Effects of carvedilol therapy on restrictive diastolic filling pattern in chronic heart failure.

abstract：BACKGROUND:Few data are available on the temporal patterns of health resource utilization (HRU) and expenditures around paroxysmal supraventricular tachycardia (PSVT) diagnosis. This study assessed the longitudinal trends in HRU and expenditures in the 3 years preceding and subsequent to PSVT diagnosis. METHODS:Adult ...
