In the present study, we have evaluated the impact of registry implementation on PE management. Methods: In the present single-center study, composed of two distinct cohorts, we have evaluated the impact of registry implementation (prospective arm-September 2015 to August 2018) on patient management and survival, and compared it with the same duration when no registry was implied (retrospective arm-September 2012 to August 2015). Results: One hundred and seventy and 182 patients were recruited in the prospective and retrospective arms, respectively. Guideline-recommended risk stratification was significantly overlooked before the introduction of PE registry (100% vs. 45.6% prospective and retrospective arms, respectively [P < 0.001]). A trend toward higher administration of thrombolytic therapy was noted in patients admitted during the registry time (20 [64.5%] vs. 3 [37.5%], P = 0.166). The registry had also significant impact on length of hospital stay (6.72 ± 4.39 days versus 9.35 ± 5.55, P = 0.001, in prospective and retrospective arms, respectively). No significant difference was detected on the 6-month all-cause mortality. However, re-venous thromboembolism was significantly reduced during registry time (2 [1.2%) vs. 22 [12.2%], P < 0.001). Finally, significantly more patients underwent guideline-recommended follow-up during the registry time (107 [72.3%] vs. 30 [16.5%], P < 0.001). Conclusion: Our study showed the implementation of registry had significant effect on PE-related outcome and might have direct impact on burden of pulmonary emboli on the healthcare system.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":"10 1","pages":"40 - 44"},"PeriodicalIF":0.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45359602","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}

Methods: The present retrospective cross-sectional study was conducted on patients who received treatment for CTEPH in Rajaie Cardiovascular Medical and Research Center over the past four years, from 2016 to 2020. The data were obtained from routine hospital admission and outpatient visit records. The patients were divided into PEA, BPA, and medical treatment groups, and the outcomes and complications of the procedures were reported. Results: Twenty-eight patients, at a median age of 40 (33–59) years were included in our study and were followed for approximately 20.0 (16.2–23.7) months. PEA was performed on 13 (46%) patients, BPA on 10 (35%), and medical therapy only on 5 (17%). Death occurred in 4 (30%) patients after surgery, and 10 (77%) had a surgical complication. There were no deaths or recorded complications in the other two groups, but the rates of postprocedural pulmonary hypertension (30% vs. 91%; P = 0.006) and rehospitalization (7% vs. 73%; P < 0.001) were significantly lower in the operated patients. The 1-year survival rate among the entire study population was 85.7%.

Purpose: As refractoriness of cardiac tissues depends on prior cycle length, refractory periods should be determined at a fixed cycle length within the physiologic range. The extrastimulus is delivered after a train of 8 to 10 paced complexes to allow time for reasonable stabilization of refractoriness, which is usually accomplished after the first 3 or 4 paced beats. Objectives: We conducted this study to compare the effect of 6 vs 8 stimuli in basic cycle length (BCL) in measurement of effective refractory period (ERP). Materials and Methods: During electrophysiologic study (EPS) of 100 consecutive patients, anterograde and retrograde ERP of atrioventricular node (AVN) were measured by introduction of 6 vs 8 stimuli in BCL and premature beat, then the results were compared. Results: Recorded anterograde and retrograde ERP of AVN applying 6 vs 8 stimuli in BCL were compared and no difference was detected. Conclusion: We concluded that for ERP measurement of AVN, 6 stimuli in BCL is comparable to 8 stimuli in reaching the steady state.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":"10 1","pages":"37 - 39"},"PeriodicalIF":0.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46964551","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}

This study aimed to determine the normal ranges of echocardiographic systolic and diastolic values and the incidence of valvular heart lesions with or without rheumatic involvement in a sample of Iranian population. Methods: The Echocardiography Heart Assessment and Monitoring in Rajaie Hospital study is a population-based investigation conducted in Rajaie Cardiovascular Medical and Research Center. A total of 2229 Iranian individuals between 30 and 75 years of age without clinical cardiovascular diseases were invited through a multistage random sampling process, and they underwent two-dimensional and Doppler echocardiography. The left ventricular (LV) ejection fraction, the interventricular septal thickness, the ascending aortic size, the LV diastolic function, the valvular heart disease (VHD) severity, and rheumatic valvular involvement were assessed. Results: The study population comprised 2229 patients: 882 men (40%) and 1347 women (60%) at an age range of 39–58 years and a mean age of 48 years. The average body mass index was 28.8 kg/m2 (25.9–32 kg/m2), and the median body surface area was 1.86. Mildsystolic dysfunction was reported in 119 patients (5.7%) and moderate systolic dysfunction in 19 (0.9%). LV systolic dysfunction was significantly correlated with the male sex, age, and hypertension (P &lt; 0.001). The mean interventricular septal thickness was 8 mm. Mild LV hypertrophy (LVH) was detected in 5.5% of all the patients and moderate LVH in 0.4%. The mean interventricular septal thickness significantly increased with age (P &lt; 0.001), and it was higher in the men than in the women (8.2 mm [7.8–9.2] vs. 8 mm [7–8.25]; P &lt; 0.001). Mild LVH and moderate LVH were significantly correlated with hypertension, diabetes mellitus, hyperlipidemia, chronic kidney disease, and diastolic dysfunction (P &lt; 0.001). Diastolic dysfunction was found in 29% of the patients (28.6% mild and 0.2% moderate). Significant correlations were found between LV diastolic dysfunction and age, the female sex, diabetes mellitus, hypertension, hyperlipidemia, and hypercholesterolemia (P &lt; 0.001). The mean ascending aortic size was 31 mm in the men and 29 mm in the women. The ascending aortic size exceeded 37 mm in 5% of the men and 3.5% of the women. The indexed ascending aortic size was 1.54 cm/m2 in the men and 1.66 cm/m2 in the women. Valvular heart lesions were diagnosed in about half of the study population. The most common findings were mild regurgitation in the mitral and tricuspid valves. Multiple valvular disorders were found in 55% of the patients. Among significant (moderate and more-than-moderate) VHDs, tricuspid regurgitation (36%), mitral regurgitation (33%), and aortic regurgitation (19%) were the most f","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":"10 1","pages":"45 - 53"},"PeriodicalIF":0.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42716818","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}

Materials and Methods: We studied the admission ECG, clinical records, and coronary angiography of 201 patients with STEMI who underwent primary PCI within the first 12 h of symptoms. Patients with first episode of STEMI and coronary angiogram showing coronary artery disease between January 2015 and July 2016 were included in this study. Results: Most of the patients in this study were males (82.1%). The mean age of the patients was 55.20 ± 11.79 years. Diabetic mellitus (37.8%), hypertension (37%), and smoking (49.7%) were the main risk factors. This study had 117 (58.2%) patients of anterior wall myocardial infarction (MI) (Group I) while inferior wall MI was present in 84 (41.8%) patients (Group II). In Group I, 83 (70.9%) patients had single-vessel disease (SVD) while 34 (29.1%) patients had multivessel disease (MVD). The presence of ST-segment depression ≥0.1 mV in leads I, aVL, and V6 significantly correlated with the presence of MVD (P = 0.001, 0.001, and 0.001, respectively).
