A variety of applications are covered, with presentation of algorithms and highlighting of tips and tricks. It will be of value for cardiologists, other interested clinicians, those pursuing fellowships in echocardiography, and sonographers; it will also be highly relevant for biomedical engineers, bio-mathematicians, computer scientists, and researchers in medical physics. There would be enormous clinical benefits of any non-invasive technique to estimate the true level of wall abnormal motions. Strain and strain rate are deformation measures. If different components of an object have different velocities, the object shape may be changed. In this article, we mentioned the left ventricular 2- dimensional strain in normal hearts for each different type of strain methods from 5 echocardiography machines and we have also introduced MATLAB software as an echocardiography desk.","PeriodicalId":31436,"journal":{"name":"International Journal of Cardiovascular Practice","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82671916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed at investigating the prevalence of thrombocytopenia and its relationship with the length of stay and mortality among intensive care unit (ICU) patients. Methods: The current prospective cohort study enrolled 150 patients consecutively admitted to the medical ICU during a nine-month period. Patients’ baseline characteristics and underlying diseases were recorded. Laboratory findings and admission mean platelets and platelet counts on the 3rd day of admission were obtained. Patients were divided into thrombocytopenic (platelet count of less than 150×109/L or decrease of platelet to more than 50%) and non-thrombocytopenic groups according to the 3rd day platelet count. Results: Thrombocytopenia was detected in 53(35%) patients while 13 patients (8.6%) had severe thrombocytopenia (platelets count < 50 × 109/L). ICU stay and mortality were significantly higher in patients with thrombocytopenia compared with non-thrombocytopenic patients (16 ± 2.7 vs 12 ± 2.4 days, P = 0.01) and (45.5% vs 37.3%, P = 00.1) respectively. Conclusions: Platelet might be considered as a prognosis monitor in ICU settings. Severe thrombocytopenia could be mentioned as a poor prognostic factor for increased mortality and prolonged hospitalization period in ICU patients.","PeriodicalId":31436,"journal":{"name":"International Journal of Cardiovascular Practice","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82243456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current risk assessment of patients with NSTE-ACS may calculate patients risk for recurrent events but may fail to identify patients with severe coronary artery disease (CAD). The present study aimed to identify predictors of the extent and severity of CAD for prognosis of NSTE-ACS patients undergoing early angiography. Methods: A total of 215 patients with NSTE-ACS were enrolled randomly and followed up between April-2015 and February-2017 at a tertiary healthcare center. The coronary angiography was performed. Patients were divided into two groups: high-risk coronary anatomy (HRCA) and low-risk coronary anatomy (LRCA). Patients were analyzed for baseline, demographic, clinical characteristics, and cardiovascular risk factors, during hospitalization and 30 days post discharge. Results: Among 215 enrolled patients, 90 (mean age: 52.22 ± 10.24 year) and 125 (mean age: 57.78 ± 8.83 year) patients were in the LRCA and HRCA group, respectively.

ASD causes increased volume overload of the right heart. The purpose of this study was to evaluate left ventricular (LV) torsion deformation in ASD patients undergoing transcatheter device closure. Methods: All adult patients who underwent transcatheter device closure with ostium secundum ASD were included in the study. We assessed LV torsion in ostium secundum ASD patient’s pre and post device closure by using speckle tracking echocardiography. Results: A total of 37 patients (22 females and 15 males) were included in this study. The average age was 28 ± 19 years. LV peak basal rotation improved significantly (P = 0.028) in post transcatheter closure. LV torsion (2.88 ± 0.99˚/cm before vs. 3.40 ± 1.41˚/cm after closure, P = 0.009) and twisting (15.12 ± 4.69˚ before vs. 17.95 ± 6.21˚ after closure, P = 0.005) were statistically significant in post transcatheter closure. Volumetric assessment of LV including end-diastolic volume and systolic volume showed significant improvement (P = 0.02, P < 0.01) post device closure. Conclusions: The increased peak LV twisting and torsion was mainly attributed to the improved peak systolic clockwise rotation after ASD device closure. The LV twisting at a younger age was improved after the closure of ASD.","PeriodicalId":31436,"journal":{"name":"International Journal of Cardiovascular Practice","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75259413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were many researches to and fro of CRT-D versus CRT-P implantation in patients with cardiomyopathy (CMP) and left bundle branch block pattern in electrocardiography. In 2012, ACC/AHA/HRS (American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines and the Heart Rhythm Society) guidelines, recommendations for implantable cardioverter defibrillator (ICD), was completely apart to the indications of CRT[1]. In such guidelines, ICD indicated for most of patients with ischemic CMP and patients with non-ischemic CMP with high functional class. Therefore, ICD simultaneously indicated many patients benefitting from CRT. Therefore, the indications for CRT-P are very limited according to these guidelines [1]. The ESC guideline recommends implantation of CRT-P instead of CRT-D only in patients with short life expectancy such as the ones with advanced renal failure [2]. Although left ventricular ejection fraction (LVEF) is an excellent practical marker of ventricular arrhythmic events, however, only a small percentage of ICD recipients receive appropriate ICD therapy [3]. The predictors of appropriate ICD therapy markedly vary between the studies. Non-sustained ventricular tachycardia, abnormal sphericity index, male gender, high NYHA (New York Heart Association) functional class, and smoking were reported as predictors for ventricular arrhythmia in few studies, but still not approved as good markers to change the decision [4-6]. Recently, the benefit of ICD for patients with dilated CMP was doubted in a Danish trial. This trial demonstrated that ICD implantation did not have survival benefits for patients with symptomatic heart failure not caused by coronary artery disease [7]. Accordingly, a recent study showed that midwall fibrosis detected by magnetic resonance imaging (MRI) may be a good predictor for adverse outcomes including ventricular tachyarrhythmia and sudden arrhythmic death in the patients with non-ischemic CMP; hence, CRT-D may be superior to CRT-P in this subgroup of patients with non-ischemic CMP [8]. On the other hand, in many pacemaker-dependent patients, only RV pacing may cause CMP. Kiehl et al., showed that incidence of pacemaker-induced cardiomyopathy was about 12.3% in patients with complete heart block treated with pacemaker; hence, it may be necessary to upgrade their device to CRT [9]. According to the current AHA and ESC guidelines, CRT implantation or upgrading to CRT device is observed in patients with high ventricular pacing and Cardiac Resynchronization Therapy With or Without Defibrillation","PeriodicalId":31436,"journal":{"name":"International Journal of Cardiovascular Practice","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82422891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
