ABSTRACT

Electrical storm is a life-threatening medical emergency that requires immediate diagnosis and treatment. It can remain a clinical challenge despite anti-arrhythmic drugs and catheter ablation therapies. Autonomic modulation techniques have gained increased recognition in the treatment of refractory electrical storm cases. In our case, we present a patient with recurrent ventricular tachycardia/fibrillation episodes one week after a myocardial infarction. Patient's arrhythmia was refractory to antiarrhythmic drugs and hemodynamical status was unstable, thus catheter ablation under temporary mechanical circulatory support was the initial strategy. Ventricular fibrillation episodes relapsed 48 h after catheter ablation and we proceeded with autonomic modulation treatment options. Bilateral stellate ganglion blockade was performed under ultrasound guidance using bupivacaine. Sinus bradycardia was present and no ventricular arrhythmias were detected on post-procedure ECG. Stellate ganglion blockade was complemented with video-assisted thoracoscopic cardiac sympathetic denervation. After the last procedure, patient remained on sinus rhythm, was hemodynamically stable and extubated successfully.

ABSTRACT

AIMS: Statins have favourable effects on the vascular system. However, few data are available regarding the effect of these drugs on patients undergoing percutaneous coronary intervention (PCI). We sought to determine the impact of prior statin use on coronary blood flow after PCI in patients with stable coronary artery disease (CAD) by using the corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC). METHODS: A total of 80 consecutive eligible patients (mean age: 60 ± 7 years, 65 % male) with the diagnosis of stable CAD who were hospitalised for elective PCI were retrospectively enrolled in our study. The study population was divided into two groups according to statin use at least 6 months before PCI. Group 1 comprised of 51 patients (67 % male; mean age: 58 ± 4 years) taking statins and group 2 comprised of 29 patients (62 % male; mean age: 60 ± 3 years) not taking statins. PCI was applied to de novo type A lesions. CTFC was calculated for the treated vessels at baseline and after PCI. RESULTS: The two groups had similar characteristics in terms of age, sex, concomitant medications, lesion characteristics, pre-procedural CTFC, lipid parameters, and risk factors for CAD. Post-PCI CTFC (16 ± 3 vs. 22 ± 5, p = 0.01) and hs-CRP (2.1 ± 0.7 mg/l vs. 6.1 ± 2 mg/l, p = 0.01) in patients receiving statins before PCI were significantly lower than in patients without statin therapy. Multiple logistic regression analysis showed that statin pre-treatment (OR 2.5, 95 % CI 1.2 to 3.8, p < 0.001) and hs-CRP level (OR 1.8, 95 % CI 1.2 to 2.4, p = 0.001) were independent predictors of post-PCI CTFC. CONCLUSIONS: In patients with stable CAD undergoing PCI, receipt of long-term statin therapy was associated with improvement in epicardial perfusion after PCI.

ABSTRACT

Background: Vitamin D deficiency is associated with many diverse cardiovascular disorders, such as hypertension, heart failure, stroke, coronary artery disease and atrial fibrillation. The relationship between Vitamin D and the development of atrial fibrillation after coronary artery bypass surgery (CABG) has not been studied. Therefore, we assessed the relationship between Vitamin D and the development of postoperative atrial fibrillation (POAF) after CABG.Methods: Medical records of consecutive patients who underwent CABG surgery were retrospectively reviewed for the development of atrial fibrillation in the postoperative period. Vitamin D, other biochemical parameters, and clinical and echocardiographic parameters were evaluated in all patients. The independent variables for the development of postoperative atrial fibrillation were defined and their predictive values were measured. Results: The study group consisted of 128 patients, of whom 41 (32%) developed POAF. Age, diabetes mellitus, chronic obstructive pulmonary disease, history of transient ischaemic attack/stroke, heart failure, left atrial diameter, platelet:largecell ratio, and creatinine, urea, uric acid, calcium and potassium levels were identified as important variables for the development of POAF. However, with logistic regression analysis, chronic obstructive pulmonary disease (OR: 28.737, 95% CI: 0.836­16.118, p < 0.001), heart failure (OR: 15.430, 95% CI: 0.989­7.649, p = 0.006), diabetes mellitus (OR: 11.486, 95% CI: 0.734­11.060, p = 0.001) and left atrial diameter (OR: 1.245, 95% CI: 0.086­6.431, p = 0.011) appeared as independent variables predicting the development of POAF.Conclusion: In our study, although there was a significant negative correlation between Vitamin D and left atrial diameter, Vitamin D level was not an independent predictor for POAF

ABSTRACT

OBJECTIVE: The SYNTAX Score was recently developed to characterize the coronary vasculature with respect to the number of lesion's location, complexity, and functional impact and it is a quantitative scoring system to assist with patient selection for optimal revascularization strategy between percutaneous coronary intervention (PCI) and coronary artery by-pass surgery (CABG). b2-glycoprotein I (b2GPI), a plasma protein that binds cardiolipin, acts as a modulator of platelet aggregation and coagulation. Antibodies to b2GPI may have a role in atherosclerosis by inducing endothelial cell activation. We investigated the relationship between anti beta 2 GPI and severity of coronary artery stenosis by calculating the SYNTAX Score among patients undergoing CABG surgery. PATIENTS AND METHODS: We prospectively investigate 612 patients who undergo elective coronary angiography between September 2012 and June 2013. Patients were evaluated for blood chemistry and anti-b2GPI IgA, IgM and IgG. Ninety seven patients with complete biochemical analysis including anti Beta 2 GPI antibodies and undergone CABG have been enrolled in this study. We divided patients in to 2 groups according to the SYNTAX scores. Group 1 included 48 patients with low SYNTAX scores (<23) and group 2 included 49 patients with intermediate and high SYNTAX scores (>23). RESULTS: There was significant correlation between elevated anti b2GPI IgG levels and higher SYNTAX score which indicate advanced and complex CAD. In this study, lesion complexity increased progressively with increasing anti-b2GPI-IgG type of antibody levels. According to this findings, anti-b2GPI-IgG is a strong predictor of higher SYNTAX score. CONCLUSIONS: In addition to the traditional risk factors for atherosclerosis, the proinflammatory and procoagulant activities of antiphospholipid antibodies appear to be important risk factors for atherosclerotic occlusive disease.
