Nicosia General Hospital cardiac arrest team: first year's practice and outcomes of in-hospital resuscitation.

INTRODUCTION: In 2007, Nicosia General Hospital implemented a resuscitation policy. 378 nurses and 120 doctors were successfully trained in advanced life support (ALS) in order to staff cardiac arrest teams. The aim of this study was to assess the frequency of cardiac arrest and resuscitation outcomes in Nicosia General Hospital and assess any associations between the survival rate and the patient's characteristics. We also aimed to evaluate the effectiveness of in-hospital resuscitation in order to detect ways of improvement. METHODS: We prospectively analyzed the data on all cardiac arrest calls in Nicosia General Hospital between January and December 2007. Data were collected using the Utstein style. RESULTS: The cardiac arrest team (CAT) was called 83 times, of which 10 were false alarms. Cardiac arrest was identified in 69 calls, while 4 calls were respiratory arrests. The patients' mean age was 70.8 years (95% CI: 66.6-75.1). In 86% the initial rhythm was asystole/pulseless electrical activity (PEA) and in 14% ventricular fibrillation/tachycardia (VF/VT). Return of spontaneous circulation was achieved in 52% of the cases. Survival to discharge was achieved in 17.8% of the patients with arrest and in 14.5% of cardiac arrests. Patients with an initial rhythm of asystole/PEA were discharged in 5% and patients with VF/VT in 70% of cases. About 36% of the patients less than 60 years old and 12% of the patients older than 60 were discharged. The CAT arrived within 1.6 minutes, first shock in VF/VT was delivered within 1.5 minutes and the first adrenaline dose in asystole/PEA was given within 2.7 minutes. CONCLUSIONS: It is more likely for our patients to survive to discharge if they are less than 60 years old, they are hospitalized in the cardiology department and the initial rhythm is VF/VT. Our outcomes are similar to survival rates in larger studies. However, points of improvement have been identified and interventions need to be made in order to improve documentation and outcomes of in-hospital arrests.

Beneficial effect of angiotensin II type 1 receptor blocker antihypertensive treatment on arterial stiffness: the role of smoking.

The purpose of the present study was to assess angiotensin receptor blocker (ARB) treatment on arterial stiffness in select hypertensive patients and define possible differences between smokers and nonsmokers. The authors evaluated 81 consecutive, nondiabetic patients (mean age, 52 years; 47 men) with uncomplicated essential hypertension with high plasma renin activity who were administered monotherapy with irbesartan, an ARB, at maximal dose. Patients were divided into smokers (n=24) and nonsmokers (n=57). Carotid-radial pulse wave velocity (PWVc-r), carotid-femoral pulse wave velocity (PWVc-f), and augmentation index (AIx) were measured before and 6 months after ARB antihypertensive treatment. All mean values of elastic effect indices were decreased after irbesartan monotherapy (AIx, from 26.3%to 21.2% [P<.01;] PWVc-f, from 7.7 m/s to 7.3 m/s [P<.05], and PWVc-r, from 8.9 m/s to 8.3 m/s [P<.001]). When comparing smokers vs nonsmokers, no difference was noted in AIx and PWVc-f change (P=not significant), while PWVc-r change was greater in smokers compared with nonsmokers (P<.05). Chronic ARB treatment may favorably affect arterial stiffness and wave reflections in hypertensive chronic smokers with elevated plasma renin levels.

Nocturnal blood pressure fall and metabolic syndrome score in hypertensive patients.

BACKGROUND: Data relating dipping status to metabolic syndrome (MS) scores are not available. The purpose of this study is to investigate any possible association of different dipping patterns to MS scores in untreated patients with essential hypertension. METHODS: The study included 6256 consecutive, treatment-naive patients with essential hypertension who attended our outpatient clinics. All underwent repeated office blood pressure measurements, 24-h ambulatory blood pressure monitoring, and full clinical and laboratory evaluation. The diagnosis of MS was made according to the Adult Treatment Panel III criteria and patients were classified into five groups: group I (hypertension), group II (hypertension+any one component), group III (hypertension+any two components), group IV (hypertension+any three components), and group V (all five components). Dipping pattern was defined as 'dippers' with nocturnal systolic blood pressure (NSBP) falling >or=10 but <20%, 'nondippers' with NSBP falling >or=0% but <10%, 'extreme dippers' with NSBP falling >or=20%, and 'reverse dippers' with NSBP increasing. RESULTS: Hypertensive patients with MS (n=2573) had higher clinical and ambulatory blood pressure values (P<0.001), whereas the dominant dipping pattern in the non-MS group was nondippers (47.6%), and in the MS group, extreme dippers (37.8%). Furthermore, a considerable decrease in the prevalence of dippers was noticed with the increasing number of MS components (21.1 vs. 19.2 vs. 14.5 vs. 8.4 vs. 7.2%, P<0.001). In contrast, a significant rise in the prevalence of reverse dippers was observed with the increasing number of MS components (7.4 vs. 10.1 vs. 14.9 vs. 20.4 vs. 31.2%, P<0.001). CONCLUSIONS: It seems that hypertensive patients have an increased prevalence of abnormal dipping patterns as the number of MS components rises.
