Multiple-vein thrombosis and pulmonary embolism after pacemaker implantation treated by thrombolysis.
This report describes a patient who suffered multiple-vein thrombosis following permanent pacemaker implantation and developed a pulmonary embolism while on anticoagulation treatment, which was successfully treated by thrombolytic therapy.

The diagnostic value of QRS changes for prediction of coronary artery disease during exercise testing in women: false-positive rates.
OBJECTIVES: The false positive rate of electrocardiographic exercise testing (ET) for coronary artery disease (CAD) in women ranges from 38 to 67%, using the ST-T changes (ST-T) criteria. The aim of this study was to compare the diagnostic accuracy of QRS duration change criteria with ST-T change criteria during ET. METHODS: We studied 234 women (mean age 58+/-17 years, range 27-83 years), of whom 160 were pre-menopausal (PrMW; mean age 41+/-9, range 27-56) and 74 were post-menopausal (PoMW; mean age 65+/-7, range 57-83). All participants underwent ET to rule out CAD, followed by thallium stress testing (TL). QRS duration, measured with a computerized optical scanner and ST-T changes at peak ET were compared with TL. An ischemic QRS response was defined as an exercise-induced prolongation of QRS duration >3 ms. RESULTS: The sensitivities of QRS duration changes for the entire study group, the PrMW group and the PoMW group in comparison with TL, were 93, 88 and 92%, respectively, while the corresponding rates of specificity were 91, 85 and 91%, respectively. The sensitivities of ET ST-T changes for the entire study group, for the PrMW group and for the PoMW group were 48, 46 and 54%, respectively, while the corresponding rates of specificity were 62, 75 and 79%, respectively. The false-positive rate was 20% for ischemic ST-T and 4% for ischemic QRS duration for the entire study population. CONCLUSIONS: Computer-measured QRS duration changes during ET are more sensitive and specific than ST-T changes for the detection of ischemia in women.

BiPAP ventilation as assistance for patients presenting with respiratory distress in the department of emergency medicine.
BACKGROUND: Noninvasive ventilatory support (NIVS) is intended to provide ventilatory assistance for a wide range of respiratory disturbances. The use of NIVS for treatment of respiratory distress may be applicable in the emergency department (ED). It may prevent endotracheal intubation and, likewise, may favorably influence the course of the patient's hospitalization, depending on the primary disease or ventilatory disturbance. OBJECTIVE: To evaluate the efficacy of bilevel positive airway pressure (BiPAP) ventilation in patients with acute respiratory distress presenting in the ED. METHODS: A prospective, uncontrolled, nonrandomized, nonblind study enrolled 30 patients. They were cooperative and hemodynamically stable, aged over 18 years, and presented with acute respiratory distress as defined by predetermined criteria. They were connected to a BiPAP machine through a face mask, using an initial pressure of 8/3 cm H(2)O, which was gradually raised to 12/7 cm H(2)O inspiratory positive airway pressure/expiratory positive airway pressure. Standard drugs, inhalation and oxygen therapies were administered as needed. The BiPAP was disconnected either upon relief of respiratory distress or on deterioration of the patient's condition. RESULTS: Of the 30 patients in the study, 19 had cardiogenic pulmonary edema, four had acute asthma, three had exacerbation of COPD, three had pneumonia and one had malignant pleural effusion. BiPAP was instituted subsequent to failure of standard therapies. Twenty-six patients were classified as responders to the BiPAP ventilation and four as nonresponders (three patients were intubated after 1 hour and one patient 24 hours, post BiPAP). The total length of stay (LOS) in the ED was 3-5 hours and the mean LOS in hospital was 4.1 +/- 1.5 days, versus 6.5 +/- 1.2 days in LOS reports of similar patients in the same hospital during 1999, who did not undergo BiPAP ventilation. No other complications were observed. CONCLUSIONS: We found BiPAP ventilation simple, safe, effective and well tolerated by patients in respiratory distress. The rate of endotracheal intubation after successful BiPAP ventilation was low. In carefully selected patients with respiratory distress, BiPAP ventilation may successfully replace endotracheal intubation.

Prior peripheral arterial disease and cerebrovascular disease are independent predictors of adverse outcome in patients with acute coronary syndromes: are we doing enough? Results from the Orbofiban in Patients with Unstable Coronary Syndromes-Thrombolysis In Myocardial Infarction (OPUS-TIMI) 16 study.
BACKGROUND: Cerebrovascular accidents (CVAs), transient ischemic attacks (TIAs), and peripheral arterial disease (PAD) frequently coexist with coronary artery disease (CAD) and were previously reported to adversely affect the prognosis of patients with chronic CAD. METHODS: We examined the effect of prior CVA/TIA or PAD (extra-cardiac vascular disease [EVD]) on the outcome of 10,281 patients with acute coronary syndromes enrolled in the Orbofiban in Patients with Unstable Coronary Syndromes-Thrombolysis in Myocardial Infarction (OPUS-TIMI) 16 trial of the oral glycoprotein IIb/IIIa antagonist orbofiban plus aspirin versus aspirin alone. We evaluated mortality, recurrent cardiac events, and stroke and used multivariate analysis to control for differences in baseline characteristics. RESULTS: Patients with EVD were older, had more coronary risk factors, had a history of CAD, and received more intensive medical treatment at baseline. The acute event in these patients was more often unstable angina pectoris and less commonly Q-wave myocardial infarction. With coronary angiography, patients with prior EVD more often had multivessel disease. During the 10 months of follow-up, the presence of EVD was predictive of an increased hazard of death, reinfarction, recurrent ischemia, stroke, and a composite of these events. Despite the increased severity of the CAD and increased risk of events, patients with EVD were treated less frequently with beta-blockers and more frequently with calcium blockers. Despite patients with EVD having a 45% higher incidence of hypercholesterolemia, lipid-lowering agents were prescribed in a similar percentage of patients as patients without EVD. CONCLUSION: In patients with acute coronary syndromes, the presence of prior CVA, TIA, or PAD is associated with more extensive CAD and worse outcome. These patients appear to receive less aggressive treatment, which may explain, at least in part, their worse outcome.

Cardiovascular nursing in Israel.
Cardiovascular (CV) nursing as an entity in Israel dates back to 1952, when the nurses in Tel-Hashomer hospital took care of postoperative heart surgery patients. The first intensive cardiac care units (ICCUs) were established in 1971. In 1982, the first ICCU course was established in Tel-Hashomer hospital nursing school. Today, most of the nursing staff in Israels ICCUs are graduates of ICCU courses. The nurses professional society, the Society for Nursing of Israel, was established in 1947. In 1989 the Society for Advancement of Cardiac Nursing in Israel (SACN) was established. The main goals of the society were: the exchange of CV nursing knowledge, CV nursing research, CV nursing education in nursing schools, education of nurses in other departments in the care of the cardiac patient, and CV nursing education in the community. The CV nurse takes a large role in the total care of the cardiac patient, which includes rehabilitation within the hospital and in the ambulatory setting and coordination of nursing in national and international multicenter clinical trials. In collaboration with the Ministry of Health Nursing Division, Israeli CV nurses participate in national and international projects to: develop and upgrade nursing education; train new CV nurses; develop, review, and revise nursing protocols and guidelines; and establish new, more advanced ICCUs in underdeveloped areas within Israel and around the world. Our vision for the future development of CV nursing in Israel includes coordination and management roles in the hospital setting, and the establishment and management of home-care programs.
