ABSTRACT
BACKGROUND:
The cardiac time intervals include the isovolumic contraction time (IVCT), the left ventricular ejection time (LVET), the isovolumic relaxation time (IVRT) and the combination of all the cardiac time intervals in the myocardial performance index (MPI) (defined as [(IVCT+IVRT)/LVET)]. Whether the cardiac time intervals change over time and which clinical factors that accelerate these changes is not well-established. Additionally, whether these changes are associated with subsequent heart failure (HF), remains unknown.METHODS:
We investigated participants from the general population (n = 1064) who had an echocardiographic examination including color tissue Doppler imaging performed in both the 4th and 5th Copenhagen City Heart Study. The examinations were performed 10.5 years apart.RESULTS:
The IVCT, LVET, IVRT and MPI increased significantly over time. None of the investigated clinical factors were associated with increase in IVCT. Systolic blood pressure (standardized ß= - 0.09) and male sex (standardized ß= - 0.08) were associated with an accelerated decrease in LVET. Age (standardized ß=0.26), male sex (standardized ß=0.06), diastolic blood pressure (standardized ß=0.08), and smoking (standardized ß=0.08) were associated with an increase in IVRT, while HbA1c (standardized ß= - 0.06) was associated with a decrease in IVRT. Increasing IVRT over a decade was associated with an increased risk of subsequent HF in participants aged <65 years (per 10 ms increase HR 1.33; 95%CI (1.02-1.72), p = 0.034).CONCLUSION:
The cardiac time increased significantly over time. Several clinical factors accelerated these changes. An increase in IVRT was associated with an increased risk of subsequent HF in participants aged <65 years.Palabras clave
