Nowadays Platelet counts (PC) and volumetric platelet indices are available routinely in most laboratories and reflect the level of mobility and production of platelets. It seems that the excessive flexibility and size of the platelets and their local activation have correlation with extent of ischemic heart disease. So our objective is the study of platelet indices in ischemic heart disease. This non-randomized prospective study was performed on 245 patients with ischemic heart disease, who underwent the coronary angiography. The patients were divided into four groups: stable angina, unstable angina, acute myocardial infarction and control group;and then platelet indices, including the platelet counts (PC), the average platelet volume (MPV), the Platelet Distribution Width (PDW) and plateletcrit (PCT) in each group with the extent of coronary disease were compared based on an Syntax Score system and observational methods. The average ages of the patients were 57 years and 65% of them were male and the rest were female. A significant difference is exists between indices in all three groups compared to the control that this difference was related to gender and the type of the coronary artery involvement. However, only in infarction group, PDW in different disease intensities was significantly different. In this study, unlike many of the previous studies no relationship was found between the MPV with the extent of coronary disease.展开更多

Methods and Materials: There were 88 (36 men and 52 women) end stage renal disease (ESRD) patients recruited for the study. They received regular haemodialysis three times per week at the haemodialysis units of a university medical centre (Golestan hospital) during year 2011. We compared the arrhythmogenic effects of two dialysis techniques. Results: There was a tendency in the HD solution with constant (3 mEq/l) K for premature ventricular complex (PVC) appearance in to be reduced as compared with constant (2 mEq/l) K in the time of dialysis period, although this reduction was not statistically significant(P = 0.09). There was a significant reduction in SVC in the HD solution with constant (3 mEq/l) K as compared with constant (2 mEq/l) K. Discussion: In conclusion, the use of a model of intra-HD potassium that is more close to potassium serum concentration of ESRD patients can reduce the arrhythmogenic effect of HD in patients on regular HD treatment.展开更多

Because of nonspecific symptoms, early diagnosis may be a challenge [1] [2]. Left atrial myxoma may or may not produce characteristic findings on auscultation. Two-dimensional echocardiography is the diagnostic procedure of choice. Most atrial myxomas are benign and can be removed by surgical resection. Cardiac myxoma is located mostly in left atrium [3]. This was amazing huge mass of cardiac myxoma in unusual part of the heart with the patient showed significant response to anticoagulation after presumed recurrence of tumor. Case Presentation: A case of giant right atrial myxoma mimicking the right ventricular tumor is described. Surgery was performed in 41 years old female and the fist like tumor with its stalk was excised. Surprisingly it recurred after 2 month as the smaller tumor was completely resolved with anticoagulation therapy. In addition because of previous normal echocardiography that was done for another reasons, we estimated the speed of tumor’s growth (3 millimeter/month). Conclusion: To sum up a very large myxoma in right ventricle may only present with occasional dyspnea and we can diagnose it with precise evaluation and with performing on time echocardiography.展开更多
