What is the clinical manifestations of coronary heart disease

Patients with coronary heart disease due to the age, sex, physical condition, the sensitivity of the illness and the extent of progress in the establishment of the collateral circulation differences so that the clinical manifestations are vastly different, and varied. Initially, patients can no symptoms or discomfort, occasional body was found in the investigation, there are ischemic electrocardiographic changes, suggesting that patients suffering from the "occult coronary heart disease", or the existence of "silent myocardial ischemia," and they should heighten their vigilance and regular inspection, and to give a positive control. If coronary atherosclerotic lesions further development of luminal stenosis ≥ 75%, myocardial blood supply can be seriously affected in case of angina. Most of the sternum performance for the attack before or after the heart-squeezing or pain austerity kind to the left shoulder, left arm, left hand refers to the medial radiotherapy. But some angina in the chest, or for the performance headache, toothache, throat tightness, or for the performance of upper abdominal pain or discomfort, and some separate performance for etc., and often needs and the discomfort caused by the corresponding organs of identification. Some of the elderly, particularly in patients with diabetes, chest tightness or only showed symptoms of breathing difficulties, chest pain not occur, even such acute myocardial infarction no chest pain symptoms (that is painless myocardial infarction), often to shock as the main clinical manifestations and treatment. Angina most common predisposing factor is the physical activity and emotional. Road urgency like walking up stairs or uphill, the chest pain is the most typical exertional angina, and serious cases, shower or dry shaving themselves after such activities can be induced angina. Emotional such as anger, anxiety, watch sports competitions and so fierce, can cause angina. However, some studies indicate that induced by emotional angina often below the threshold of the campaign angina or manual threshold, it may also speculate that sympathetic nerve-mediated vasoconstriction factors participation. A meal-induced angina is another common factor, the factor alone induced, can be found in a similar situation will be after. The majority of patients every incentive to attack, symptoms similar, but with the progress of disease, aggravated sexual trends. Some patients, angina and myocardial oxygen consumption attack unrelated, often supine occurred in a quiet state, such as in patients with sudden onset of sleep at night, forced to to achieve remission, but also occurred in the daytime morning or lying, that is, supine angina, indicating patients with multivessel coronary artery with serious resistance Cypriot disease, high incidence of myocardial infarction. In some patients with angina attack when breathing difficulties, heart palpitations, nausea, sweating, dizziness and looking pale, and even loss of consciousness, and so on. If the coronary blood flow by the sudden interruption of acute myocardial infarction, chest pain more intense, longer duration, containing nitroglycerin invalid. Some patients with coronary heart disease, the onset of chest pain, only to various types of performance arrhythmia, coronary angiography that unless the presence of coronary artery stenosis, or the diagnosis of coronary heart disease is conjectural in nature. Over 40 years old in the elderly, if the above, the treatment must be promptly to the hospital, your doctor will carry out the necessary checks to clear diagnosis of patients with coronary heart disease has been diagnosed, the risk factor intervention in the meantime, we should try to avoid inducing factors have, and regularly to the hospital to review, under the guidance of a doctor in establishing a reasonable rehabilitation programs. In addition, a growing number of patients with sudden cardiac death from coronary heart disease caused more than half of the Western countries statistical information that can be as high as 80 percent. Many of these patients age is not too large, the patient can be with or without the past history of heart disease, before the onset often without any symptoms or not, few can cause the patient or doctor's attention. So, to really understand coronary heart disease, doctors still faced with many pressing problems.
