43 years old blood pressure high pressure 80mmHg low pressure 60mmHg may be hypothyroidism, heart failure, myocardial infarction and other causes, can be supplemented by levothyroxine, digitalis, coronary stenting and other treatments. 1. Hypothyroidism: hypothyroid patients have insufficient secretion of thyroxine, the body is in a low metabolic state, resulting in a drop in blood pressure, which can lead to high pressure of 80mmHg and low pressure of 60mmHg, and can be treated by exogenous supplementation of levothyroxine. 2. Heart failure: heart failure leads to heart pumping function decreases, which leads to blood pressure drop, resulting in high pressure 80mmHg low pressure 60mmHg situation, can be oral digitalis, furosemide and other drugs, there are indications for the installation of pacemaker treatment. 3. Myocardial infarction: myocardial infarction leads to a decrease in myocardial contractility, causing cardiogenic shock, resulting in high pressure 80mmHg low pressure 60mmHg, should be timely use of urokinase, streptokinase and other thrombolytic agent treatment or timely coronary stent implantation. 43 years old blood pressure high pressure 80mmHg low pressure 60mmHg should go to the hospital in time to improve the examination, give targeted treatment after the cause is clear.
