Ischemic stroke is a rare and serious complication of coronary angiography and percutaneous coronary intervention, which has high morbidity and mortality. To our knowledge, there is no large-scale randomized controlled trial for the management of catheter-related ischemic stroke. In this case study, we presented a 46-year-old male with peri-procedural ischemic stroke during the coronary angiography (CAG). The CAG was terminated after the stroke and the left carotid artery was selectively cannulated, and digital subtraction angiography (DSA) revealed total occlusion (Modified Thrombolysis in Cerebral Infarction, mTICI, 0) of the M1 part of the left middle cerebral artery (MCA). A stent-assisted thrombectomy was performed and the DSA revealed restoration of flow to the left MCA with mTICI 3 flow in the distal branches. The next day, the neurological exam showed no sensory, motor deficits. The patient was discharged four days later. In the setting of catheter-related stroke, mechanical thrombectomy seems to be the least time-consuming and effective approach.

OBJECTIVE: Although the underlying mechanism is not yet fully understood, Cardiac Syndrome X (CSX) is defined as microvascular dysfunction. Prolidase plays a role in collagen synthesis. Increased serum prolidase activity (SPA) has been shown to correlate with collagen turnover. Augmented collagen turn-over may be associated with vascular fibrosis and microvascular dysfunction. In this study, we assessed whether there was a correlation between CXS and prolidase activity. METHODS: This case-control study included 45 consecutive CSX patients (mean age 50.7+-6.5 years, 27 women) and 40 healthy controls (mean age 51.2+-6.5 years, 25 women). Prolidase activity was determined with the Human Xaa-Pro Dipeptidase/Prolidase enzyme-linked immunosorbent assay kit (Cusabio Biotech Co. Ltd, China). RESULTS: Mean prolidase activity was 898.8+-639.1 mU/mL in the CSX group and 434.1+-289.8 mU/mL in the control group (p

Objective: The evolution of non-vitamin K antagonist anticoagulants (NOACs) has changed the horizon of stroke prevention in atrial fibrillation (SPAF). All 4 NOACs have been tested against dose-adjusted warfarin in well-designed, pivotal, phase III, randomized, controlled trials (RCTs) and were approved by regulatory authorities for an SPAF indication. However, as traditional RCTs, these trials have important weaknesses, largely related to their complex structure and patient participation, which was limited by strict inclusion and extensive exclusion criteria. In the real world, however, clinicians are often faced with complex, multimorbid patients who are underrepresented in these RCTs. This article is based on a meeting report authored by 12 scientists studying atrial fibrillation (AF) in diverse ways who discussed the management of challenging AF cases that are underrepresented in pivotal NOAC trials. Methods: An advisory board panel was convened to confer on management strategies for challenging AF cases. The article is derived from a summary of case presentations and the collaborative discussions at the meeting. Conclusion: This expert consensus of cardiologists aimed to define management strategies for challenging cases with patients who underrepresented in pivotal trials using case examples from their routine practice. Although strong evidence is lacking, exploratory subgroup analysis of phase III pivotal trials partially informs the management of these patients. Clinical trials with higher external validity are needed to clarify areas of uncertainty. The lack of clear evidence about complex AF cases has pushed clinicians to manage patients based on clinical experience, including rare situations of off-label prescriptions.

Background and Objectives: Vasovagal syncope (VVS) is the most common cause of syncope and has multiple pathophysiological mechanisms. Asymmetric dimethylarginine (ADMA) is the major inhibitor of nitric oxide (NO). In this study, we aimed to investigate the relationship between plasma ADMA levels and syncope during the head-up tilt (HUT) test. Materials and Methods: Overall, 97 patients were included in this study. They were above 18 years of age and were admitted to our clinic with the complaint of at least one episode of syncope consistent with VVS. The HUT test was performed in all patients. Patients were divided into the following two groups based on the HUT test results: group 1 included 57 patients with a positive HUT test and group 2 included 35 patients with a negative HUT test. Blood samples were taken before and immediately after the HUT test to measure ADMA levels. Results: No significant intergroup differences were observed concerning gender and age (female gender 68% vs 60%; mean age 24.85 ± 4.01 vs 25.62 ± 3.54 years, respectively, for groups 1 and 2). ADMA values were similar between groups 1 and 2 before the HUT test [ADMA of 958 (544−1418) vs 951 (519−1269); p = 0.794]. In the negative HUT group, no significant differences were observed in ADMA levels before and after the HUT test [ADMA of 951 (519−1269) vs 951 (519−1566); p = 0.764]. However, in the positive HUT group, ADMA levels were significantly decreased following the HUT test [pretest ADMA of 958 (544−1418) vs post-test ADMA of 115 (67−198); p < 0.001]. Conclusion: ADMA levels significantly decreased after the HUT test in patients with VVS.

Ventricular hypertrabeculation/noncompaction is a morphologic and functional anomaly of myocardium characterized by prominent trabeculae accompanied by deep recessus. Dilated cardiomyopathy with left ventricular failure is observed in these patients, while the cause or pathophysiologic nature of this complication is not known. Anti-troponin antibodies are formed against circulating cardiac troponins after an acute coronary event or conditions associated with chronic myocyte necrosis, such as dilated cardiomyopathy. In present study, we aimed to investigate cardiac troponins and anti troponin autoantibodies in ventricular noncompaction/hypertrabeculation patients with/without reduced ejection fraction. A total of 50 patients with ventricular noncompaction and 23 healthy volunteers were included in this study. Noncompaction/hypertrabeculation was diagnosed with two-dimensional echocardiography using appropriate criteria. Depending on ejection fraction, patients were grouped into noncompaction with preserved EF (LVEF >50%, n = 24) and noncompaction with reduced EF (LVEF

Summary: Background and aims: Patients with inflammatory bowel disease (IBD) are at increased risk for coronary artery disease (CAD), even after adjusting for traditional risk factors for atherosclerosis. While inflammation is widely regarded as the pathophysiologic link between IBD and CAD, the exact mechanisms are largely unknown. This study was conducted to investigate the association of lipid parameters and indices with coronary flow reserve and markers of inflammation in IBD patients. Methods: A total of 73 patients with IBD and 26 healthy controls were enrolled. Patients in the IBD arm were either in remission or had mild disease activity. Lipid parameters, C‑reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were analyzed using standard laboratory techniques. Coronary flow reserve (CFR) was measured using two-dimensional echocardiography. Results: Both CRP and ESR were higher and CFR was significantly lower in IBD patients, but there were no differences in terms of lipid parameters or indices; however, patients with IBD and a CFR <2.0 had significantly higher triglyceride (TG) level (155.0 (80.0) mg/dl vs. 108.0 (68.0) mg/dl, p < 0.001) and there was a strong trend towards lower high-density lipoprotein (HDL) cholesterol (40.0 (8.5) mg/dl vs. 45.0 (10.0) mg/dl, p = 0.05) level in the latter group when compared to patients with a CFR ≥2.0. The atherogenic index of plasma (AIP), measured as log(TG/HDL-C) had the best predictive value for CFR in IBD group and was an independent predictor of CFR after multivariate adjustment for confounders (unstandardized coefficient: −0.75, 95% CI: (−1.13)–(−0.37)), β = −0.41, p = <0.001). Conclusion: The atherogenic index of plasma is a marker for reduced CFR in IBD patients and could be useful to screen those at risk for early atherogenesis and CAD. [ABSTRACT FROM AUTHOR]
