Typical symptoms of insufficient cardiovascular blood supply include chest tightness, shortness of breath, chest pain, palpitations, pallor, and sweating. The treatment of cardiovascular insufficiency is categorized into medication and surgery depending on the degree of insufficiency. Insufficient blood supply to the heart will affect the normal function of the heart, which will trigger palpitations as well as angina and other obvious symptoms. If angina pectoris occurs, then nitroglycerin or fast-acting heart pills should be taken under the tongue. If nitroglycerin is ineffective, and there is even profuse sweating and obvious chest pain, myocardial infarction is diagnosed after examination, and thrombolytic and surgical treatments need to be carried out in a timely manner. If the above symptoms occur, it is recommended to go to the hospital in time for early and regular treatment.
