Methods: A descriptive study was performed in 19 elite male powerlifters, who exercised for 12 weeks, four days per week with an intensity of 60 – 90% assessed from 1 repetition maximum and 90 – 120 min per session. Carotid-femoral pulse wave velocity (cfPWV), augmentation index and central blood pressure were measured by applanation tonometry using the SphygmoCor device, and an echocardiographic examination was performed at baseline and after 12-week SSTP. Results: Subjects ’ mean brachial and central systolic blood pressure decreased signi fi cantly after the training period (132.3±8.8 vs 124.3±8.7 mmHg, p =0.002 and 110.1±7.7 vs 104.5 ±8.7 mmHg, p =0.008, respectively). Strength training signi fi cantly improved systolic tricuspid annular velocity and mitral E/e ’ ratio ( p <0.05). There were no signi fi cant differences in cfPWV and augmentation index at baseline and after SSTP. Conclusion: The 12-week supervised strength pre-seasonal training program signi fi cantly decreased brachial and central systolic blood pressure in male elite powerlifting athletes. The strength training program decreased left ventricular fi lling pressure and improved right ventricular systolic function. No signi fi cant effect of strength training on aortic stiffness was found.","PeriodicalId":42306,"journal":{"name":"Research Reports in Clinical Cardiology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/RRCC.S198590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43922858","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}

Mujuni","doi":"10.2147/RRCC.S159472","DOIUrl":"https://doi.org/10.2147/RRCC.S159472","url":null,"abstract":"Purpose: Chronic kidney disease (CKD) is prevalent in sub-Saharan Africa and is a significant cause of mortality, which may result from kidney failure or congestive heart failure – a frequent complication of CKD. There is however scarcity of documented literature on the magnitude and associated factors of echocardiographically determined left ventricular (LV) dysfunction among CKD patients in Tanzania. Patients and methods: A prospective cross-sectional study was conducted from May 2014 to January 2015 at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania. Patients ≥ 18 years with CKD were consecutively enrolled. Clinical characteristics, cardiovascular risk profiles, and laboratory findings including serum creatinine, urea, hemoglobin, and cholesterol levels were collected. Echocardiography was performed to assess LV function using standard criteria. Results: One hundred and ninety-one CKD patients fulfilled the inclusion criteria. The mean ± SD age was 48 ± 13 years, and 54.5% were men. A total of 98.4% of the patients were hypertensive, and diabetes was present in 22.8% while 97.9% had end-stage renal disease. The prevalence of LV systolic and diastolic dysfunction was 16.2% and 68.6%, respectively. A clinical finding of heart failure was the only independent predictor of LV systolic dysfunction (odds ratio [OR] = 2.9, p = 0.012), while independent predictors of LV diastolic dysfunction were anemia (OR = 4.9, p = 0.01), severe hypertension (OR = 9.2, p = 0.001), and female gender (OR = 1.7, p = 0.002). Conclusion: LV dysfunction is prevalent among CKD patients seen at MNH and is associated with clinical heart failure, anemia, severe hypertension, and female gender. Echocardiography should be performed in patients with CKD to detect overt or subclinical LV dysfunction.","PeriodicalId":42306,"journal":{"name":"Research Reports in Clinical Cardiology","volume":"9 1","pages":"11-21"},"PeriodicalIF":0.4,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/RRCC.S159472","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43422334","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}

Bâ","doi":"10.2147/RRCC.S141572","DOIUrl":"https://doi.org/10.2147/RRCC.S141572","url":null,"abstract":"Background: The study of the right ventricle (RV) is of particular interest as it is believed to be involved in several heart diseases. Peripartum cardiomyopathy (PPCM) is characterized by left ventricular systolic dysfunction occurring between the last month of pregnancy and the fifth month postpartum. It is often combined with RV dysfunction, but this has rarely been described in the literature. The main aim of this study was to assess the prevalence of RV dysfunction in a PPCM population. Methods: We conducted a prospective and investigative study at the Cardiac Clinic of the Aristide Le Dantec Teaching Hospital in Dakar, Senegal, between March and June 2013. All patients hospitalized during the study period and meeting the diagnostic criteria for PPCM were included. Results: During the study period, 326 patients were hospitalized in the cardiology department; 19 were diagnosed with PPCM corresponding to a hospital prevalence of 5.8%. All patients had left ventricular dysfunction, with an average ejection fraction of 23.01% ± 9.73% at the Simpson biplane. Based on the tricuspid annular plane systolic excursion (TAPSE), 11 out of the 19 patients (57.9%) had RV systolic dysfunction. Ten patients (52.6%) had an Sa tricuspid wave (speed of the systolic wave to the tricuspid ring in tissue Doppler) below the standard. The average RV area shortening was 23.73% ± 14.16%, with extremes of 7.8% and 53.7%. Fifteen patients (78.9%) had a rate of shortening fraction of the surface area of RV below the standard. When the other parameters were taken into account, 15 patients (78.9%) had at least 3 of the following indexes altered: fractional area change (FAC), Sa tricuspid, TAPSE, and the ratio between the sum of both isovolumic times and the ejection time (TEI index). Conclusion: RV dysfunction is common in PPCM. In view of the prognostic interest on the right ventricle; its evaluation must take into account all of the measurement parameters in order to allow for better detection.","PeriodicalId":42306,"journal":{"name":"Research Reports in Clinical Cardiology","volume":"8 1","pages":"61-66"},"PeriodicalIF":0.4,"publicationDate":"2017-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/RRCC.S141572","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44252748","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}
