MindMap Gallery acute coronary syndrome
The definition, types, causes and laboratory tests of ACS are introduced. Acute coronary syndrome refers to a group of clinical syndromes related to acute myocardial ischemia caused by the rupture of unstable plaques in the coronary arteries leading to thrombosis, embolism or spasm, causing complete or incomplete occlusion of the coronary arteries.

When you stop looking for yourself, you will find the entire universe because what you are looking for is also looking for you. Anything you do persevere every day can open a door to the depths of your spirit. In silence, I slipped into the secret realm, and I enjoyed everything to observe the magic around me, and didn't make any noise. Why do you like to crawl when you are born with wings? The soul has its own ears and can hear things that the mind cannot understand. Seek inward for the answer to everything, everything in the universe is in you. Lovers do not end up meeting somewhere, and there is no parting in this world. A wound is where light enters your heart.
Chronic heart failure is not just a problem of the speed of heart rate! It is caused by the decrease in myocardial contraction and diastolic function, which leads to insufficient cardiac output, which in turn causes congestion in the pulmonary circulation and congestion in the systemic circulation. From causes, inducement to compensation mechanisms, the pathophysiological processes of heart failure are complex and diverse. By controlling edema, reducing the heart's front and afterload, improving cardiac comfort function, and preventing and treating basic causes, we can effectively respond to this challenge. Only by understanding the mechanisms and clinical manifestations of heart failure and mastering prevention and treatment strategies can we better protect heart health.
Ischemia-reperfusion injury is a phenomenon that cellular function and metabolic disorders and structural damage will worsen after organs or tissues restore blood supply. Its main mechanisms include increased free radical generation, calcium overload, and the role of microvascular and leukocytes. The heart and brain are common damaged organs, manifested as changes in myocardial metabolism and ultrastructural changes, decreased cardiac function, etc. Prevention and control measures include removing free radicals, reducing calcium overload, improving metabolism and controlling reperfusion conditions, such as low sodium, low temperature, low pressure, etc. Understanding these mechanisms can help develop effective treatment options and alleviate ischemic injury.

acute coronary syndrome
definition
A group of clinical syndromes caused by acute myocardial ischemia
type
Unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI)
Cause
Atherosclerosis is a major causative factor
Including inflammatory response, endothelial dysfunction and platelet activation, etc.
Risk factors such as hypertension, hyperlipidemia, smoking, and diabetes also increase the risk of acute coronary syndrome
These factors can lead to endothelial dysfunction and plaque formation
Mental stress and emotional changes may also induce acute coronary syndrome
Stress causes neuroendocrine changes that affect the cardiovascular system
diagnosis
A detailed history and physical examination are the first steps in diagnosis
Electrocardiogram (ECG)
Abnormal manifestations such as ST segment elevation or depression, T wave inversion, etc. suggest myocardial ischemia or infarction.
blood biochemistry test
Blood routine
24 to 48 hours after onset of symptoms, white blood cells increase
Neutrophilia
Eosinophils decrease and disappear
Increased erythrocyte sedimentation rate
Increased C-reactive protein (CRP)
Elevated markers of myocardial injury
Mb
CK
CK-MB
cTn
Changes in coagulation status
Elevated fibrinogen and D-dimer may lead to thrombosis
Imaging tests such as echocardiography and coronary angiography, which are the “gold standard” for diagnosing acute coronary syndromes, help assess the degree of arterial stenosis.
Assess patient response using treatments such as platelet inhibitors, anticoagulants, and analgesia
