Secondary prevention of coronary heart disease in elderly population of Turkey: A subgroup analysis of ELDERTURK study.

BACKGROUND: Secondary prevention plays an important role after acute coronary event due to high risk of adverse events in elderly. In present study we aimed to evaluate the lifestyle, management of risk factors and medical treatment for secondary protection in elderly patients with known coronary heart disease (CHD). METHODS: ELDERTURK is a non-interventional, multi-centered, observational study, which included total of 5694 elderly patients ( > 65 years) from 50 centers in Turkey. In this study elderly patients from the ELDERTURK population with known CHD were evaluated for cardiovascular risk factors, comor- bidities and medication usage. RESULTS: A total of 2976 (52.3% of study) out of 5694 patients included in the ELDERTURK study were evaluated. All had known CHD with a mean age of 73.4 ± 6.2 years and 60.3% were male. 13.0% of patients were smokers, 42.4% were overweight and 21.1% were obese. Only 23.6% of patients reported to do regular exercise, 73.4% had history of hypertension, 47.4% had dyslipidemia and 33.9% had diabetes mellitus. The rate of patients with systolic blood pressure > 140 mmHg were 31.1% and only 13.9% of patients had a recommended ≤ 70 mg/dL level of low-density lipoprotein cholesterol. Anti- platelet, statin, beta-blocker and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker usage was limited to 27.3%. CONCLUSIONS: The ELDERTURK study shows that many patients with CHD have a high prevalence of modifiable risk factors and unhealthy lifestyle. Apart from this, many patients are not receiving thera- peutic intervention and as a consequence most were not achieving the recommended goals.

Giant J (Osborn) Wave due to Bonsai Abuse: Comments on Clinical Practice.

BACKGROUND: Osborn wave, typically associated with hypothermia, is currently referred to as one of the J wave syndromes due to its clinical potential to develop lethal cardiac arrhythmia; it may rarely be observed in a non-hypothermic setting such as cannabis abuse. CASE REPORT: In this paper, we presented two young cases who presented to the emergency services with unconsciousness, drowsiness, and hypoxia, and also J wave on electrocardiography (ECG) due to Bonsai abuse. CONCLUSION: Osborn wave may be a significant criterion to initiate close monitoring in a coronary care unit, with supportive treatment and mechanical ventilation as necessary in those patients who abuse Bonsai.

P-wave dispersion doesn't increase in patients with epilepsy.

AIM: Epileptic seizures have occasionally been associated with cardiac conditions as atrioventricular blocks, long QT syndrome etc. P-wave dispersion (PWD), which is the difference between the longest (P max) and shortest P-wave duration (P min), is considered as a forerunner of atrial fibrillation. In this study, we investigated P-wave dispersion (PWD) in epileptic patients; based on the hypothesis that microthromboembolism may occur in atrial fibrillation. METHODS: Seventy five patients with mixed types of epilepsy and 50 age and sex matched healthy individuals were included into the study. P max, P min and PWD values were calculated for each subject from an ECG. RESULTS: The mean age of subjects in the epilepsy group and control group were similar (p>0.05). P max in patients with epilepsy was 125.1±0.7 ms, P min was 67.3±10.3 ms, and PWD was 57.6±8.3 ms while these values in the control group were 116.8±11.0 ms, 66.5±5.5 ms and 46.8±7.1 ms, respectively. There were no statistically significant difference between two groups (p>0.05). CONCLUSIONS: PWD does not increase in patients with mixed types of epilepsy. Therefore we believe that microthromboembolism due to atrial fibrillation can't cause epileptic seizures in patients with no structural heart disease.

Cardiovascular risk scores for coronary atherosclerosis.

OBJECTIVE: The objective of this study was to compare frequently used cardiovascular risk scores in predicting the presence of coronary artery disease (CAD) and 3-vessel disease. METHODS AND RESULTS: In 350 consecutive patients (218 men and 132 women) who underwent coronary angiography, the cardiovascular risk level was determined using the Framingham Risk Score (FRS), the Modified Framingham Risk Score (MFRS), the Prospective Cardiovascular Münster (PROCAM) score, and the Systematic Coronary Risk Evaluation (SCORE). The area under the curve for receiver operating characteristic curves showed that FRS had more predictive value than the other scores for CAD (area under curve, 0.76, P < or = 0.001), but all scores had good specificity and positive predictive value. For 3-vessel disease, the FRS had better predictive value than the other scores (area under curve, 0.74, P < or = 0.001), but all scores had good specificity and negative predictive value. CONCLUSION: The risk scores (FRS, MFRS, PROCAM, and SCORE) may predict the presence and severity of coronary atherosclerosis.The FRS had better predictive value than the other scores.

Classic mitral valve prolapse causes enlargement in left ventricle even in the absence of significant mitral regurgitation.

AIM: The aim of this study was to evaluate whether left ventricular size was increased in patients with classic bileaflet mitral valve prolapse (MVP) in the absence of significant mitral regurgitation (MR). METHOD: Patients with classic bileaflet MVP were included as the case group. Two different control groups were established. The first control group was composed of the patients with mild MR caused by the reasons except MVP. The second control group consisted of healthy individuals whose echocardiograms were normal. The patients with moderate or severe MR and having abnormality in the other valves were excluded. RESULTS: There were 20 patients in each group. Systolic and diastolic diameters and volumes of left ventricle (LV) in the MVP group were significantly higher than those in the control groups. In 10 of the patients in the MVP group, LV internal diastolic diameter (LVIDD) values were measured as ≥5.7 cm, whereas increased LVIDD value was detected in only one patient in the other two control groups. There was a significant difference in terms of the presence of increased LVIDD values between the MVP group and the control groups. Despite this enlargement in the LV dimension, the LV ejection fractions were found similar in all groups. Furthermore, it was found that the lengths of both anterior and posterior mitral leaflets in MVP group were significantly higher than those in the control groups. CONCLUSION: The LV diameters and volumes of patients with classic bileaflet MVP were found to be increased even in the absence of significant MR. These results need to be supported by large-scale clinical studies.

Alternative method for accessing the target coronary artery in patients with difficult coronary anatomy: exchanging the diagnostic catheter with a guiding catheter.

We report a method of the placement of the guiding catheter in two cases in which the diagnostic catheter could be easily engaged to the target coronary arteries but not a guiding catheter, due to a distorted aortic sinus and an osteal subtotal occlusion, respectively. After engaging to the target coronary artery with a diagnostic catheter, a coronary guidewire was advanced through the diagnostic catheter, and exchanged with a guiding catheter over the guidewires. The procedures were completed with success.

Intravascular ultrasound (IVUS) is widely used to assess the severity of coronary artery lesions. Fracture of the IVUS catheter in the coronary artery is very rare and embolization of a fractured segment into other organs has not been reported. A 41-year-old male patient underwent IVUS imaging for further assessment of a lesion detected angiographically in the left main coronary artery. During the procedure, the distal tip of the IVUS catheter fractured in the left main coronary artery. Percutaneous retrieval of the broken fragment was attempted using a coronary snare, but the fragment freed from the snare and embolized into the right renal artery. After placement of a right coronary guide wire catheter in the right renal artery, the fractured tip was captured with a coronary snare and was successfully retrieved.

Effect of position changes on myocardial velocity in healthy subjects evaluated by tissue Doppler echocardiography.

OBJECTIVES: This study designed to assess the effect of different positions of head of the bed on myocardial velocity by tissue Doppler echocardiography in healthy subjects. METHODS: Thirty-nine healthy subjects (32 males/7 females, mean age 24.7 ± 4.9 years) were studied. Tissue Doppler imaging (TDI) was performed and velocities were recorded during systole (Sm) and early (Em) and late (Am) diastole at the tricuspid annulus, septum, and mitral annulus in the four-chamber view. Measurements were performed from different positions of left lateral decubitus (0°, 30°, and 60°). Repeated-measures general linear models were used to assess the change in myocardial velocities. RESULTS: No significant difference between myocardial velocities was found at the mitral anulus and septal TDI recordings in the different angles of left lateral decubitus positions (P > 0.05). However, there were statistically significant difference among tricuspid anulus myocardial tissue velocities in these positions (P < 0.05). CONCLUSIONS: Tricuspid anulus myocardial tissue velocities may be significantly influenced by changing of position in healthy subjects. Effect of position changes should be considered in the assessment of these velocities.
