There was no evidence of any previous heart attacks and he had a normal echocardiogram, according to the report.
We are not aware of any previous heart sound model rigorously evaluated as our proposal.
Because deaths from other forms of heart disease were often a consequence of previous ischaemic heart disease in our study population, and patterns of the hazard ratios were similar for ischaemic heart disease and other forms of heart disease, we estimated the hazard ratios for the combined category and for ischaemic heart disease separately.
*Because deaths from other forms of heart disease were often consequence of previous ischaemic heart disease in our study population and patterns of hazard ratios were similar for ischaemic heart disease and other forms of heart disease, we present hazard ratios for combined category and also for ischaemic heart disease separately.
Because of his cardiomyopathy, the patient had undergone previous heart operations that left him dependent on a pacemaker and later a dual-purpose implant to continuously stimulate his heart.
The F.D.A. has traditionally been cautious about diet pills because of previous safety issues, such as the heart valve damage caused by a component of the fen-phen combination.
Aggravation of previous chronic heart disease and chronic renal failure are the most common clinical pictures.
Cases were further identified as having a history of diabetes (n = 2), heart problems (e.g., previous heart attack, irregular heartbeat, angina, heart failure; n = 1), previous blood clot, transfusion or bleeding tendency (n = 1), or cancer (n = 2).
Previous heart disease was defined as a diagnosis of coronary heart disease and/or heart failure prior to dialysis initiation.
Because the proportional hazards assumption was violated by the variables "systolic blood pressure" and "previous heart failure," we included an interaction term between "systolic blood pressure" and the logarithm of survival time, and used "previous heart failure" as a stratification variable in the model.
