Acute left ventricular failure occurs when an acute event results in the left ventricle being unable to move blood efficiently through the left side of the heart and into the systemic circulation. Cardiac output is the volume of blood ejected by the heart per minute. Stroke volume is the volume of blood ejected during each beat. Cardiac output is the product of stroke volume x heart rate. When blood cannot flow efficiently through the left side of the heart, there is a backlog of blood waiting in the left atrium , pulmonary veins and lungs.

The heart's pumping action moves oxygen-rich blood from the lungs to the left atrium, then on to the left ventricle, which pumps the blood to the rest of the body. The left ventricle supplies most of the heart's pumping power, so it's larger than the other chambers and essential for normal function. In left-sided or left ventricular heart failure, the left side must work harder to pump the same amount of blood. The percentage of blood the heart can pump with each beat is measured by a unit called ejection fraction , or EF. Watch an animation of heart failure. Right-sided heart failure The heart's pumping action moves "used" blood that no longer has oxygen in it back to the right atrium and on to the right ventricle. The right ventricle then pumps the blood back out of the heart and into the lungs to be replenished with oxygen. Right-sided or right ventricular heart failure usually occurs as a result of left-sided failure. Congestive heart failure, sometimes called CHF, requires quick medical attention. However, sometimes doctors use the terms congestive heart failure and heart failure interchangeably. As blood flow out of the heart slows, blood returning to the heart through the veins backs up.

They also have more hypertension and atrial fibrillation [3][9] but have less ischemic heart disease [11][12]. Background Heart failure HF is a major epidemic and a significant public health problem [1]. The clinical picture of these patients is different from patients with reduced LVF, lvf medical abbreviation.

Data regarding this is limited. Sociodemographic status including place of residence, ethnic background, education, background concurrent diseases as documented by the medical records, the causes of admission and drug prescription on discharge were recorded systematically from the medical records during hospitalization. Pulmonary oedema is where the lung tissue and alveoli are filled with interstitial fluid. Positive inotropes act to increase the contractility of the heart. The long term clinical outcome of patients with heart failure and preserved LVF is poor and not significantly different from patients with reduced LVF. But it's very difficult to tell how the condition will progress on an individual basis. They are used in patients with a low cardiac output , for example, due to acute heart failure, recent myocardial infarction or following heart surgery. Article created:. We prospectively evaluated patients hospitalized with a definite clinical diagnosis of HF. These findings support the poor prognosis of patients with heart failure and preserved LVF and strengthen the need to find ways to improve prognosis in this common syndrome. Last revised:. It usually happens because the heart has become too weak or stiff. Patients with severe pulmonary oedema or cardiogenic shock may require admission to the high dependency unit or intensive care unit. Find encouragement. Outcome of heart failure with preserved ejection fraction in a population-based study.

Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action.

Complications Left heart failure can be complicated with severe volume overload leading to respiratory distress and anasarca as well as arrhythmias tachyarrhythmias or bradyarrhythmias , cardiogenic shock due to pump failure and death. Diabetes, smoking, obesity, male gender, and a sedentary lifestyle are also considered risk factors. Risk factors for heart failure: a population-based case-control study. Limitations of this study: We delineated patients with preserved versus reduced LVF based on qualitative echocardiographical data and not on LV ejection fraction. Low blood pressure and rapid heart rate can occur in severely decompensated failure due to decreased cardiac output. Conditions that can lead to heart failure include: coronary heart disease — where the arteries that supply blood to the heart become clogged up with fatty substances atherosclerosis , which may cause angina or a heart attack high blood pressure — this can put extra strain on the heart, which over time can lead to heart failure conditions affecting the heart muscle cardiomyopathy heart rhythm problems arrhythmias , such as atrial fibrillation damage or other problems with the heart valves congenital heart disease — birth defects that affect the normal workings of the heart Sometimes obesity , anaemia , drinking too much alcohol, an overactive thyroid or high pressure in the lungs pulmonary hypertension can also lead to heart failure. The epidemiology of heart failure: the Framingham Study. These patients also had less ischemic heart disease. As blood flow out of the heart slows, blood returning to the heart through the veins backs up. They also have more hypertension and atrial fibrillation [3] , [9] but have less ischemic heart disease [11] , [12].
