are also prone to having those lifestyles. For example, according to the National Institutes of Health, fifty-six million American women have high cholesterol, 33% of women have high blood pressure, and 62% of women are overweight. Despite these risks, women are less physically active than men, on average.

For women, as for men, there are a few good guidelines to a healthier heart. Habits such as not smoking, maintaining a healthy weight by regular activity or exercise, cutting down on the fatty foods, and getting your cholesterol tested can dramatically help prevent heart disease. Don’t become another statistic about women and heart disease.

rheumatic heart disease

Rheumatic Heart Disease is Treatable

Rheumatic heart disease, also called rheumatic fever, occurs when an untreated strep throat infection migrates to the joints and heart, causing fever, muscle aches, and possible permanent heart valve damage. Just as “rheumatism” refers to joint pain, “rheumatic” fever gets its name because one of its main symptoms is actually pain in the joints rather than the heart.

The National Institute of Health estimate that rheumatic heart disease develops in about 3% of untreated strep throat infections in the United States. Because mainly young people get strep, accordingly rheumatic heart disease mostly strikes people aged between six and fifteen years old.

Most people in the west who get strep will never develop rheumatic heart disease, because the strep throat infection is treated effectively with antibiotics. However, if fever, irregular heart beat, nodes under the skin, and other symptoms appear after a strep infection, a doctor will perform lab tests to diagnose rheumatic fever.

Penicillin treats rheumatic heart disease symptoms, including the contraction of the heart, which may damage heart valves; however, there is no cure for the disease, and patients must continue with penicillin injections. Some doctors argue this treatment should continue for the rest of the patient’s life. Left untreated, besides the symptoms of physical pain, rheumatic heart disease can cause permanent heart valve damage. Without surgery, heart valve damage can lead to fatal heart failure.

Cases And Treatment Worldwide

Doctors working with the Australian National Heart Foundation are working on a vaccine to prevent rheumatic fever. After an unexplained jump in the number of cases among the Aboriginal population of Australia from 2004 to 2006, doctors launched the world’s most advanced investigation of rheumatic heart disease.

In New Zealand as well, rheumatic fever is a problem among some populations, and the treatment there is penicillin shots every month for ten years. One famous rugby player, a childhood victim of rheumatic heart disease, admits to “getting lazy” about having his shots, and the symptoms of the disease returned to him as an adult. Luckily, he knew his problem and how to get help. Some people, especially those with little access to health care, simply suffer through fever attacks, and fall victim to heart valve failure.

In fact, the World Heart Federation in Geneva, Switzerland calls rheumatic fever a disease born of poverty. Though it is easily prevented by a good strep throat treatment, many young people of the world do not have access to the healthcare that would keep their heart valves healthy and extend their lives.
