How early diagnosis of acute myocardial infarction Health?

Acute myocardial infarction is common in the elderly acute, if early diagnosis, to reduce mortality is of great significance.
Elderly patients with acute myocardial infarction early performance: the original angina patients with coronary heart disease, angina pectoris nature (time, frequency, etc.) have increased performance for more than 15 minutes, application of nitroglycerin void; sudden severe heart attack Colic, before exertion disease, alcoholism and mental trauma, such as incentives; lasting or recurrent angina at night; usually healthy, or hidden coronary heart disease; convalescent suddenly appeared in myocardial infarction severe angina pectoris; heart cutter pain accompanied by nausea and vomiting, arrhythmias, blood pressure drop, or cardiac insufficiency, etc..
Acute myocardial infarction, typical clinical symptoms is not difficult to identify, most notable for the performance of the former District into the heart of substernal pain, and more pain for strangulating-performance, tightening like pressure, accompanied by nausea, vomiting, continuing a long time and are generally more than 15 minutes, including nitroglycerin rest can be alleviated, if there hyperlipidemia diabetes, hypertension and other diseases, in particular, to guard against the possibility of acute myocardial infarction.
In elderly patients with acute myocardial infarction symptoms not typical, and not without pain or severe pain patients should pay attention to the following circumstances: Where the patients over 40 years of age, for reasons unknown in the wet hill, weak pulse, blood pressure was pale decline shock performance, should consider the possibility of acute myocardial infarction; elderly patients, sudden difficulty in breathing, cyanosis, respiratory sit, 1,10 pink bubble sputum, such as heart failure or performance of hemoptysis, or serious arrhythmia no other reason can be found , acute myocardial infarction should also consider the possibility of blood pressure in hypertensive patients suddenly dropped significantly, especially at the same time with congestive heart failure, acute myocardial infarction should also think of the possibility.
Suspected acute myocardial infarction patients, we should do so promptly ECG examination, and follow the observation and attention to the contrast can be made if the leukocyte count and classification, ESR, aspartate aminotransferase, lactate dehydrogenase, creatine phosphokinase, such as inspection of the early diagnosis of acute AMI more useful.
