Left Ventricular Function Impaired in Asymptomatic Elderly Patients with Type 2 Diabetes
In a recent study published in Angiology, researchers in Greece investigated left ventricular function in 24 elderly patients with type 2 diabetes, who were asymptomatic and had no history of hypertension, coronary or valvular heart disease. The study found that left ventricular systolic and diastolic indices were impaired in these patients, indicating a distinct entity of diabetic cardiomyopathy.
Key Takeaways:
- The study found that left ventricular systolic indices, including ejection fraction and fractional shortening, were reduced in asymptomatic elderly patients with type 2 diabetes compared to controls.
- Diastolic indices, including the E wave, A wave, E/A ratio, isovolumic relaxation time, and deceleration time, were also impaired in these patients.
- The myocardial performance index (MPI) was significantly increased in patients with type 2 diabetes, indicating impaired left ventricular function.
- The study suggests that left ventricular dysfunction is a distinct entity in diabetic patients with congestive heart failure, even in the absence of significant coronary artery stenosis.
- The study's findings highlight the importance of early detection and management of diabetic cardiomyopathy.
Statistics:
- Ejection fraction (EF) was reduced in patients with type 2 diabetes (0.60[+ or -]0.10 m/sec) compared to controls (0.72[+ or -]0.08 m/sec).
- The E wave was reduced in patients with type 2 diabetes (0.60[+ or -]0.10 m/sec) compared to controls (0.72[+ or -]0.08 m/sec).
- The myocardial performance index (MPI) was significantly increased in patients with type 2 diabetes (0.640[+ or -]0.170) compared to controls (0.368[+ or -]0.098).
