Cardiovascular disease caused by the “three highs” (hypertension, hyperlipidemia, and hyperglycemia) is the number one killer of the health of the elderly. Some patients are very insidious and have coronary stenosis or coronary artery stenosis without any clinical symptoms. Heart dysfunction. How to detect such cardiovascular disease as early as possible? Zhou Jie, deputy chief physician of the Imaging Department of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, suggested cardiac imaging examination.
For example, color Doppler ultrasound can dynamically display the structure of the heart cavity, heart beat and blood flow. Is normal, but can not show coronary artery disease and myocardial damage.
Coronary CT examination is currently the most widely used in the cardiovascular system, which can display the internal structure of the heart. People with “three highs” can check whether they are complicated with atherosclerosis, judge the condition of atherosclerotic plaques, distinguish which plaques are stable and which are unstable, and also measure the degree of coronary stenosis to assess whether they meet the diagnostic criteria for coronary heart disease. . However, the radiation dose of CT examination is relatively high, and the examination of cardiac function is limited, which is inferior to cardiac color Doppler ultrasound and cardiac magnetic resonance.
Cardiac magnetic resonance examination has good soft tissue resolution ability, which can clearly display the internal structure of the heart, analyze the subtle changes of myocardial soft tissue, and early detect myocardial damage caused by “three highs” through multi-parameter and multi-sequence imaging. At the same time, it can display the heart movement, more accurately assess the systolic and diastolic function of the heart, and screen out early cardiac insufficiency. However, this examination takes about 40 minutes at a time, and the display of coronary arteries is still not as good as CT.
Zhou Jie suggested that people with “three highs” should use the above inspection methods reasonably as soon as possible to detect coronary atherosclerosis or myocardial damage caused by “three highs” as soon as possible. Taking appropriate measures in time to control the development of the disease can delay or avoid the occurrence of adverse cardiovascular events.
