Background: Platelet activation appears to play an important role in thromboembolic complications of infective endocarditis (IE). Mean platelet volume (MPV) is subjects (10.62 ± 1.13 vs. 9.25 ± 0.97 and 8.93 ± 0.82 fL, p < 0.001, respectively). Similarly, the patients with embolic events had increased PDW compared to the non-embolic ones and the control group (16.31 ± 2.42 vs. 14.35 ± 1.97 and 14.04 ± 1.82%, p < 0.001, respectively (Cardiol J 2015; 22, 1: 37-43)

Patients with left ventricular diastolic dysfunction had significantly increased EFT volume.

Objective: Treadmill exercise stress testing for identifying patients with a higher likelihood of coronary artery disease (CAD) before elective coronary angiography is recommended in the current guidelines. In this study, we aimed to evaluate the changes in the hematological parameters before and after exercise stress test in relation with the presence of CAD. Methods:A total of 113 patients with chest pain who underwent treadmill exercise testing and coronary angiography were included in this study. Conclusions: Neutrophil to lymphocyte ratio is an important inflammatory marker that can contribute to treadmill ECG testing in predicting CAD.

Adrenal incidentalomas (AIs) are usually discovered incidentally after imaging unrelated to adrenal glands. We aimed to evaluate standard risk factors for systemic atherosclerosis and echocardiographic changes in patients with nonfunctioning AIs and compare them with normal subjects. We evaluated 70 patients diagnosed with AIs and 51 healthy controls. Mean levels were determined for HbA1c, LDL, uric acid, fasting plasma insulin, HOMA, and neutrophil-to-lymphocyte ratio (NLR), and these values were found to be significantly higher in the patients than the controls. The mean left atrial diameter, interventricular septum thickness, posterior wall thickness, left ventricular mass, E-wave deceleration time, isovolumetric relaxation time, and the median ratio of the early transmittal flow velocity to the early diastolic tissue velocity (E/Em) were higher in patients with AIs compared to controls. The mitral annular early diastolic velocity was lower in patients with AIs. The mean aortic diastolic diameter, stiffness index (SI), and aortic strain were higher, and aortic distensibility was lower in the patients. The mean right ventricular diameter, right atrial major-axis diameter, and right atrial minor-axis diameter were statistically higher in the patient group than the controls. A negative correlation was found between the NLR and aortic strain and aortic distensibility, while a positive correction was found between the NLR and SI. We found altered left ventricular (LV) and right ventricular (RV) echocardiographic findings in patients with AIs without known cardiovascular disease. Aortic stiffness was also increased. These changes may be related to an increase in cardiovascular risk factors in AI patients.

Patients with RMS have increased platelet activity reflected as elevated MPV; and the coexistence of severe mitral regurgitation and presence of left atrial spontaneous echo contrast are determinants of this increment.

Background  Atrial fibrillation (AF) is the most common cardiac arrhythmia and is a major cause of embolic stroke. In patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. Left atrial appendage (LAA) closure is an emerging option in AF patients who are not eligible for oral anticoagulation therapy because of contraindications or high bleeding risk. Case summary  A 67-year-old man with permanent AF and haemophilia was referred for further evaluation of our cardiology clinic by his primary haematologist. The CHA2DS2-VASc score was estimated to be 3 and the HAS-BLED score was 3. Due to high risk of bleeding, we decided to perform percutaneous LAA closure instead of oral anticoagulation. Pre-procedural cardiac computerized tomography angiography and transoesophageal echocardiography were performed for measurements of LAA dimensions and exclude LAA thrombus. Percutaneous LAA occlusion was performed using a 28-mm AmplatzerTM AmuletTM device. The final result was excellent without significant residual leak, pericardial effusion, and embolic complication. Clopidogrel 75 mg/day and aspirin 81 mg/day for 1 month with adequate FVIII prophylaxis and then only aspirin 81 mg/day for 2 months were recommended. No antiplatelet was given after 3 months. The patient did not report any thrombotic or haemorrhagic adverse events and there were no complications related to implanted device after 1 year of follow-up. Discussion  In patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. In this report, we present a case of percutaneous LAA occlusion using AmplatzerTM AmuletTM device in a patient who has haemophilia and permanent AF. LAA closure has the potential to be more cost effective as compared to oral anticoagulation therapy due to lesser necessity of clotting factor infusion.
