PHYSICAL EXAMINATIONVital Signs:
BP:135/95 mmHgHR:92 beats/minute (regular rhythm and volume)RR: 22 breaths/minute
General examination- obese

Cardiovascular system• Inspection: On inspection, there is no deformity, no dilated vein, no surgical
scar, and no visible pulsation.
• Palpation:The apex beat is not palpable. There was no parasternal heave. Thrills were also absent.
• Auscultation:S1 and S2 were heard. There was no radiation, no murmur, no rubs and no additional sounds. S3 and S4 were not heard. There was no carotid bruit present. The 1st and 2nd maneuver (mitral stenosis and aortic regurgitation) reveals no significants findings.

Provisional diagnosis• Non ST elevation myocardial infarction (NSTEMI) / unstable angina
History :
- Central chest tightness :Radiated to jaw & left arm20 minutes Relieved by GTNAssociated with : nausea, sweating, dyspnoea
- Known case of DM & HT ( 10 years )- +ve family hx of heart problem- Smoker ( 20 years)- fat food diet
PE : -obese

Differential Diagnosis
1. Acute myocardial infarctionPoints to support : Points to against :ECG : ST segment depressionRelieved by GTNDuration : 20 minutes
2. Aortic dissectionPoints to support : severe, sudden chest pain History of HT & DMPoints to against : Chest Pain : tightness, not radiate to the back No syncope CXR : no boarding of upper mediasternal & distortion of aortic knuckle, no right
sided pleural effusion & left ventricular hypertrophy

• Pulmonary embolism– Pros :chest pain associated with shortness
of breath– Cons :no hemoptysis and no risk factor of
hyper-coagulability like prolong bedrest.
• Pericarditis – Pros :the patient present with chest pain– Cons :the pain not aggravated by changes in
posture like leaning forward.

investigationGeneral :
FBC, BUSE : no significant findingPT, PTT : normalCXR : normal ( No cardiomegaly, perihilar
haziness and lung fields were clear)

Final diagnosis• Non ST elevation myocardial
infarction (NSTEMI)
• Points to support :
- Central chest tightness :Radiated to jaw & left arm20 minutes Relieved by GTNAssociated with : nausea, sweating, dyspnoea

Criteria for high & low for death or MI
High risk• ECG abnormalities
- Dynamic ST segment changes > 0.05 mV, particularly ST segment depression
- Transient ST segment elevation- T wave inversion > 0.2 mV- Pathological Q wave- Bundle branch block- Sustain Ventricular tachycardia
• Elevated Troponin level
Low Risk• No recurrence of chest pain
within the observational period• No ST segment depression or
elevation but rather negative T wave, flat T wave or normal ECG
• Without elevation of Troponin or other biomarker of cardiac injury

High Risk Low risk

Management
• Post hospitalization
- Medical therapy ( compliance )- Life-style modification: Diet : highly oily fish, fruit, vegetable, fiber & low fats: Exercise : Regular daily exercise: Avoid air travel for 2 months: Reduce & stop smoking- Follow up ( after 3 & 5 weeks )
