When coronary artery blood flow is too slow, it is necessary to improve the examination to clarify the cause of the disease, and according to the cause of the disease and the condition, medication, stent implantation, surgical treatment and so on. Slow coronary blood flow may be caused by hyperlipidemia or long-term high blood pressure, which is often accompanied by atherosclerosis of coronary arteries and narrowing of blood vessels, affecting blood flow. Slow blood flow may also be caused by vascular malformations. Coronary CT or coronary angiography is recommended for a clear diagnosis. If accompanied by chronic diseases such as hyperlipidemia and hypertension, it is recommended to actively medicate with statins such as atorvastatin to lower blood lipids and antihypertensive drugs such as valsartan to control blood pressure. If the stenosis of blood vessel is more than 75%, it is recommended to take stent implantation to expand blood vessel to avoid myocardial infarction. Coronary artery bradycardia caused by vascular malformation requires surgical treatment, with coronary interventional stenting being the most common, and patients with complicated conditions need to consider coronary artery bypass grafting or even open-heart direct vision surgery for treatment. If the coronary microcirculatory lesions caused by slow blood flow, common x syndrome, this situation requires coronary angiography to clarify. In short, when the coronary artery blood flow is too slow, it is recommended to go to the hospital cardiology department as soon as possible, under the guidance of the doctor to improve the examination, active treatment, so as not to delay the condition.
