The term heart failure refers to the sudden and complete cessation of heart activity. However, in reality, heart activity does not stop suddenly. Heart failure occurs slowly, often over a period of years, when the heart is unable to work efficiently. This is why many patients do not realize that they have the condition, but the heart has already started to fail and the symptoms have been present for many years. The severity of the condition depends on how much of the heart’s pumping capacity is lost. The Department of Cardiothoracic Surgery at Wuhan Union Medical College Hospital will provide you with further knowledge related to the causes of heart failure, in the hope that it will help you understand heart failure. Wuhan Union Hospital cardiothoracic surgery Hong Hao etiology is the same but the composition of the ratio is different: in the clinic, can lead to young people heart failure causes, can also cause heart failure in the elderly, such as coronary heart disease, cardiomyopathy, high heart disease, pulmonary heart disease, shock and severe anemia and so on. However, the etiologic composition ratio is different. Heart failure in the elderly is more common in coronary heart disease (1/3), hypertensive heart disease (1/4) and pulmonary heart disease (1/10). Age-specific heart disease: The rate of patients with age-specific heart disease such as degenerative heart valve disease, conduction tract degeneration and cardiac amyloidosis in the elderly and the degree of myocardial damage increase with age, which is a cause of heart failure in the elderly that cannot be ignored. Multiple etiologic factors coexist: Heart failure in the elderly can be the result of the combined effects of two or more types of heart disease. One of them is the main cause of heart failure, the other is synergistic and aggravate the degree of heart failure research, make the condition complicated, in the elderly heart failure, two or more kinds of heart disease coexist prevalence can be as high as 65%, to coronary heart disease with pulmonary heart disease, high heart disease with care disease common. Triggers are the same, but the degree is different: the triggers of heart failure in the elderly are not different from those in young and middle-aged patients, and are often infection (especially respiratory infection) and acute myocardial ischemia, followed by tachyarrhythmia (rapid atrial fibrillation, paroxysmal supraventricular tachycardia) and again inhibitory myocardial medication, blood transfusion, fluid transfusion, exertion, agitation, hypertension, renal failure and pulmonary embolism. However, there is a difference in the degree of triggers. Due to poor cardiac reserve function and relatively heavy heart disease in the elderly, heart failure can be induced by loads that are irrelevant in young and middle-aged patients than in young and middle-aged patients. In addition, pulmonary embolism-induced heart failure is relatively common in the elderly. The above is a general introduction to heart failure, I hope you can get the knowledge you need from it, Wuhan Union Hospital cardiothoracic surgery experts remind you that although heart failure occurs more often in elderly patients, but the disease is accumulated over time, so it should be prevented from young adults.
