The ratio of the maximal possible coronary blood flow to the resting coronary blood flow is termed “the coronary flow reserve” (CFR), which may be assessed noninvasively via dipyridamole stress echocardiography (DSE). Ranolazine is an anti-ischemic agent whose effect on the coronary flow is poorly known. Purpose: We sought to assess temporal variations in the CFR after and before ranolazine administration in a real clinical practice setting among patients with angina and non-obstructive epicardial coronary artery disease. Methods: Seven patients were enrolled, and their demographic, electrocardiographic, and laboratory data were recorded. The CFR was calculated in the anterior descending coronary artery. The definition of abnormal microcirculation was a cutoff value under 2.5. Treatment lasted for 3 months, after which time the same response variables as before were recorded. A general linear model was used to assess whether there was a difference between the preand post-administration of ranolazine. Results: Seven patients were evaluated. At follow-up, there was no discontinuation or side effect. The CFR significantly increased with time (F1,6 = 6.909; P = 0.039). Initially, the mean (± 1 SD) value was 1.85 (±0.34), which rose up to 2.21 (±0.31) after the 3-month treatment period. Conclusions: Ranolazine might have beneficial effects on the CFR as assessed by DSE in patients with angina and non-obstructive epicardial coronary artery disease.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134364262","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 aim of this study was to evaluate and compare the LVEF and mitral regurgitation (MR) severity as estimated by angiography and echocardiography in patients with coronary artery disease (CAD) and LV systolic dysfunction. Methods: In this observational study, 39 men and 11 women at a mean age of 60 years were recruited. The patients underwent catheterization and echocardiography, and the data on the LVEF and MR by both methods were registered. Results: The mean LVEF by echocardiography and angiography was significantly correlated (correlation coefficient = 0.698; P < 0.0001). Although there was agreement between these methods in the estimation of the mean EF (mean difference in the LVEF = 1.23 ± 7.63% and 95% limit of agreement = −12.5–19) and the κ coefficient was 45.7% (P = 0.001), the estimated mean EF was 32.6 ± 10.25% by echocardiography and 29.8 ± 8.2% by angiography (P = 0.007). Furthermore, there was a statistically significant difference in the estimated MR severity between the two methods (P = 0.0001), with echocardiography reporting higher degrees of severity than angiography. Conclusions: In our patients with CAD and LV systolic dysfunction, after the exclusion of age, sex, number of diseased coronary arteries, and myocardial infarction history from the analysis, although the mean LVEF by echocardiography and angiography was significantly correlated, echocardiography estimated higher LVEF values than angiography, especially in the patients with triple-vessel disease. Moreover, echocardiography showed higher degrees of MR severity than angiography.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126442589","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}

Using a high-pitch spiral dual-source computed tomography (DSCT) protocol for left atrial (LA) mapping, we sought to determine IQ and radiation dose in patients with atrial fibrillation scheduled for radiofrequency ablation. Methods: Fifty-nine patients (29 women; mean age = 53 y) underwent CT angiography between 2013 and 2016: 26 patients with retrospective ECG-gated (classic) and 33 with high-pitch (Flash) protocols on a second-generation 128-DSCT system (SOMATOM Definition Flash). CT images of the LA were integrated into an electroanatomic system (NavX). Two independent blinded readers evaluated IQ using a 3-point scale and the LA contrast density. Dose-length product (DLP) was obtained from each patient protocol, and effective radiation dose (ERD) was calculated according to the European guideline for CT. Results: The rate of diagnostic IQ (score 3 or 2) was 87.9% for the flash group and 96.2% for the classic group, which was not significantly different between the 2 groups (P = 0.250). The results of objective IQ measurements showed that a central LA contrast density above 350 Hounsfield units (diagnostic) was present in 21 (80.8%) images in the classic group and 26 (78.8%) images in the flash group, which was not statistically different between the 2 groups (P = 0.850). There were significant differences (P < 0.001) in DLP and ERD between the 2 groups: the values were lower in high-pitch scan than in retrospective ECG-gated scan (151.30± 39.44 vs. 776.61 ± 243.63 and 2.11 ± 0.55 vs. 10.872 ± 3.41, respectively). Conclusions: High-pitch (Flash) DSCT is an acceptable CT angiography method for reducing radiation dose without compromising IQ for LA and pulmonary venous imaging in patients with atrial fibrillation.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"86 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126092166","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}
