The selection of treatment is dictated by the severity of PH. The cardiac index (CI) is a robust indicator of PH severity. This trial aimed to find out the association between electrocardiogram (ECG) data and CI as a prognostic factor of PH. Methods: Ninety-five patients with precapillary PH were included in the study. The cardiac output of patients was calculated using the right heart catheterization and the Fick formula. Patients were categorized into low- and high-risk groups based on the CI. Their ECGs were interpreted by an expert cardiologist. The association between ECG parameters and severity of PH was evaluated based on the CI. Results: The median age of patients was 36 years. The mean of CI was 2.35 L/min/m2 with a standard deviation of 0.74. About 36% of patients were in the high-risk category based on the CI. Among ECG parameters, ST segment depression in V1-V6 and R/S ratio ≥1 in V1 were found significantly correlated with CI for high-risk category (P = 0.026). Conclusion: ST segment depression in V1-V6 and R/S ratio ≥1 in V1 had a significant association with CI in the range lower than 2 L/min/m2, which is an indicator of poor PH prognosis. Therefore, these variables can be used as an inexpensive and available prognostic factor in patients with precapillary PH.","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":"44654057","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 growing population of geriatrics in the recent decades in combination with an increase in the prevalence of chronic diseases including diabetes and hypertension are some of the leading causes for an increase in the prevalence of chronic kidney disease and end-stage renal disease (ESRD). The definite treatment for ESRD is renal transplant but unfortunately, it may take a long time to find a suitable kidney and continuing the patient's life may depend on dialysis. Arteriovenous fistula (AVF) formation is one of the first steps to prepare the patient for hemodialysis. ESRD itself is a reason for physical and psychosocial issues. Preparing a favorable condition for AVF surgery is essential to decrease the burden of the underlying disease. An efficient respiratory supply is necessary in all parts of an anesthetic procedures. Aims and Objectives: This study is a double-blind clinical trial to compare two anesthetic agents, dexmedetomidine and remifentanil in patients with ESRD who underwent AVF formation. Materials and Methods: SpO2 was measured on different phases including the time of initial incision, and after 10, 30, 60, 90, and 120 min of finishing the surgery. The data were analyzed using SPSS version 22, two-way repeated measures (ANOVA), and independent t-test. Results: This study showed that there was no any significant difference in using any of these two agents with regard to SpO2 in the different times of measurements during the anesthetic procedure and after the surgery in the recovery phase. Conclusion: This study showed that there is not any superiority in using DEX or REM in the patients undergo AVF formation. More studies on the other groups of the patients with different surgeries.","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":"47248218","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 observational comparative study was done to find the metabolic effects of Ringer lactate and Plasmalyte-A as priming solutions for various metabolic parameters during adult cardiac surgery. Materials and Methods: In the present study, 52 subjects were included who received different priming solutions. Subjects were categorized into two groups. Group P received Plasmalyte-A as prime and Group R received Ringer lactate. From all these cases, samples were collected at predefined time durations, and results were compared between both groups. Observation and Results: A total of 52 patients were evaluated for the metabolic changes concerning different priming solutions. Group P included the subject who received Plasmalyte-A as pump prime (n = 26), and Ringer lactate was used as pump prime in Group R (n = 26). We compared various parameters such as pH: In Group R, a decrease in pH was statistically significant with P < 0.05 at 40 min of bypass (T40) and P < 0.05 at 6 h of postbypass (T6). Base Excess: The mean value in Group P was − 1.72 ± 2.18 and − 3.16 ± 2.48 and in Group R at 30 min of bypass (T30). A statistically significance was found between the two groups for this parameter (P < 0.05). Lactate and Strong Ions Difference: A statistically significant data were found between the two groups for this parameter throughout the bypass as well as postoperative hours with the P < 0.05. Conclusion: Plasmalyte-A is more favorable crystalloid solution as a pump prime fluid as it helped to maintain satisfactory metabolic parameters with less metabolic acidosis during adult cardiac surgeries.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45491597","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}

Bagheri","doi":"10.4103/rcm.rcm_71_21","DOIUrl":"https://doi.org/10.4103/rcm.rcm_71_21","url":null,"abstract":"Background: The intraaortic balloon pump (IABP) is the most common mechanical assist device used as an adjunctive therapy for patients with low cardiac output among cardiac surgery. However, controversy still exists about the optimal time for IABP insertion. The study evaluated the association between timing of IABP insertion and outcome in cardiac surgical patients. Patients and Methods: Patients who underwent cardiac surgery between August 2007 and June 2014 were included. 273 of 3480 patients (7.84%) required perioperative IABP support. Of whom 21 (7.7%) received a preoperative IABP, 180 (65.9%) received an intraoperative IABP and 72 (26.4%) received a postoperative IABP. Predictors of early mortality were measured in stepwise multivariate logistic regression analyses. Results: The overall mortality rate for all patients requiring IABP was 29.3%. The incidence of mortality in patients who underwent pre-, intra- and postoperative IABP insertion was 19.0%, 22.8%, and 48.6%, respectively. The independent predictors of early mortality were age, cross clamp time, and postoperative IABP. However, either pre or intraoperative IABP insertion was not associated with increase in early mortality. Conclusions: IABP treatment in patients undergoing cardiac surgery was relatively safe accompanied by few complications. Timing of IABP insertion appears to be associated with survival as early insertion results are much more desirable compared to postoperative insertion.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48197435","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 aimed to investigate the reasons for seeking cardiology care and to assess our cardiologists' diagnostic approaches to COVID-19 patients with potential cardiovascular involvement. Methods and Results: In this prospective, observational study, data of all consecutive COVID-19 patients admitted to six designated hospitals for COVID-19 in Iran in whom bedside cardiology consultation was requested were collected. A total of 148 patients including 105 (71%) males were included. The mean age was 57 ± 17 years. The most common reasons for cardiology consultation were dyspnea (56.7%), chest pain (12.8%), and suspected arrhythmias (10.8%). The most common comorbidities were hypertension (40.5%), diabetes mellitus (19.6%), and coronary heart disease (18.9%). A 12-lead electrocardiography (ECG) was obtained in all patients. Point-of-care ultrasonography or limited transthoracic echocardiography (TTE) was performed in 106 (71.6%) patients, and complete TTE was performed in 35 (23.4%) patients. Cardiac troponin was measured in 63 (42.6%) patients, and N-terminal pro B-type natriuretic peptide level was measured in 34 (23%) patients. Overall, 51 (34.5%) patients underwent invasive mechanical ventilation, inotropes were used in 29 (19.6%) patients, and 40 (27%) patients died. Conclusions: While preventing unnecessary investigations, the cardiologists should not overlook the lifesaving role of ubiquitous diagnostic modalities (such as ECG and TTE) in early detection and management of cardiac involvement in COVID-19.","PeriodicalId":21031,"journal":{"name":"Research in Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47449134","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}
