Several types of heart failure

Heart failure is a condition in which the heart fails to function normally. Those with existing cardiovascular disease and older age are more likely to develop heart failure. Heart failure has gradually attracted everyone's attention in today's society. Medicine divides heart failure into several types based on some specific factors. Let's take a look at the types of heart failure and how they are classified.

Heart failure is a syndrome that is difficult to define precisely. The most widely accepted definition at present is that heart failure refers to a pathophysiological state in which the heart cannot maintain sufficient cardiac output to meet the metabolic needs of tissues due to abnormal heart function. It is the terminal state of cardiovascular disease, and its incidence and prevalence increase with age. With the aging of the population, heart failure has become a major health and socioeconomic problem.

Different criteria can be used to distinguish the types of heart failure. Classifying heart failure into different types helps to more specifically target treatment measures. ?Next, I will introduce it to you.

According to the speed of onset and development, heart failure can be divided into acute heart failure (including acute pulmonary edema and shock) and chronic heart failure.

According to the location of heart failure, the types of heart failure include left heart failure, right heart failure and total heart failure. The pathological changes of left heart failure are pulmonary circulation congestion, pulmonary edema and tissue hypoperfusion. The pathological changes of right heart failure are obstruction of systemic venous return and organ congestion. The pathological changes of total heart failure are congestion in the venous system and insufficient blood supply to the arterial system, and it also exhibits the characteristics of bilateral heart failure.

According to the cardiac output during heart failure, it can be divided into high cardiac output type and low cardiac output type. In high-output heart failure, resting cardiac output is greater than usual, but still less than before heart failure occurred. Low cardiac output heart failure is caused by decreased cardiac output due to impaired myocardial systolic and diastolic function or cardiac integration dysfunction.

According to the systolic and diastolic function of the heart during heart failure, it can be divided into systolic heart failure, diastolic heart failure and mixed heart failure. In systolic heart failure, the heart cannot contract properly and cardiac output is reduced. Diastolic dysfunction heart failure is characterized by decreased ventricular active relaxation function and increased ventricular stiffness, insufficient filling, and reduced cardiac output. Mixed heart failure has both systolic and diastolic dysfunction.

Depending on whether heart failure has clinical symptoms, it can be divided into subclinical heart failure and clinical heart failure. Subclinical heart failure, also known as latent or asymptomatic heart failure, is a condition in which the patient's heart function has declined and hemodynamics are abnormal, but there are no clinical manifestations. Clinical heart failure will have symptoms and signs of heart failure.

The above content is all about some introductions to the types of heart failure. Heart failure is temporarily classified according to the methods mentioned above. I believe that after reading this, you will have a full understanding of the types of heart failure. I hope my story can help and be useful to you.
