Marathon Runners

Objectives Running a marathon has been equivocally associated with acute changes in cardiac performance. First-phase ejection fraction is a novel integrated echocardiographic measure of left ventricular contractility and systo-diastolic coupling which has never been studied in the context of physical activity. The aim of this study was to assess first-phase ejection fraction following recreational marathon running along with standard echocardiographic indices of systolic and diastolic function. Design and participants: Runners (n = 25, 17 males), age (mean ± standard deviation) 39 ± 9 years, were assessed before and immediately after a marathon race which was completed in 4 h, 10 min ± 47 min. Main outcome measures Central hemodynamics were estimated with applanation tonometry; cardiac performance was assessed using standard M-mode two-dimensional Doppler, tissue-doppler imaging and speckle-tracking echocardiography. First-phase ejection fraction was calculated as the percentage change in left ventricular volume from end-diastole to the time of peak aortic blood flow. Results Conventional indices of systolic function and cardiac performance were similar pre- and post-race while aortic systolic blood pressure decreased by 9 ± 8 mmHg ( P < 0.001) and first-phase ejection fraction increased by approximately 48% from 16.3 ± 3.9% to 22.9 ± 2.5% ( P < 0.001). The ratio of left ventricular transmitral Doppler early velocity (E) to tissue-doppler imaging early annular velocity (e′) increased from 5.1 ± 1.8 to 6.2 ± 1.3 ( P < 0.01). Conclusion In recreational marathon runners, there is a marked increase in first-phase ejection fraction after the race despite no other significant change in cardiac performance or conventional measure of systolic function. More detailed physiological studies are required to elucidate the mechanism of this increase.

Myocardial Blush Grade

Background: The myocardial blush grade (MBG) during primary-PCI predicts long-term recovery of left ventricular function. Tissue Doppler imaging (TDI) quantitatively assess regional myocardial function by measuring systolic strain (SS). No data are available on the correlation between MBG and the infarcted segmental systolic function by TDI in STEMIpts. Methods: We evaluated 40 STEMI pts, divided in four groups (MBG 0; MBG 1; MBG 2; MBG 3) 10 pts for each goup. Primary PCI was performed according to current standard guidelines. Coronary angiograms were analyzed off-line by two expert interventional cardiologists in a blinded manner. MBG were estimated visually. Sixteen-segments model was applied and regional myocardial function was evaluated, immediately after primary PCI, by measuring SS by TDI . Only SS value in infarcted segments was correlated with the MBG. Results: No significative difference was observed between groups except for family history of CAD that was higher in MBG 2 group. Mean ejection fraction (39,1 ± 8,8%) and mean symptoms to balloon time(4.3 ± 1.6 h ) was similar in the population. 136 infarcted segments were studied by TDI. A significant direct correlation between the MBG and the SS (r=0.79; p<0.005) (Fig.1 ). We also observed a significative difference (p<0.005) between mean SS in pts with MBG ≤0 –1 (7.6 ± 2.4%) and in pts with MBG≥2–3(22.6 ± 5.2). Conclusions: Abnormal values of SS was observed in infarcted segments. The significant correlation observed between the MBG and SS may demonstrate that MBG represent an important predictive index not only of good reperfusion but also of rapid segmental function recovery; similarly an evaluation of SS after primary PCI could be useful to evaluate if primary percutaneus reperfusion has been effective or not.

Background Thalassemia is a major public health problem inIndonesia. Cardiac diseases remain as the main cause of death inthese patients due to iron overload. Although the T2* magneticresonance imaging has been considered as the gold standard forassessing cardiac iron overload but it has limited availability.The tissue doppler imaging (TDI) echocardiography, a fairly newand easy method that is suggested, can detect early abnormalmyocardial iron overload.Objective To assess myocardial systolic and diastolic functionof thalassemic patients using TDI and examine their correlationwith serum ferritin level.Methods A cross􀁌sectional study was conducted from January toMarch 2011 at the Harapan Kita Women and Children Hospital.We performed clinical examination, serum ferritin level, as wellas conventional and tissue doppler echocardiography on allsubjects.Results We included 34 regularly􀁌tranfused patients, of which17 were boys. The mean age of the subjects was 11.6 (SD 4.7years, range 2.6 􀁌 20 years). Mean pulse rate and blood pressurewere within normal range. Hemoglobin level at inclusion rangedfrom 5.8 to 6 g/dL. Almost all patients did not receive regularchelation therapy. Median serum ferritin level was 6275 ng/mL(range 2151 - 17,646 ng/mL). Conventional echocardiographyshowed normal systolic function, but some diastolic dysfunctionswere found including E wave abnormalites in 4 patients, A waveabnormalites in 3, and E/A ratio abnormalites found in 3. TheTDI showed decreased systolic function (Sa wave abnormality) in9 patients and diastolic dysfunctions (Ea wave abnormality in 11patients and Aa wave abnormaly in 2). No abnormality was foundin Ea/Aa and ElEa ratios. There was a weak negative correlationbetween ferritin level and Sa wave and Ea wave respectively anda moderately negative correlation between ferritin level and Ea/Aa ratio. There was no correlation between serum ferritin andAa wave or ElEa ratio.Conclusion TDI identifies a greater number of patients Mthsystolic and diastolic myocardial dysfunction than was revealedby conventional echocardiography. There was a weak negativecorrelation between serum ferritin to Sa wave and Ea wave, and amoderately negative correlation between ferritin and Ea/Aa ratio.There was no correlation between serum ferritin and Aa wave orElEa ratio.

AbstractBackgroundNewer echocardiographic techniques may allow for more accurate assessment of right ventricular function. Adult studies have correlated these echocardiographic measurements with invasive data, but minimal data exist in the paediatric congenital heart population. The purpose of this study was to evaluate echocardiographic measurements that correlate best with right ventricular systolic and diastolic catheterisation parameters.MethodsPatients with two-ventricle physiology who underwent simultaneous echocardiogram and cardiac catheterisation were included in this study. Right ventricular systolic echocardiographic data included fractional area change, displacement, tissue Doppler imaging s’ wave, global longitudinal strain, and strain rate s’ wave. Diastolic echocardiographic data included tricuspid E and A waves, tissue Doppler imaging e’ and a’ waves, and strain rate e’ and a’ waves. E/tissue Doppler imaging e’, tissue Doppler imaging e’/tissue Doppler imaging a’, E/strain rate e’, and strain rate e’/strain rate a’ ratios were also calculated. Catheterisation dP/dt was used as a marker for systolic function and right ventricular end-diastolic pressure for diastolic function.ResultsA total of 32 patients were included in this study. The median age at catheterisation was 3.1 years (0.3–17.6 years). The DP/dt was 493±327 mmHg/second, and the right ventricular end-diastolic pressure was 7.7±2.4 mmHg. There were no significant correlations between catheterisation dP/dt and systolic echocardiographic parameters. Right ventricular end-diastolic pressure correlated significantly with strain rate e’ (r=−0.4, p=0.02), strain rate a’ (r=−0.5, p=0.03), and E/tissue Doppler imaging e’ (r=0.4, p=0.04).ConclusionCatheterisation dP/dt did not correlate with echocardiographic measurements of right ventricular systolic function. Strain rate and tissue Doppler imaging analysis significantly correlated with right ventricular end-diastolic pressure. These values should be further studied to determine whether they may be used as an alternative method to estimate right ventricular end-diastolic pressure in this patient population.
