Comparative StudyAcute anterior wall myocardial infarction entailing ST-segment elevation in lead V1: electrocardiographic and angiographic correlations.
The correlation between ST elevation in lead V1 during anterior wall acute myocardial infarction (AMI) and the culprit lesion site in the left anterior descending (LAD) coronary artery is poor. ⋯ ST-segment elevation in lead V1 during first anterior wall AMI was found in one third of the patients, and its magnitude was lower than that in the other precordial leads. ST-segment elevation in lead V1 favors the presence of a small conal branch of the RCA that does not reach the IVS.

Review Case ReportsTiclopidine-induced neutropenia mimicking sepsis early after intracoronary stent placement.
We report a case of ticlopidine-induced profound neutropenia early in the course of therapy, which was manifest as a febrile systemic illness mimicking sepsis. This clinical presentation was potentially indicative of a contaminated intracoronary stent. The patient's signs and symptoms of illness promptly resolved with removal of ticlopidine, and no infection was documented. Review of indications for ticlopidine use, potential adverse effects, and monitoring recommendations are discussed.

Comparative StudyLong-term outcome of spinal cord electrical stimulation in patients with refractory chest pain.
Treatment of patients with refractory chest pain remains a challenge. In this study, the long-term clinical effects of spinal cord electrical stimulation were evaluated in 10 consecutive male patients (mean age 53.7 years) with chronic chest pain in a prospective observational study. ⋯ Spinal cord electrical stimulation is one of the few therapeutic options in inoperable patients with refractory chest pain.

Case ReportsLeft ventricular diastolic collapse in low-pressure cardiac tamponade.
A case of systemic hypotension with volume depletion not responding to intravenous fluids was found to have features of cardiac tamponade on two-dimensional (2-D) echocardiography. Intracardiac pressures were normal on cardiac catheterization. An interesting observation was the presence of left ventricular (LV) collapse on 2-D echocardiography. To the authors' best knowledge, such a case of low pressure cardiac tamponade with LV collapse has not been reported earlier.

Validation of a decision support tool for the evaluation of cardiac arrest victims.
There is currently no well-accepted model for early and accurate prediction of neurologic and vital outcomes after cardiac arrest. Recent studies indicate that individuals with acute myocardial ischemia as the etiology for the arrest may benefit from early revascularization. ⋯ The cardiac arrest score is a valid decision support tool in the evaluation of cardiac arrest victims. Patients with the most favorable scores may be considered for early angiography and revascularization if myocardial ischemia is the etiology of the arrest.
