Painful left bundle branch block: A syndrome with a particular clinical significance.

The development of angina in the setting of new-onset left bundle branch block (LBBB) that resolves at the same time with the disappearance of LBBB, without coexistent myocardial ischemia, denotes the painful LBBB syndrome. In this illustrative case report we describe a young male patient with painful LBBB syndrome. The LBBB was rate-dependent occurring during exercise and the patient was successfully treated with bisoprolol.

The TRACE registry (Trans-Radial Approach in Central and northErn Greece).

Objective: We examined trans-radial approach (TRA) use in coronary angiographies (CAs) as well as in percutaneous coronary interventions (PCIs) in specific regions of Greece, its distribution in public and private catheterization laboratories (CLs) and its preference by operators. Reliable data regarding the use of TRA are not available in Greece.

Methods: The study was performed in northern and central Greece, which constitutes 35.

Acute non-ST-elevation myocardial infarction presented as occipital headache with impaired level of consciousness--a case report.

Headache represents a rare manifestation of myocardial ischemic pain. It is believed that this clinical symptom results from convergence of heart autonomic fibers with somatic inputs originating from the head. The authors describe for the first time the case of a 73-year-old woman who experienced an acute non-ST-elevation myocardial infarction that manifested solely with intense occipital headache associated with vomiting and impaired level of consciousness.

Oral vitamin C administration reduces early recurrence rates after electrical cardioversion of persistent atrial fibrillation and attenuates associated inflammation.

Background: Inflammation and oxidative stress have been recently implicated in the pathophysiology of atrial fibrillation (AF). The aim of this study was to examine the potential benefit of vitamin C on the early recurrence rates and on inflammatory indices after successful cardioversion of persistent AF, as well as to investigate the time course of changes in these indices post-cardioversion.

Methods: We prospectively studied 44 consecutive patients after successful electrical cardioversion of persistent AF.

Kearns-Sayre syndrome associated with trifascicular block and QT prolongation.

Patients suffering from Kearns-Sayre syndrome (KSS) often develop conduction defects that may lead to syncope or sudden cardiac death. The association of conduction abnormalities with prolonged QT interval in these patients is very rare. We describe a patient with KSS and diabetes mellitus who suffered a torsades de pointes-induced syncopal attack, in the presence of trifascicular block and QT prolongation (QTc: 574 ms).

Acute low back pain during intravenous administration of amiodarone: a report of two cases.

Amiodarone represents an effective antiarrhythmic drug for cardioversion of recent-onset atrial fibrillation (AF) and maintenance of sinus rhythm. We briefly describe two patients suffering from recent-onset atrial fibrillation, who experienced an acute devastating low back pain a few minutes after initiation of intravenous amiodarone loading. Notably, this side effect has not been ever reported in the medical literature.

QRS dispersion: an electrocardiographic index of systolic left ventricular dysfunction in patients with left bundle branch block.

The presence of complete left bundle branch block (LBBB) in patients with congestive heart failure has been proposed to be a factor that negatively affects left ventricular (LV) systolic function. The aim of this study was to evaluate the relative predictive value of QRS dispersion (QRSD) and QRS duration (QRSd) in relation to systolic performance of the left ventricle. The ejection fraction of 130 consecutive patients with LBBB was evaluated by standard echocardiographic methods, whereas QRSd and QRSD were measured.

Combination of traumatic pseudoaneurysm of descending thoracic aorta and bicuspid aortic valve endocarditis in a young adult.

We report on a 26-year-old man who injured in an automobile accident and developed post-traumatic bicuspid aortic valve endocarditis associated with severe regurgitation. In addition, transesophageal echocardiography (TEE) revealed a pseudoaneurysm of the descending thoracic aorta. The combination of medical and surgical therapy led to a favorable outcome.

Usefulness of predischarge exercise electrocardiographic testing in detecting the late patency status of the infarct-related artery.

Predischarge exercise electrocardiographic testing (PEET) represents a widely accepted clinical tool for prognostic and functional assessment of patients who experience an uncomplicated acute myocardial infarction (AMI). However, there are no data suggesting any relation between PEET results and patency status of the infarct-related artery (IRA). The aim of this study was to investigate whether ST and/or QT-dispersion (QTD) changes induced by a low-level PEET, after uncomplicated ST-elevation AMI, are related to the late patency status of the IRA.
