Heart failure refers to the condition of the heart becoming incapable of pumping sufficient blood to fulfill the requirement of the body.
The symptoms and signs of heart failure include excessive amount of tiredness, shortness of breath, and swelling in legs. The shortness of breath aggravates during exercise or exertion, while lying down and while sleeping at night. Even after treatment, a person with heart problem should limit his exertion or exercise.
The causes of heart failure are varied, and include commonly the coronary artery disease including a previous heart attack, atrial fibrillation, high blood pressure, cardiomyopathy, and valvular heart disease. These conditions change the structure or the functioning of the heart. The two types of heart failure include systolic heart failure and diastolic heart failure. The left side failure is characterized by excessive breathing. Other sign of left ventricular failure include a laterally displaced apex beat taking place on enlargement of the heart. In case of right side failure, physical condition exhibits pitting peripheral edema, liver enlargement, and ascitis. On the right ventricular pressure increasing, a compensatory increase in the strength of contraction takes place.
As per studies conducted, the percentage of risk factors vary from country to country, however, the underlying causes are the same. Some of the risk factors include Ischemic heart disease, cigarette smoking, obesity, hypertension, diabetes, and valvular heart disease.
Heart failure due to systolic dysfunction has been more common and easily recognizable. It can simply be defined as the failure of the pumping function of the heart. The strength of the ventricular contraction leads to the creation of inadequate volume of stroke. Heart failure due to diastolic dysfunction is characterized by the failure of ventricle to relax adequately due to stiffer ventricular wall.
The treatment has been numerous and varied with the latest in the list the stem cell therapy which has not yet been established as en effective treatment method in heart diseases
