Comparative StudyChanges in demographic factors and mortality after out-of-hospital cardiac arrest in Sweden.
To describe changes between 1992 and 2003 in age, sex, factors at resuscitation and survival among patients suffering from out-of-hospital cardiac arrest in Sweden. ⋯ Among patients suffering from out-of-hospital cardiac arrest in Sweden some changes took place. The most important ones were a decrease in the proportion of patients found in ventricular fibrillation and an increase in the proportion of patients receiving bystander CPR. The proportion of patients admitted alive to hospital increased moderately, whereas the proportion of patients alive after 1 month remained unchanged.

Comparative StudyClinical impact of selective spasm provocation tests: comparisons between acetylcholine and ergonovine in 1508 examinations.
There are few reports regarding the concordance of coronary arterial response between acetylcholine (ACh) and ergonovine (ER) spasm provocation tests. ⋯ Thus, both selective ACh and ER tests were useful as spasm provocation tests.

Comparative StudyTroponin I as a specific marker of myocardial injury: from theory to clinical practice in the diagnosis of acute coronary syndrome.
To assess the diagnostic accuracy of troponin I (TnI) elevation in patients with acute coronary syndrome (ACS) in the emergency department (ED). ⋯ Abnormal values of TnI were detected in a variety of diseases not related to ACS. Even if troponin release indicates myocardial injury, it is not always synonymous with infarction or ischemia. A misinterpretation of TnI elevation may give rise to a diagnostic dilemma and cause unnecessary morbidity. An integration of biomarkers (TnI and CK-MB), ECG and WMSI will help identify false-positive ACS patients and avoid inappropriate admissions to CCU.

Comparative StudySpinal cord stimulation for refractory angina pectoris: a retrospective analysis of efficacy and cost-benefit.
Patients with refractory angina pectoris have severe symptoms despite optimal medication, but are not suitable for revascularisation. Spinal cord stimulation (SCS) has been used for treating refractory angina pectoris since 1985. The efficacy of SCS has been proven by randomised controlled trials and follow-up studies have shown that SCS is a safe treatment. The objective of the current study was to retrospectively analyse the clinical outcomes and cost-benefit of SCS in patients with refractory angina pectoris. ⋯ This retrospective study indicates that SCS treatment alleviates angina symptoms and improves quality of life. The treatment is also effective in preventing hospitalisations and saving costs in hospital care. A prospective study is warranted to confirm the current observations.

Comparative StudyReperfusion arrhythmias during coronary angioplasty for acute myocardial infarction predict ST-segment resolution.
Despite early recanalization of an occluded infarct-related artery, myocardial reperfusion may remain impaired due to microvascular injury. Reperfusion arrhythmias may indicate successful microvascular reperfusion. ⋯ Reperfusion arrhythmias following coronary angioplasty for AMI are a highly specific marker for ST resolution and may indicate successful microvascular reperfusion.
