- Abstract
<bold>Purpose: </bold>To quantitatively investigate left ventricular volume and function in middle-aged healthy subjects.<bold>Materials and Methods: </bold>Ninety healthy volunteers underwent cardiac 3 Tesla MRI. The left ventricular end-diastolic volume (EDV) and end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), cardiac output (CO), myocardial mass (MM), and their normalized indices (EDVI, ESVI, SVI, CI, and MI, respectively) after corrected with the body surface area (BSA) were analyzed and compared at different ages.<bold>Results: </bold>All subjects had successfully completed the 3-Tesla cardiac MR. Females had significantly smaller EDV (110.5 ± 9.2 versus 125.7 ± 8.3 mL), ESV (36.1 ± 3.5 versus 41.5 ± 3.8 mL), SV (74.3 ± 6.3 versus 84.2 ± 6.7 mL), CO (5.4 ± 0.8 versus 5.8 ± 0.9 l/min) and MM (73.0 ± 10.5 versus 94.8 ± 10.6 g) than males (P < 0.05). The EF had no significant (P = 0.47) difference between genders (67.3 ± 1.7 percent in females versus 66.9 ± 2.4 percent in males). After normalization with BSA, no significant (P > 0.05) difference was detected between the genders in EDVI (71.2 ± 4.3 versus 71.1 ± 4.2 mL/m2 , P = 0.882), ESVI (23.3 ± 1.9 versus 23.5 ± 1.9 mL/m2 , P = 0.733) and SVI (47.9 ± 2.9 versus 47.7 ± 3.7 mL/m2 , P = 0.698) except for CI and MI. Females had significantly (P < 0.05) greater CI (3.5 ± 0.4 versus 3.3 ± 0.4) but smaller MI (46.9 ± 5.3 versus 53.6 ± 7.6) than males. EDV, EDVI, ESV, ESVI, SV, and SVI significantly (P < 0.05) decreased with age increase. BSA was positively correlated with EDV, ESV, SV, MM, and CO. No significance (P > 0.05) was detected in other parameters.<bold>Conclusion: </bold>The left ventricular volume and function differs in women compared with men in the middle-aged population, and these parameters have a tendency of decrease with ageing.
