What Every Woman Should Know About Heart Failure

One thing that we have discovered is that many aspects of heart failure differ between men and women. For both sexes, heart failure comes about as a result of coronary artery disease, or chronic hypertension (high blood pressure). Usually, the symptoms of heart failure, and the treatment of it, are similar in men and women, but there are some differences.
 
There are a few aspects of heart failure that pertain especially to women. These include the causes of heart failure in women, the age of women who develop heart failure, the symptoms caused by the heart failure, and how doctors treat heart failure in women. If you’re a woman who has heart failure, you should make sure you know these differences.

Causes of Heart Failure That Are Especially Important in Women
Hypertension The most common medical problems that lead to heart failure are hypertension and coronary artery disease (CAD). Of these, hypertension is the leading cause in both sexes. However, hypertension is substantially more likely to cause heart failure in women than in men. Hypertension increases the risk of developing heart failure by 300% in women, but “only” 200% in men. Among women with heart failure, hypertension is the underlying cause in 59% of cases in women, compared to 39% in men. So while it’s important for anyone with hypertension to be treated adequately, it’s even more so for women.

Diastolic Heart Failure In diastolic heart failure, cardiac function deteriorates because the heart muscle becomes stiff, and the heart has difficulty filling with blood. As a result, the amount of blood that is pumped around the body with each beat is significantly reduced (making you tired and exercise intolerant), and the blood that is unable to fill the heart “backs up” into the lungs (producing pulmonary congestion). While this condition can occur in anyone, it’s more prominent in women than men.

Diabetes Diabetes by itself doesn’t cause heart failure, but people with diabetes have a high incidence of conditions that do, such as CAD and hypertension. Furthermore, for reasons that are not understood, women with diabetes are twice as likely to develop heart failure than men with diabetes.

Obesity 
Women who are obese have a high risk of developing heart failure that is 50% higher than women who are normal weight. Obese men also have a higher risk of heart failure, but the excess risk from obesity is not thought to be as high in men as it is in women.

Chemotherapy Certain drugs used for chemotherapy can cause cardiac toxicity that can lead to heart failure. Women tend to be exposed to these chemotherapy agents a lot more often than men, in particular, for the treatment of breast cancer.

Stress Cardiomyopathy Stress cardiomyopathy, also known as “broken heart syndrome,” is a form of sudden, severe heart failure that is triggered by extreme emotional trauma. While this condition can be found in either sex, it’s far more common in women, and may be related to microvascular angina – a condition that is more common in women.
 
Age of Women with Heart Failure Women who develop heart failure usually do so at an older age than men who develop heart failure. Unfortunately, as past clinical trials tended to exclude people over the age of 65, this means that relatively little data has been collected from clinical trials showing how older women with heart disease respond to treatment. Recently, researchers have been including a sufficient number of elderly women in their clinical trials, and this shortcoming is slowly being rectified.

Symptoms of Heart Failure in Women
As mentioned previously, the symptoms of heart failure in men and women are largely the same – gradually worsening fatigue, dyspnea, exercise intolerance, and edema. However, some scientific studies suggest that women with heart failure are more likely to experience significant dyspnea and edema than men.
Response to Treatment in Women 
As stated, clinical trials evaluating the treatment of heart failure have tested considerably more men than women. Nevertheless, the data that is available strongly suggests that women with heart failure respond to treatment just as favorably as men.

Differences in How the Hearts of Men and Women Respond to Cardiac Stress
In studies with animals and in clinical trials, evidence is accumulating to suggest that the heart muscles of men and women react differently to various kinds of physiologic stress. Several animal studies have looked at how the hearts of males and females react to experimental conditions that have been designed to produce heart failure. These studies have consistently shown that female cardiac muscle tends to respond by making various adaptions that help to prevent heart failure, whereas male cardiac muscle fails more quickly.

Clinical trials on people have shown the same thing. In those with aortic stenosis (a narrowing of the aortic valve, which greatly increases the pressure and stress in the left ventricle), premenopausal women develop cardiac hypertrophy (thickening of the heart muscle) more readily than men. This hypertrophy reduces wall stress, delays the onset of dilated cardiomyopathy and thus, reduces the risk of heart failure. Interestingly, postmenopausal women do not show this same adaption, and they develop heart failure at the same rate as men, suggesting that female hormones may play a part. However, clinical trials evaluating this have given contradictory results.

These findings may help to explain why women develop heart failure later than men, and why women who have heart failure tend more often to have diastolic heart failure than men.
Still, having said this, all we can say with confidence at the moment is that the hearts of men and women respond somewhat differently to various kinds of physiological stress.
Outcome of Heart Failure in Women 
Evidence suggests that, even though they usually develop heart failure at a later age than men, women with heart failure tend to survive longer than men.

This relatively good news for women who have heart failure is counter-balanced by some clinical evidence that suggests that doctors tend to be less aggressive when treating women with heart failure when compared with men. One reason for this may be that women may tend to minimize their cardiac symptoms when talking to their doctors. Those doctors who do not push their patients for a full accounting of symptoms may not be aware of just how sick their female patients actually are.

Therefore, it’s very important for anyone, male or female, who has symptoms of heart failure – especially worsening fatigue or dyspnea – to make sure their doctors are aware of it. But, maybe women need a little extra reminding of how important it is.

Why heart failure is not as life-threatening as a heart attack

Heart failure may be a serious health hazard but not life-threatening like a heart attack, health experts say.

"Heart failure refers to the heart's inability to circulate blood through the body. Blood flow is slower than normal, which compromises the blood flow to the vital organs of the body like kidneys, liver and brain, leading to the malfunction of these organs," Subhash Chandra, Chairman, Cardiology, BLK Super Speciality Hospital, New Delhi, told IANS.

Heart failure is not similar to a heart attack and it is important for people to understand the difference, the experts said.

"Heart failure refers to the condition wherein the blood pumping capacity of the heart is reduced. Heart attack is secondary to blocked coronary circulation. Blood supply to muscles of heart is cut or drastically reduced," Salil Shirodkar, Interventional Cardiologist at Mumbai's Nanavati Super Speciality Hospital, told IANS.

According to the experts, two types of heart dysfunctions can lead to heart failure -- systolic heart failure and diastolic failure.

Systolic heart failure is the most common cause of heart failure and occurs when the heart is weak and enlarged and the muscle of the left ventricle loses some of its ability to contract or shorten, whereas diastolic failure is when the muscle becomes stiff and loses some of its ability to relax.

As a result, the affected chamber has trouble filling with blood during the rest period that occurs after each heartbeat.

Heart failure is caused by many conditions that damage the heart muscle, including coronary artery disease (CAD), heart attack, cardiomyopathy -- disease of a heart muscle.

"The main causes of heart failure are blockages in the blood vessels supplying blood to the heart leading to heart attacks, weakness of the heart muscles either because of unknown reasons or because of some infection, drugs, diabetes, etc.; high blood pressure  is also one of the main causes of heart failure," Vishal Rastogi, Head of Department, Heart Failure Clinic, Fortis Escorts Heart Institute, told IANS.




Heart failure can also occur with heart defects present at birth or congenital heart defects.

"Children with congenital heart defects often have slower growth and development and they may be smaller than other children of the same age. They may also have life-long problems with learning difficulties," Shantala Vadeyar, Group Medical Director, Department of Fetal and Maternal Medicine, Cloudnine Group of Hospitals, Mumbai, told IANS.

Early symptoms of heart failure are fatigue and shortness of breath. These affect daily activities such as walking, climbing stairs or carrying groceries.

The warning signs associated with heart failure includes acute shortness of breath, coughing or wheezing, accumulation of excess fluid in body tissues, tiredness, fatigue, nausea, lack of appetite and an   elevated heart rate.

"Basically your heart tries to compensate for its lack of strength by beating more often to help deliver a sufficient amount of blood to your tissues and organs," Chandra explained.

However, heart failure can be prevented by having proper diet, daily exercise, swimming, jogging, adequate sleep, and minimising stress and tension.

Diabetic or hypertensive patients should be more careful; they should always take the medications as prescried by the doctor.

"As of now there's no known cure for heart failure, but there are steps that can be taken to prevent a weak heart from getting weaker," Chandra said.

"Controlling hypertension, regular medical follow-up with doctors, non-smoking and alcohol consumption in moderation and lifestyle modifications with an effective mix and match of diet, along with daily exercise, are the key to preventing heart failure," Shirodkar added.

For children with congenital heart defects, it is not all bad news, as some of these defects may be treatable.

"Many congenital heart defects (CHD) can also be treated and children can lead a normal life. It is important that CHD should be detected in the developing baby so that doctors can counsel parents to help them prepare for possible outcomes and surgical interventions," Vadeyar said.

Surgery may also sometimes prevent further damage to the heart and improve its functioning.
