Myocardial infarction, which is common in the cardiovascular field and which has multiple symptoms, seriously threatens people ‘ s health and lives. And of the many types of myocardial infarction, miNOCA (Myocardial infarction with no obstractive coronary atherosclerosis) i.e. coronary artery non-obstructive myocardial infarction is a more specific but less well-recognized disease of concern. As a senior medical practitioner, today I will introduce to you all knowledge of MNOCA myocardial infarction in terms of cause, clinical performance, assistive examination, treatment and prognosis.
I. ENERGY ANALYSIS
MINOCA’s myocardial infarction is characterized by the fact that, despite acute myocardial infarction symptoms, the coronary aneurysm is not visible. This means that, unlike most acute myocardial infarction caused by the breakdown of coronary porridge, MINOCA ‘ s causes are more complex and varied.
For the time being, researchers believe that possible reasons for MINOCA include:
Coronary artery convulsions: The high responsiveness of coronary artery smoothing muscles to internal or external intensive vascular substances may result in local or extensive vascular convulsions, which may cause myocardial insemination. Microvascular diseases: These include microvascular functional disorders, the takotsobo syndrome (also known as stress myocardiosis) or myocarditis, which can lead to microvascular blockage or functional impairment, leading to a heart attack.
Bleeding dissolved or embolised: In some cases, the embolism within the coronary artery may be spontaneously dissolved or emboldened, while the coronary artery is not captured at this moment, leading to the diagnosis of MINOCA.
4. Coronary artery fractures or strippings: a pathological change such as a spontaneous coronary artery layer may also cause myocardial infarction, but may not be visible at coronary artery.
II. The clinical manifestations of MINOCA myocardial infarction are similar to the traditional myocardial infarction, with most patients suffering from chest pain, short breath and heart attack, some of which may be associated with full-body nausea, vomiting and sweating.
Because MNOCA patients are usually younger and may have fewer traditional cardiovascular risk factors, their clinical performance may be even more unusual, easily neglected or misdiagnosed.
For patients suspected of being MINOCA, a series of supplementary examinations are required to make a clear diagnosis. These inspections include, but are not limited to:
1. EKG: The electrocardiogram is the usual method for the diagnosis of myocardial infarction, and the electrocardiogram of the MNOCA patient may be shown in the form of an ST sector lift, pressure or T-wave change, etc.
Myocardial enzyme examination: After myocardial infarction, myocardial cell necrosis releases myocardial enzyme to blood, e.g. calcium protein, muscular acid enzyme enzyme, etc. By detecting changes in the levels of these enzymes, myocardial infarction can be assessed.
Coronary artery pulsation: Although coronary artery pulsation may not have been visible in MINOCA patients, it is an important means of excluding coronary artery inhibition and is one of the necessary conditions for the diagnosis of MINOCA.
4. Other visual examinations: CMR, OCT, etc., which help to detect coronary vascular microvascular pathologies, cardiac lesions and cardiac abnormalities.
IV. The treatment strategy for MINOCA myocardial infarction includes, inter alia, drug treatment and lifestyle adjustment. In the area of drug treatment, it may include:
1. Anti-sculpable tablets, such as aspirin, for use in preventing the formation of blood clots.
2. Anticondensants: In specific cases, anticondensed drugs may be needed to reduce the risk of haematosis.
3. Plasma-reducing drugs, such as tatin-type drugs, used to regulate blood resin levels and to reduce the occurrence of sclerosis of arteries.
4. Other drugs, such as beta receptor retardants, calcium route retardants, etc., used to improve myocardial blood supply and reduce heart burden. 5. General treatment: cessation of smoking, alcohol limitation, balanced diet, adequate exercise, pleasure and drug dependence.
V. The prognosis for the prognosis of MINOCA myocardial infarction varies from one individual to another. In comparison with patients with obstructive coronary disease (MI-CAD), MINOCA patients are usually younger and have fewer theoretical complications, but this is due to the relatively low level of knowledge about him and the sometimes delayed treatment, which leads to less effective treatment. At the same time, MINOCA patients are at risk of re-emergence and have a higher incidence of non-heart death. Therefore, active search for causes, targeted treatment and enhanced secondary prevention are essential for persons with MINOCA.
In conclusion, miNOCA myocardial infarction is a special and important heart disease. Understanding its causes, clinical performance, assistive examinations and treatment strategies is important to improve the diagnostic accuracy and treatment effectiveness of MINOCA.
At the same time, strengthening health education and lifestyle interventions are also key measures to prevent the occurrence and recurrence of MINOCA. It is hoped that this article will help you to better understand and understand the particular disease of the minoca myocardial infarction.
