Materials and Methods: Thirty male rats were randomly assigned into the sham (SM), femoral artery resection (FE), constrictor-induced ischemia (CI), two-stage ischemia (TS), or diabetic two-stage ischemia (DT) groups. In the FE group, rats underwent femoral artery resection, whereas the SM group had sham surgery. The CI group received progressive ischemia using two ameroid constrictors, and the TS and DT groups underwent a two-stage ischemia procedure involving initial gradual narrowing with two ameroid constrictors and subsequent femoral artery resection in healthy and diabetic rats, respectively. Perfusion evaluation and functional assessment were conducted at postoperative days 14, 28, and 42. On day 42, hypoxia-inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) protein expression were measured, along with histological examination and immunofluorescence analysis. Results: Motor function deficits and reduced limb reperfusion were most prominent in the TS and DT groups on days 28 and 42 (P < 0.05), exacerbated by type 2 diabetes. Gastrocnemius exhibited upregulated HIF-1α and VEGF protein expression, as well as increased capillary density in response to ischemia. However, the DT group showed significantly lower protein expression and capillary density, along with more severe structural damage compared to other groups (P < 0.05). Conclusion: A clinically relevant rat model of PAD was established by implementing a two-stage ischemia procedure involving initial progressive narrowing and subsequent femoral artery excision in the context of diabetes.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136208381","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}

Therefore, in the present study, lifetime risk of ASCVD was calculated in an urban cohort. White-collar employees have higher risk of developing cardiovascular disease events because of their work profile. Aim and Objectives: To calculate lifetime predicted risk of ASCVD among study cohort and to explore factors contributing to the disparities of cardiovascular risks. Materials and Methods: This was community-based cross-sectional study. The baseline data were collected during the period 2016–2019 from Rajkot city, and their lifetime predicted risk of ASCVD was calculated using ASCVD risk calculator. Crude and adjusted prevalence ratio was calculated. Results: The study revealed that 69.25% and 6.37% of participants had low and intermediate lifetime predicted risk of ASCVD, respectively, while the remaining 16.12% and 8.25% had borderline and high risk, respectively. Conclusion: This study indicates that increased lifetime predicted risk of ASCVD was associated with increasing age, male, stress, elevated blood pressure, high level of body mass index, and central obesity among participants.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48665301","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}

Moreover, this technique can be practically applied to other types of anatomical variations around the bifurcation. Case 1 was that of a 53-year-old man with a tight stenosis of the proximal left anterior descending artery at the diagonal bifurcation with angiographically apparent coronary dissection. We successfully achieved guidewire insertion into the targeted branch using the DLC-facilitated reverse wire technique. Case 2 involved a 78-year-old man with total occlusion of the mid-portion of the right coronary artery. The guidewire reentry point in the atrioventricular branch was slightly distant from the true distal end of the occlusion. We successfully used the DLC-facilitated reverse wire technique to pass a second guidewire to the posterodescending artery. Case 3 was that of an 80-year-old man whose coronary artery had an aneurysm with severe stenoses at both entry and exit of the aneurysm. We adopted the DLC-facilitated reverse wire technique and easily advanced the guidewire by matching the guidewire advancing path with the direction of the sequential conduit constituted by the coronary aneurysm and stenosis. The timing of decision-making to try the DLC-facilitated reverse wire technique is important. The lesion for which reverse wiring is suitable is usually difficult to be treated with conventional guidewire crossing. We have to promptly judge the validity of applying this technique based on the angiographic findings of targeted lesions and take immediate action to implement this procedure to reduce the procedural time and irradiation dose.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49202343","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: This current cross-sectional study was conducted with 155 patients with β-thalassemia major and thalassemia intermedia referring to Razi Hospital Rasht, Iran in a recent year. All patients underwent echocardiography and the data (including age, sex, thalassemia type, splenectomy history, deferoxamine usage, hydroxyurea usage, hemoglobin, and ferritin level) were collected by a researcher-made checklist. Data analysis was performed using SPSS software. Results: The prevalence of PH was 13.7% in this study. There was a correlation between sex, thalassemia type, deferoxamine usage, and ferritin level with a prevalence of PH. However, there was not a significant relationship between splenectomy history, hydroxyurea usage, and hemoglobin level with PH prevalence (P = 0.187, P = 0.035, and P = 0.178, respectively). Conclusions: The findings of the study represented that the proposed variables can cause and exacerbate cardiac complications and may have a correlation with the disease's side effects. By conducting more studies and designing a more promising interventional study with a higher sample size, using the results of this study and similar studies, a step could be taken to identify patients susceptible to exacerbation of cardiac complications earlier. By treating them, we may be able to increase their chance of survival in the long run.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42185526","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}

Aims: We aimed to study the short-term outcomes of primary PCI at a large tertiary care center in India. Settings and Design: A prospective cohort of patients with ST-elevation myocardial infarction (STEMI) who underwent primary PCI was enrolled between December 2015 and November 2016. Subjects and Methods: The demographic profile, risk factors, clinical characteristics, inhospital complications, and outcomes at 30 days were assessed. The primary outcome was a composite of death, reinfarction, and repeat revascularization. Acute left ventricular failure (LVF), complete heart block (CHB) or bradyarrhythmia, ventricular tachycardia (VT) or ventricular fibrillation, stroke, and major thrombolysis in myocardial infarction bleeding were the inhospital complications that were considered the secondary outcomes. Results: A total of 237 STEMI patients with primary PCI were enrolled, accounting for 7.5% of all PCI procedures performed during this period. The mean age was 55.4 ± 11.9 years, and 86.5% were male. The mean window period was 5.1 ± 3.18 h, and the mean door-to-balloon time was 58.4 ± 11.5 min. Prior to PCI, the most often administered antiplatelets were clopidogrel in 54.4% of patients and prasugrel in 55.6%. The aspiration thrombectomy was done in 70.8% of patients. Predilatation with balloon was required in 41.8% of patients. Drug-eluting stents were implanted in 98.3% of patients. The primary outcome was found in 3.3% of patients (deaths – 2.9% and reinfarction – 0.4%) and the secondary outcomes were observed in 13%. The common inhospital complication was CHB or bradyarrhythmia in 5.0% followed by acute LVF in 4.6% and then VT in 2.1%. Conclusions: The primary outcome rate is as good as reported in developed Western countries in contemporary treatment practices of STEMI. CHB and acute LVF were the major inhospital complications among patients of STEMI treated with primary PCI.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46314810","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}

We evaluate the frequency of aortic root dilation in adult TFTC patients and analyze probable risk factors related to the dilated aortic root. Materials and Methods and Results: We reviewed echocardiography images of 146 adult TFTC patients who admitted at Rajaie Cardiovascular Medical and Research Center from 1383 to 1399 in an observational retrospective cohort study. Sinus of Valsalva (SOV) was measured in parasternal long-axis view. Aortic root dilation was determined by two definitions. When we adjusted SOV diameter for body surface area and sex, the frequency of aortic root dilation was 68%, with a mean SOV diameter of 3.5 ± 0.7 cm and when we used absolute diameter ≥4 cm for dilated SOV, 22% showed aortic root dilation. By multivariate logistic regression analysis, male sex (odds ratio (OR) = 3.47, P = 0.003), age at the time of TFTC (OR = 1.06, P = 0.009), and aortic regurgitation (OR = 3.97, P = 0.003) were associated with increased adds of dilated aortic root. Three patients underwent aortic surgery, including one case of type A aortic dissection.

Among streptococci, the viridans group streptococci are responsible for a considerable percentage of all IE cases. Methods: Since 2006, the Iranian Registry of Infective Endocarditis has recorded information regarding all adult patients with a definite or possible IE diagnosis according to the modified Duke criteria. Patients with viridans streptococcal endocarditis were detected through three blood culture sets. The patients' demographic characteristics, predisposing factors, clinical presentations, and echocardiographic findings were recorded. Results: Of 731 patients diagnosed with endocarditis, viridans streptococci were found in 46 (6.3%) patients, consisting of 28 (60.9%) men and 18 (39.1%) women at a mean age of 42.56 ± 15.46 years, who were subsequently included in the study. Among the 46 patients with viridans streptococcal endocarditis, 26 had a subacute course, whereas 20 had an acute course. Vegetation was detected in 35 patients. All the patients were treated with the standard antibiotic regimen for viridans streptococcal endocarditis, and cardiac surgery was performed on 16 patients. Conclusions: Clinicians should pay sufficient heed to the following points in all cases of viridans streptococcal endocarditis: firstly, an appropriate antibiotic regimen must be based on a precise minimal inhibitory concentration determination for the usual antibiotics. Secondly, since prolonged antibiotic therapy is crucial to the eradication of microorganisms within vegetation, all patients with viridans streptococcal endocarditis must receive an adequate therapy course.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41892384","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}
