HEART FAILURE

Definition:-

Heart failure  is a complex clinical syndrome that can be caused by any heart disease that disrupts the ability of the ventricle to deliver sufficient quantities of blood to the metabolic tissues during normal activities or rest.  The former condition is called “congestive heart failure”, a condition characterized by edematous edema usually caused by fluid backup.  Exercise is the limit of tolerance and fluid retention.  Fluid retention may lead to pulmonary and peripheral edema. Recently, the term “heart failure” has been used to more accurately reflect the clinical syndrome.

SYMPTOMS:

∗Dyspnea, particularly on exertion

∗Orthopnea

∗Paroxysmal nocturnal dyspnea

∗Exercise intolerance

∗Tachypnea

∗Cough

∗Fatigue

∗Hemoptysis

∗Abdominal pain

∗Anorexia

∗Nausea

∗Mental status changes




SIGNS:-

∗Pulmonary edema

∗Pleural effusion

∗Cheyne-Stokes respiration

∗Tachycardia

∗Cardiomegaly

∗Peripheral edema

∗Jugular venous distension

∗Hepatojugular reflux

∗Hepatomegaly

Heart Failure Occurrence in the U.S.

»Around 5 million Americans have heart failure, with an extra 550,000 cases diagnosed each year.

»The prevalence of heart failure pairs with each time of life and affects nearly 10% of those over age 75.

»Heart failure is the most public hospital discharge diagnosis in persons over age 65.

»Although the mortality rates have declined over the last 50 years, the overall 5-year survival remains around 50% for all patients with a diagnosis of heart dissatisfaction with death increasing with side effect significance.

 Age and Gender:-

»For heart failure patients under age 65% of men and 70% of women will die within 8 years.

»Death is classified as sudden in about 40% of patients,1−3 implicating serious ventricular arrhythmias as the underlying cause of death in many patients with heart failure.

»Predominance is more prominent in guys than in females in patients matured 40 75 years.

»No gender predilection is noted among patients older than 75 years.

 Etiology:

»Heart dissatisfaction can effect from any misunderstanding that effects the capability of the heart to contract and relax common causes of heart failure are shown in Systolic heart failure is the classic, more familiar form of the disorder, but current estimates suggest that 20% – 50%of patients with heart failure have conserved left ventricular systolic purpose and feel pain from diastolic dysfunction.

»Rather than systolic heart disappointment that is normally brought about by past myocardial localized necrosis, patients with diastolic heart failure typically are elderly, female, and have hypertension and diabetes.

»However, systolic and diastolic dysfunction frequently coexist. the basic cardiovascular ailments, for example, mi and hypertension can cause both systolic and diastolic brokenness along these lines numerous patients have heart disappointment because of reduced myocardial contractility and abnormal ventricular filling.

»Coronary supply route illness is the most widely recognized reason for systolic heart disappointment representing almost 70% of cases.

»MI leads to a reduction in muscle mass owing to death of affected myocardial cells. how much contractility is hindered will rely upon the size of the localized necrosis.

»while trying to keep up heart yield the enduring myocardium experiences a compensatory rebuilding in this way starting the maladaptive procedure that starts the heart failure syndrome.

Causes:-

Systolic Dysfunction 

Decreased in muscle mass

»Dilated cardiomyopathies

»Ventricular hypertrophy

»Volume overload

Diastolic Dysfunction

»Increased ventricular stiffness

»Ventricular hypertrophy

»Infiltrative myocardial diseases

»Myocardial ischemia and infarction

»Mitral or tricuspid valve stenosis

»Pericardial disease

Low-output versus high-output failure:

»Low-Output failure:- metabolic demands are within normal limits, if the heart does not meet them, failure is referred to as low output (the most common type).

»High-output failure:- If the inflammatory demands increase (e.g., hyperthyroidism, anemia) and the heart is unable to meet them, failure is cited as a high product. Correction of the root cause of high-output failure is important for early treatment, as compared to low-output failure.



Risk factors:

»High blood pressure

»Diabetes

»Coronary artery disease

»Herat attack

»Sleep apnea

»Congestive heart failure

»Alcohol –Drinking

»Obesity

Complications/Intricacies:-

»Heart valve issues:- The valves of your heart, which keep blood streaming the best possible way through your heart, may not work appropriately if your heart is augmented or if the weight in your heart is high because of heart disappointment.

»Kidney harm or disappointment:- Heart disappointment can lessen the blood stream to your kidneys, which can in the end cause kidney disappointment whenever left untreated. Kidney harm from heart disappointment can require dialysis for treatment.

»Liver harm:- Heart disappointment can prompt a development of liquid that puts a lot of weight on the liver. This liquid reinforcement can prompt scarring, which makes it increasingly hard for your liver to work appropriately.

»Heart beat issues:- Heart musicality issues (arrhythmias) can be a potential complexity of heart disappointment.

Heart failure Types:

»Left – Side Heart failure:- If blood cannot be adequately pumped from the left ventricle to the peripheral circulation and it accumulates within the left ventricle, the patient is likely to exhibit signs of left -sided HF.

As the fluid portion of the blood backs up into the pulmonary alveoli, the result is the development of pulmonary edema that can present as shortness of breath, dyspnea on exertion, and a third heart sound.

»Right-sided failure:- At the point when blood isn’t siphoned from the correct ventricle, the liquid segment Of the blood backs up throughout the body (e.g., in the veins, liver, legs, bowels), producing systemic edema.

Such signs would include evidence of elevated pressures in the venous system.

»Diastolic dysfunction:- Diastolic dysfunction refers to an inability for the ventricles to fill with blood during diastole, or ventricular relaxation.

Under normal circumstances, blood returns to the right side of the heart from either the upper and lower body (superior vena cava and inferior vena cava, respectively) or left side of the heart from the lungs (via the pulmonary vein, left atria, and mitral valve).

An inability for the respective ventricle(s) to accommodate the blood that is returning to it will result in a backup of blood in those areas where it originated from.

»Systolic dysfunction:- refers to an impaired degree of ventricular contraction resulting in a decrease in cardiac inotropy (contractility) and cardiac stroke volume.

This sets in motion a series of compensatory mechanisms with the purpose being to increase the ability of the heart to deliver blood to the body (increase stroke volume) but which have a negative effect by increasing plasma volume (preload) and pulmonary capillary wedge pressure.

Patients with systolic dysfunction, unlike those with diastolic dysfunction, have lower than normal cardiac ejection fractions due to stroke volume reductions along with increases in end diastolic volumes.

STAGES OF HEART FAILURE:-

Heart failure stages

Image source: Heart failure Stages

»The rules center around four phases in the improvement of heart failure: organizes An and B incorporate patients in danger” for heart failure, and stages C and D include patients who have developed heart failure.

»Each of the four stages of heart failure is associated with select treatment strategies and recommendations, which will be included in the following sections.

»Treatment of patients with refractory end-stage HF (stage D) should include the primary therapeutic agents that are used for stages A, B, and C.

»However, lack of an acceptable response will require specialized non-pharmacologic modalities, such as mechanical circulatory support, transplantation, and end-of-life care for those exhibiting no benefit.

PATHOPHYSIOLOGY:-

To recognize the pathophysiologic procedures in heart failure, a simple

Considerate of normal cardiac function is essential. Cardiac output

(CO) is definite as the capacity of blood emitted per unit time (L/min)

heart rate (HR) And stroke volume (SV):

CO = HR × SV

The association among CO and mean arterial pressure (MAP) is

MAP = CO × systemic vascular resistance (SVR)

Heart rate is measured by the autonomic nervous structure. Stroke volume, or the volume of blood expelled throughout systole, be contingent on preload, afterload, and contractility.
