Hypertrophic cardiomyopathy refers to the concentric thickening of idiopathic cardiomyopathy, which leads to myocardial sclerosis and decreased diastolic function. It is an obstructive heart disease caused by abnormal diastolic function.
Cardiac hypertrophy will lead to limited thickening of the heart wall and hypertrophy of the left ventricle. In early hypertrophic cardiomyopathy, there was no obvious abnormality in the left ventricle, but with the aggravation of myocardial hypertrophy, the volume of the cardiac cavity began to decrease, the pressure of the ventricle increased, and the load of the left atrium gradually increased, leading to dilatation. In the late stage of the disease, the disease often leads to atrial fibrillation and thrombosis.
Second, why do you get hypertrophic cardiomyopathy?
Hypertrophic cardiomyopathy is primary and secondary.
1, primary hypertrophic cardiomyopathy, is generally considered as an autosomal dominant genetic disease, mainly caused by myosin and myosin mutation. At present, it is unclear how many genes act on the pathogenesis of hypertrophic cardiomyopathy. However, studies have shown that hypertrophic cardiomyopathy in Maine cats and bag cats is closely related to gene mutation.
2, secondary hypertrophic cardiomyopathy, this situation can be caused by hyperthyroidism, diabetes, endocrine diseases and other diseases to increase blood pressure, and then secondary hypertrophic cardiomyopathy.
Third, the main symptoms of hypertrophic cardiomyopathy?
Cats with hypertrophic cardiomyopathy may have no symptoms at all when their condition is mild. Cats are often found during regular physical examination or diagnosis of other diseases every year, because doctors will find heart murmurs or beating rhythms when auscultating. The main clinical manifestations of cats with this disease are loss of appetite, weight loss, wheezing, pleural effusion and chylothorax caused by heart failure, which leads to dyspnea.
Hypertrophic cardiomyopathy in cats is gradually developing. At present, there is no medicine that can play a good therapeutic effect. All treatments are aimed at delaying the process of heart failure in cats and preventing complications.
But I hope the shovel officers don't give up because of this! Many cats can still live happily for many years when they are sick.
However, it is necessary for the owner to do daily care for it, and the following aspects should be paid attention to:
1, control the cat's weight and keep the body size standard.
2. Control the sodium intake and don't let the cat eat a high-salt diet.
3. Try to avoid stress reaction.
4. Appropriate supplementation of coenzyme Q 10 and fish oil to the affected cats.
Dr. Paw Paw Tips: Early detection and treatment of hypertrophic cardiomyopathy in cats will do less harm to cats, so it is very important for cats to have regular physical examination, and owners should pay attention to it!
