The left ventricle supplies most of the heart's pumping power, so it's larger than the other chambers and essential for normal function.

Heart failure HF is a major worldwide public health problem. One in five persons aged 40 years in the United States will develop HF during their lifetime 1 and HF remains the leading cause for hospitalization among the elderly 2. While age and sex-specific HF incidence is not increasing 3 , overall HF survival has improved and the number of persons over age 65 is rapidly increasing. Thus, the absolute number of patients with HF will continue to increase. Resource utilization associated with HF is high in both the inpatient and outpatient settings, regardless of EF. HF is a syndrome that can be defined clinically by a collection of symptoms dyspnea, fatigue, exertional intolerance and signs edema, gallop, rales that are attributable to a cardiac disorder 2. HF may also be defined hemodynamically, by an inability to provide adequate cardiac output to the body at rest or with exertion, or to do so only in the setting of elevated cardiac filling pressures.

E, peak early filling velocity; A, velocity at atrial contraction; DT, deceleration time; Adur, A duration; ARdur, AR duration; S, systolic forward flow; D, diastolic forward flow; AR, pulmonary venous atrial reversal flow; e', velocity of mitral annulus early diastolic motion; a', velocity of mitral annulus motion with atrial systole; DT, mitral E velocity deceleration time. Ejection fraction as assessed by M-mode echocardiography, quantitative 2-dimensional 2-D echocardiography biplane Simpson and semiquantitative 2-D echocardiography. Yet, the prevalence of diastolic dysfunction and its relation to systolic dysfunction and CHF in the community remain undefined. Subjects without a CHF diagnosis but with diastolic or systolic dysfunction were considered as having either preclinical diastolic or preclinical systolic dysfunction. Overall, CHF was much more common among those with systolic or diastolic dysfunction than in those with normal ventricular function. However, even among those with moderate or severe diastolic or systolic dysfunction, less than half had recognized CHF.

Systolic and Diastolic Heart Failure

Left ventricular diastolic dysfunction is a common finding in critically ill patients. It is characterized by a progressive deterioration of the relaxation and the compliance of the left ventricle. Two-dimensional and Doppler echocardiography is a cornerstone in its diagnosis.. Acute pulmonary edema associated with hypertensive crisis is the most frequent presentation of diastolic dysfunction critically ill patients. Myocardial ischemia, sepsis and weaning failure from mechanical ventilation also may be associated with diastolic dysfunction..

Diastolic dysfunction and diastolic heart failure: Mechanisms and epidemiology

Pathophysiology of heart failure has been considered to be a damaged state of systolic function of the heart followed by a state of low cardiac output that is, systolic heart failure. Even if systolic function is preserved, left ventricular filling in diastole can be impeded and resulted in elevation of filling pressure and symptoms of heart failure. This kind of heart failure is called diastolic heart failure. Nowadays, diastolic heart failure is referred to as heart failure with preserved ejection fraction HFpEF , whereas systolic heart failure is referred to as heart failure with reduced ejection fraction HFrEF. In this paper, the similarities and differences between the pathogenesis and pathophysiology of diastolic and systolic heart failure were reviewed. Although diastolic heart failure is a common condition of heart failure worldwide, its pathophysiology has not been sufficiently elucidated. This is thought to be the most significant reason for a lack of established treatment methods for diastolic heart failure.

Chronic heart failure CHF is the final outcome common to most heart diseases. For a variety of reasons--the aging population, increased survival rate among patients with illnesses such as coronary heart disease or hypertension--the prevalence of CHF has increased. Pharmacological treatment of heart failure has advanced and most clinical trials show improved prognosis but the effects of pharmacological therapy on the general population of patients with CHF have been modest and high rates of mortality and morbidity persist. In these patients, the effect of a range of drugs used in CHF therapy has only recently been evaluated. Chronic heart failure with preserved systolic function is more frequent in older patients and women, 3,6,7 which may partly explain the poor prognosis. In recent years, both epidemiologic and clinical aspects of the problem and its treatment have received much attention and the objective of this paper is to review major results in the literature. Initially, the term used to classify patients with heart failure and normal or nearly normal contractility was "diastolic heart failure.

    Thus it was assumed that since systolic function was "preserved" the problem must lie in diastole, although it is not clear by whom or when this.

    Digitalis should be avoided, except in atrial fibrillation, to control heart rate. Introduction. Chronic heart failure (CHF) is generally associated with a poor prognosis.
