CHF: Congestive heart failure. VT/VF: Ventricular tachycardia/ventricular fibrillation. Renal f.: Acute renal failure. The incidence of medical complications was higher during the crisis, in the absence of a higher risk profile at baseline, suggesting an influence by poorer quality of care alone or combined with other factors such as impaired social support or depression. Asterisks denote a p value of less than 0.05.
