Cardiac capillary blockage generally does not require stent implantation because the capillaries are too thin for stenting, and is usually treated with medication or thrombolytic therapy.
Cardiac capillary blockage will cause cardiac microcirculation disorder, which will lead to chest tightness, chest pain and other symptoms of myocardial ischemia. Generally, because the capillaries are too fine, when microcirculation disorder occurs, stent implantation is generally not possible because the diameter of the thinnest stent is about 2.25mm. Mostly drug therapy is taken, including anti-platelet aggregators such as aspirin, lipid regulators such as atorvastatin, metoprolol to improve ischemia, and nicorandil to improve microcirculation.
Cardiac stents and bypass grafts generally address lesions of the main coronary arteries and their major branches, such as the anterior descending branches, gyratory branches, and other large vessels with severe stenosis. The trunk of the coronary artery is the main blood vessel supplying the heart’s blood supply, and the capillaries belong to the periphery, and microcirculation disorders are mostly treated with medication.
If the patient has heart capillary blockage, it is recommended to go to the hospital in time for coronary angiography and other tests to assess the specific conditions of the coronary arteries, and measure the microcirculation resistance index if necessary, and then treat reasonably under the guidance of the doctor.
