Myocardial structure as a determinant of pre- and postoperative ventricular function and long-term prognosis after valve replacement for aortic stenosis.
Long-term results after aortic value replacement for aortic stenosis can be correlated to a cardiac-related pre-operative risk profile. This predictability indicates that there is a common basis in subtle or overt structural abnormalities of left ventricular myocardium. ⋯ Abnormalities of the hypertrophied left ventricular muscle cell and the degree of muscle hypertrophy are, to some degree, underlying determinants of pre-operative symptomatology, pre- and postoperative ventricular function, and early and late mortality after valve replacement for aortic stenosis. Incomplete hypertrophy impaired results, was related to pre-operative myocardial structural abnormalities.

QT interval dispersion as a predictor of arrhythmic events in congestive heart failure. Importance of aetiology.
Identification of patients with congestive heart failure at risk of sudden death remains problematic and few data are available on the prognostic implications of QT dispersion. We sought to assess the predictive value of QT dispersion for arrhythmic events in heart failure secondary to dilated cardiomyopathy or ischaemic heart disease. ⋯ In congestive heart failure, abnormal QT dispersion can identify patients with dilated cardiomyopathy who are at high risk of arrhythmic events.

Influence of concomitant disease on patterns of hospitalization in patients with heart failure discharged from Scottish hospitals in 1995.
To determine the prevalence of common, serious, concomitant conditions complicating admissions with heart failure and how such conditions influence the length of hospital stay. ⋯ A large proportion of deaths and discharges for heart failure are associated with conditions other than heart failure that may precipitate, contribute to or complicate admission. Treatment for heart failure that does not also seek to reduce the risk associated with common concomitant diseases may miss opportunities to reduce the overall risk of hospitalization.
