Overall, conventional echocardiography can detect some differences between young athletes with eccentric and concentric type of athlete's heart but it is incapable of revealing differences in intrinsic myocardial functions. However, analysis using STE demonstrated increased systolic functions in athletes commensurate with increased load, with unaltered diastolic functions.

Carbon monoxide (CO) poisoning is the leading cause of death from intoxication. In CO poisoning, it is important to know if there are any symptoms regarding myocardial damage, which are usually unobserved as a result of hypoxia. This study was planned to assess myocardial damage in young healthy patients with CO poisoning. Eighty-three young healthy cases who had been exposed to CO were included in this study. The demographic and clinical characteristics, the origin of CO gas and smoking habits of the patients were recorded. The evaluation of ECG, peripheral ABG, complete blood count and serial cardiac biomarkers (creatine kinase, creatine kinasemyocardial band and troponin I) measurements were performed in all cases. Additionally, echocardiogram (ECHO) and myocardial perfusion single-photon emission computed tomography (SPECT) were performed at the appropriate times in all cases. The mean age of the patients was 27.39 /10.9 years. The main complaint of the patients was loss of consciousness with a 62.7% rate. The average carboxyhaemoglobin level of the patients was 34.49 /15.9%. Sinus tachycardia was present in 26.5% of patients. Diagnostic ischaemic ECG changes were present in 14.4% of patients. In myocardial SPECT, myocardial ischaemic damage was observed in 9 cases, in 6 of whom ECHO findings were also confirmed. Myocar-dial damage due to CO poisoning should not be ignored. If patients are at risk in terms of myocardial damage, further studies, such as ECHO and scintigraphy are needed to determine myocardial damage resulting from CO poisoning. However, in the young adults of the risk group, if the baseline ECG and serial cardiac biomarkers are normal, further studies such as ECHO and scintigraphy, considering the length of exposure and the severity of poisoning, may not be necessary for the evaluation of myocardial damage due to CO poisoning.

Atrial appendage aneurysms are extremely rare entities in cardiology practice. There are reports of solitary left and right atrial appendage aneurysms in the literature. A case of biatrial appendages aneurysms is reported here. This is the first report of such an anomaly.

This study demonstrates that right ventricular strain and strain rate were lower in patients with left ventricular inferior wall myocardial infarction with, compared to without, right ventricular infarction.

After regular and prolonged training, some physical and structural changes occur in the heart. Strain (S) imaging and Strain Rate (SR) imaging are new and effective techniques derived from tissue Doppler imaging (TDI) which examine systolic and diastolic functions. The aim of the present study was to evaluate left ventricular TDI and S/SR imaging properties in athletes and sedentary controls. The study population consisted of 26 highly trained athletes (group I) and age, sex and body mass index (BMI) adjusted 23 control subjects (group II) who had no pathological conditions. Using standard transthoracic and Doppler echocardiographical measurements and reconstructed spectral pulsed wave tissue Doppler velocities, the S/SR imaging of six different myocardial regions were evaluated. There was a significant increase in left ventricular systolic (LVSD) and diastolic (LVDD) diameter, inter-ventricular septum (IVS), left ventricular mass (LVm), left atrial diameter (LA), and transmitral Doppler peak E velocity (flow velocity in early diastole) between group I and group II in the case of echocardiographic findings. In athletes, TDI analysis showed a significantly increased mitral annulus lateral TDI peak early diastolic (E) velocity (18.8 ± 4.1 cm/s vs. 15 ± 3.5 cm/s, P < 0.01), septal TDI peak E velocity (15.8 ± 2.8 cm/s vs. 12.8 ± 2.4 P < 0.001). There were no significant differences in myocardial velocity imaging parameters between group I and group II. Peak systolic strain/strain rates of septal and lateral walls in group I were significantly higher than group II. This study demonstrates that left ventricular S/SR imaging was higher in athletes than in healthy subjects. In addition to traditional echocardiographic parameters, SI/SRI could be utilised as a useful echocardiographic method for cardiac functions of athletes.

Background and ObjectivesThe aim of this study was to investigate the impact of treatment with oral trimetazidine (TMZ) applied before and after percutaneous coronary interventions (PCI) on short-term left ventricular functions and plasma brain natriuretic peptide (BNP) levels in patients with non-ST segment elevation myocardial infarction (NSTEMI) undergoing PCI.Subjects and MethodsThe study included 45 patients who were undergoing PCI with the diagnosis of NSTEMI. The patients were randomized into two groups. The first group (n=22) of the patients hospitalized with the diagnosis of NSTEMI was given conventional therapy plus 60 mg TMZ just prior to PCI. Treatment with TMZ was continued for one month after the procedure. TMZ treatment was not given to the second group (n=23). Echocardiography images were recorded and plasma BNP levels were measured just prior to the PCI and on the 1st and 30th days after PCI.ResultsThe myocardial performance index (MPI) was greater in the second group (p=0.02). In the comparison of BNP levels, they significantly decreased in both of the groups during the 30-day follow-up period (29.0±8 and 50.6±33, p<0.01 respectively). However, decreasing of BNP levels was higher in the group administered with TMZ. The decrease of left ventriclular end-diastolic volume was observed in all groups at 30 days after intervention, but was higher in the group administered with TMZ (p=0.01).ConclusionTrimetazidine treatment commencing prior to PCI and continued after PCI in patients with NSTEMI provides improvements in MPI, left ventricular end diastolic volume and a decrease in BNP levels.

S and Sr imaging can be considered a robust technique for the assessment of the LAA systolic deformation.

MDCT can be used to guide interventionalists for CRT by providing anatomical details of the cardiac venous system rapidly and noninvasively.
