Clinical Manifestations of Myocardial Infarction
Clinical Manifestations of Myocardial Infarction
Pain
Laboratory examination Examination of cardiac enzymes :
ECG ECG changes that occur in the early phase of T wave height and symmetrical. After this there is ST segment elevation. Changes that occur later are the presence of a wave of Q / QS which indicate the presence of necrosis.
Pain scores according to White:
Pain
- Chest pain that occurs suddenly and constantly not subside, usually above the sternal region and upper abdomen, this is the main symptom.
- The severity of pain can increase settled until unbearable pain.
- Pain is very ill, such as punctured-pin that can spread to the shoulder and continued down to the arm (usually the left arm).

- Patients with diabetes mellitus will not experience severe pain because of neuropathy that accompany diabetes can interfere neuroreseptor (collect the experience of pain).
Laboratory examination Examination of cardiac enzymes :
- CPK-MB/CPK
Isoenzymes found in heart muscle increased by between 4-6 hours, peaks in 12-24 hours, returned to normal within 36-48 hours. - LDH / HBDH
Increases in the 12-24 hour time-consuming dams to return to normal - AST
Increases (less real / special) occurred within 6-12 hours, culminating in 24 hours, returning to normal within 3 or 4 days
ECG ECG changes that occur in the early phase of T wave height and symmetrical. After this there is ST segment elevation. Changes that occur later are the presence of a wave of Q / QS which indicate the presence of necrosis.
Pain scores according to White:
- = Do not experience pain
- = Pain on one side without disturbing activities
- = More pain at one place and resulted in disruption of activities, such as difficulty getting out of bed, hard to bend the head and others.
