Abstract

BACKGROUND AND OBJECTIVES: Mortality in acute coronary syndrome (ACS) patients with ventricular arrhythmia (VA) has been shown to be higher than those without VA. However, there is a paucity of data on VA among ACS patients in the Middle Eastern countries.

DESIGN AND SETTING: Prospective study of patients admitted in 17 government hospitals with ACS between December 2005 and December 2007.

PATIENTS AND METHODS: Patients were categorized as having VA if they experienced either ventricular fibrillation (VF) or sustained ventricular tachycardia (VT) or both.

RESULTS: Of 5055 patients with ACS enrolled in the SPACE registry, 168 (3.3%) were diagnosed with VA and 151 (98.8%) occurred in-hospital. The vast majority (74.4%) occurred in patients with ST-segment elevation myocardial infarction. In addition, males were twice as likely to develop VA than females (OR 1.7; 95% CI 1.13). Killip class >I (OR 2.0; 95% CI 1.3-3.1); and systolic blood pressure <90 mm Hg (OR 6.4; 95% CI 3.5-11.8) were positively associated with VA. Those admitted with hyperlipidemia (OR 0.49; 95% CI 0.3-0.7) had a lower risk of developing VA. Adverse in-hospital outcomes including re-myocardial infarction, cardiogenic shock, congestive heart failure, major bleeding, and stroke were higher for patients with VA (P?.01 for all variables) and signified a poor prognosis. The in-hospital mortality rate was significantly higher in VA patients compared with non-VA patients (27% vs 2.2%; P=.001).

CONCLUSIONS: In-hospital VA in Saudi patients with ACS was associated with remarkably high rates of adverse events and increased in-hospital mortality. Using a well-developed registry data with a large number of patients, our study documented for the first time the prevalence and risk factors of VA in unselected population of ACS.

Abstract
BACKGROUND AND OBJECTIVE: Home intravenous (IV) antibiotic programs are becoming increasingly popular worldwide because of their efficacy and safety. However, in Saudi Arabia these programs have not yet become an integrated part of the health care system. We present our experience with a home IV antibiotic program, as one of the major health care providers in Saudi Arabia.
DESIGN AND SETTING: Retrospective chart review of patients enrolled in the King Abdulaziz Medical City Home Health Care IV Antibiotic Program from 1 May 2005 (the start of the program) until 30 December 2007.
METHODS: In addition to demographic characteristics, we collected data on the site of infection, the clinical diagnosis, the isolated microorganisms, and the type of antibiotics given. Outcome measures evaluated included the relapse rate, failure rate, the safety of the program, and readmission rates.
RESULTS: Of the 155 patients enrolled, 152 patients completed the program. Those who completed the program had a mean (SD) age of 52.8 (23.9) years. The mean (SD) duration of the IV antibiotic treatment was 20.6 (17) days. Three patients refused to complete the intended duration of therapy. Peripherally inserted central catheter (PICC) lines were utilized in 130 patients (86%). One-hundred and thirty-one patients completed the intended duration of therapy, although the therapy was changed from the initial plan for 21 (13.8%) patients. Readmission to the hospital during therapy was required for 13 patients (8.5%). Osteomyelitis was the most frequently encountered diagnosis (65 patients, 42.8%), followed by urinary tract infection (36 patients, 23.7%).
CONCLUSIONS: The home health care-based IV antibiotic program was an effective and safe alternative for in-patient management of patients with non-life-threatening infections, and was associated with a very low complication rate. Home IV antibiotic programs should be used more frequently as part of the health care system in Saudi Arabia.

Electrical cardioversion.

Ann Saudi Med. 2009 May-Jun;29(3):201-6

Authors: Sucu M, Davutoglu V, Ozer O

External electrical cardioversion was first performed in the 1950s. Urgent or elective cardioversions have specific advantages, such as termination of atrial and ventricular tachycardia and recovery of sinus rhythm. Electrical cardioversion is life-saving when applied in urgent circumstances. The succcess rate is increased by accurate tachycardia diagnosis, careful patient selection, adequate electrode (paddles) application, determination of the optimal energy and anesthesia levels, prevention of embolic events and arrythmia recurrence and airway conservation while minimizing possible complications. Potential complications include ventricular fibrillation due to general anesthesia or lack of synchronization between the direct current (DC) shock and the QRS complex, thromboembolus due to insufficient anticoagulant therapy, non-sustained VT, atrial arrhythmia, heart block, bradycardia, transient left bundle branch block, myocardial necrosis, myocardial dysfunction, transient hypotension, pulmonary edema and skin burn. Electrical cardioversion performed in patients with a pacemaker or an incompatible cardioverter defibrillator may lead to dysfunction, namely acute or chronic changes in the pacing or sensitivity threshold. Although this procedure appears fairly simple, serious consequences might occur if inappropriately perfformed.
