Overview
The prognosis of stress cardiomyopathy is generally excellent, with most patients making a complete recovery within weeks. However, death from complications of heart failure and heart rupture may occur.
Natural History
Provided that patients survive the initial insult without any complications, most patients recover and have a normalized cardiac function within a few weeks.[1][2][3]
Complications
Complications of stress cardiomyopathy include:[1][4][5][3][6][7][8][9][10][11]
- Heart failure
- Pulmonary edema
- Cardiogenic shock
- Bradycardia
- Arrythmias, mainly QT prolongation and ventricular arrhythmias
- Left ventricular mural thrombus
- Mitral valve dysfunction
- pulmonary embolism
- Mitral regurgitation
- LV free wall rupture
- Heart rupture
- Death
Prognosis
The prognosis of stress cardiomyopathy is generally good, even without medical therapy.[5][3] Most patients have a restored cardiac function within a few weeks.[2][3] However, fatal complications such as LV free wall rupture and heart rupture may occur and mortality rate in patients with stress cardiomyopathy ranges from 0-8%.[1][5]
