Table 1 Differences in clinical presentation and risk factors between TC and AMI
TC | AMI | |
|---|---|---|
1.Clinical presentation | ||
Symptoms | Chest pain, dyspnea (acute heart failure, pulmonary edema)—most common symptoms Syncope Palpitations: arrhythmias (ventricular fibrillation—uncommon) Asymptomatic | Chest pain Dyspnea (acute heart failure, pulmonary edema) Syncope Palpitations: arrhythmias (ventricular arrhythmias: monomorphic/polymorphic ventricular tachycardia, ventricular fibrillation) |
Signs Systolic murmur | Mitral regurgitation Dynamic LVOTO/LV intraventricular obstruction LV free wall rupture | Mitral regurgitation LV free wall rupture |
Pulmonary crackles | Acute heart failure/edema pulmonary | Acute heart failure/Oedema pulmonary |
Hypotension/hemodynamic instability | Cardiogenic shock—uncommon Life-threatening arrhythmias Cardiac arrest—rare | Cardiogenic shock Life-threatening arrhythmias Cardiac arrest |
2.Risk factors | ||
Cardiovascular risk factors | Usually absent | Smoking, HT, dyslipidemia, diabetes mellitus, obesity |
Sex | Women> men | Men> women |
Age | elderly, post-menopausal women | Elderly |
