- Objective-: CXCL16 and osteoprotegerin (OPG) both predict mortality in acute coronary syndromes. We hypothesized that a combination of CXCL16 and OPG concentrations would add prognostic information to the Global Registry of Acute Coronary Events (GRACE) score in patients hospitalized for acute coronary syndromes. Methods and Results-: We assessed the associations between circulating OPG and soluble CXCL16 levels, obtained within 24 hours of admission (day 1) and after 3 months, and mortality, heart failure and reinfarction in 1322 patients admitted with acute coronary syndromes. After adjustment for the GRACE score, medication, diabetes mellitus and sex, the combination of high values (fourth quartile) for OPG and CXCL16 at baseline was associated with increased short-term (3 months) cardiovascular mortality (hazard ratio, 3.28; 95% CI, 1.84-5.82; P<0.0001). The combined high values were also significantly associated with the long-term (median 91 months) prognosis after adjustment, with hazard ratios 2.18 for cardiovascular mortality (95% CI, 1.62-2.92; P<0.0001), and 2.22 for heart failure (95% CI, 1.67-2.96; P<0.0001). These long-term associations remained significant after further adjustment for left ventricular ejection fraction, C-reactive protein, and pro B-type natriuretic peptide. For 635 patients with blood samples within 24 hours and at 3 months, the combination of high CXCL16 and OPG values (fourth quartile) in the early or stable phase was of a similar order associated with mortality and morbidity beyond 3 months. Conclusion-: Circulating CXCL16 and OPG are independent predictors of long-term mortality and heart failure development in acute coronary syndromes patients, even after extensive adjustments. Their combination gives more information than either marker alone.

- During a 21-month period, the prognosis in all patients admitted to a hospital ward from the emergency room with suspected acute myocardial infarction (AMI) was prospectively recorded and related to the time between onset of symptoms and arrival in hospital. They were classified as early arrivers (less than or equal to 2 h), intermediate arrivers (2-8 h) and late arrivers (greater than 8 h). Among patients developing a confirmed AMI (n = 909) the 1-year mortality rate was 26.0% in early arrivers, 28.1% in intermediate arrivers and 32.6% in late arrivers. The corresponding figures for patients in whom AMI was ruled out (n = 2,035) were 15.2, 15.1 and 17.6%, respectively. In AMI patients, various morbidity aspects during hospitalization and 1 year of follow-up appeared mainly independent of delay time, whereas among those in whom AMI was ruled out congestive heart failure during hospitalization was most common in early arrivers. We conclude that patients with suspected AMI who do not arrive early in hospital have a high 1-year mortality rate regardless of whether they develop AMI or not. Whether their prognosis can be improved by shortening of delay time remains to be clarified.

- AIM: To describe patient characteristics, hospital investigations and interventions and early mortality among patients being hospitalized after out-of-hospital cardiac arrest in two hospitals. SETTING: Municipality of Göteborg, Sweden. PATIENTS: All patients suffering an out-of-hospital cardiac arrest who were successfully resuscitated and admitted to hospital between 1 October 1980 and 31 December 1996. All patients were resuscitated by the same Emergency Medical Service and admitted alive to one of the two city hospitals in Göteborg. RESULTS: Of 579 patients admitted to Sahlgrenska Hospital, 253 (44%) were discharged alive and of 459 patients admitted to Ostra Hospital, 152 (33%) were discharged alive (P < 0.001). More patients in Sahlgrenska Hospital were still receiving cardiopulmonary resuscitation (CPR) treatment (P = 0.03), but patients in Ostra had a lower systolic blood pressure and higher heart rate on admission. A larger percentage of patients admitted to Sahlgrenska Hospital underwent coronary angiography (P < 0.001), electrophysiological testing (P < 0.001), Holter recording (P < 0.001), echocardiography (P = 0.004), percutaneous transluminal coronary angioplasty (PTCA, P = 0.009), implantation of automatic implantable cardioverter defibrillator (AICD, P = 0.03) and exercise stress tests (P = 0.003). Inhabitants in the catchment area of Ostra Hospital had a less favourable socio-economic profile. CONCLUSION: Survival after out-of-hospital cardiac arrest may be affected by the course of hospital management. Other variables that might influence survival are socio-economic factors and cardiorespiratory status on admission to hospital. Further investigation is called for as more patients are being hospitalised alive after out-of-hospital cardiac arrest.

- OBJECTIVE: To describe the impact of ejection fraction on the prognosis during 2 years after coronary artery bypass grafting (CABG). PATIENTS: All patients in western Sweden who underwent CABG without concomitant valve surgery between June 1988 and June 1991. RESULTS: In all, 2121 patients were operated upon and information on ejection fraction was available for 1961 patients (92%). Of these patients, 178 (9%) had an ejection fraction < 40%, 517 (26%) an ejection fraction of 40-59% and 1266 (65%) an ejection fraction > or = 60%. In these groups the mortalities during the first 30 days after CABG were 5.1, 4.3 and 2.2%, respectively (P < 0.01). The corresponding values for mortalities between 30 days and 2 years were 7.7, 4.3 and 3.3%, respectively (P < 0.01). Patients with a lower ejection fraction were more frequently men and more frequently had a history of cardiovascular disease. In multivariate analysis the preoperative ejection fraction was an independent predictor for total 2-year mortality. Patients with a low ejection fraction died more frequently in association with ventricular fibrillation. Morbidity was, with the exception of that for rehospitalization due to heart failure and infection, not associated significantly with the preoperative ejection fraction. CONCLUSION: During the 2 years after CABG a low preoperative ejection fraction was associated with a higher mortality, but the association with morbidity was more complex.

- AIM: To describe the limitation of physical activity, the cause of limitation of physical activity and symptoms of dyspnea and chest pain before and 2 years after coronary artery bypass grafting (CABG) in relation to a history of hypertension. METHODS: All patients from western Sweden who underwent CABG between 1988 and 1991 were approached with a questionnaire--prior to, 3 months and 2 years after CABG--evaluating the issues raised above. RESULTS: Of 2121 patients, 37% had a history of hypertension. By 3 months after CABG, physical activity tolerance had improved markedly and in a similar way for both hypertensive (p<0.001) and non-hypertensive patients (p<0.001); this level was sustained for 2 years. Absence of dyspnea increased markedly and similarly among both hypertensive and non-hypertensive patients (p < 0.001) after CABG. The presence of chest pain decreased markedly and similarly among hypertensive (p<0.001) and non-hypertensive patients (p<0.001), both 3 months and 2 years after compared to prior to the operation. CONCLUSION: There was a marked improvement in terms of physical activity and cardiovascular symptoms 3 months and 2 years after CABG as compared with the situation prior to the operation. A previous history of hypertension did not seem to affect these results.

- AIM: To describe mortality and morbidity early and late after combined valve surgery and coronary artery bypass grafting (CABG) as compared with CABG alone. PATIENTS and METHODS: All patients from western Sweden in whom CABG in combination with valve surgery or CABG alone was carried out in 1988-1991. RESULTS: Among 2116 patients who underwent CABG, 35 (2%) had this combined with mitral valve surgery and 134 (6%) had this combined with aortic valve surgery, whereas the remaining 92% underwent CABG alone. Patients who underwent combined valve surgery and CABG were older, included more women and had a higher prevalence of previous congestive heart failure and renal dysfunction but on the other hand a less severe coronary artery disease. Among patients who underwent mitral valve surgery in combination with CABG the mortality over the subsequent 5 years was 45%). The corresponding figure for patients who underwent aortic valve surgery in combination with CABG was 24%. Both were higher than for CABG alone (14%; P < 0.0001 and P = 0.003, respectively). In a stepwise multiple regression model mitral valve surgery in combination with CABG was found to be an independent significant predictor for death but aortic valve surgery in combination with CABG was not. Among patients who underwent mitral valve surgery in combination with CABG and were discharged alive from hospital 77% were rehospitalized during the 2 years following the operation as compared with 48% among patients who underwent aortic valve surgery in combination with CABG and 43% among patients with CABG alone. Multiple regression identified mitral valve surgery in combination with CABG as a significant independent predictor for rehospitalization but not aortic valve plus CABG. CONCLUSION: Among patients who either underwent CABG in combination with mitral valve surgery or aortic valve surgery or CABG alone, mitral valve surgery in combination with CABG was independently associated with death and rehospitalization, but the combination of aortic valve surgery and CABG was not.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To describe mortality and morbidity during a 2-year period after coronary artery bypass grafting (CABG) among diabetic and nondiabetic patients. RESEARCH DESIGN AND METHODS: All the patients in western Sweden in whom CABG was undertaken between June 1988 and June 1991 and in whom concomitant procedures were not performed were registered prospectively. The study was a prospective follow-up. RESULTS: Diabetic patients (n = 268) differed from nondiabetic patients (n = 1,859) in that more women were included, and the patients more frequently had a previous history of myocardial infarction (MI), hypertension, congestive heart failure, intermittent claudication, and obesity. Diabetic patients more frequently required reoperation and had a higher incidence of peri- and postoperative neurological complications. Mortality during the 30 days after CABG was 6.7% in diabetic patients versus 3.0% in nondiabetic patients (P < 0.01). Mortality between day 30 and 2 years was 7.8 and 3.6%, respectively (P < 0.01). During 2 years of follow-up, a history of diabetes appeared to be a significant independent predictor of death. Whereas the development of MI after discharge from the hospital did not significantly differ between the two groups; 6.3% of diabetic patients developed stroke versus 2.5% in nondiabetic patients (P < 0.001). CONCLUSIONS: Diabetic patients have a mortality rate during the 2-year period after CABG that is about twice that of nondiabetic patients during both the early and late phase after the operation.

- BACKGROUND: To describe limitation of physical activity, cause of limitation of physical activity and symptoms of dyspnea and chest pain in relation to age before and 2 years after coronary artery bypass grafting (CABG). METHODS: All patients from Western Sweden who underwent CABG without concomitant procedures during 3 years in 1989-1991 answered questionnaires before, and 2 years after the operation. Patients were divided into 3 age groups of equal size i.e. 32-59 years, 60-67 years and > or = 68 years. RESULTS: In total, 2121 patients participated in the evaluation. The overall 2 year mortality in the 3 age groups was 3.8%, 6.8% and 12.2% (p<0.001). Limitation of physical activity was significantly associated with age prior to surgery but not thereafter. Improvement in physical activity, following CABG, was significant in all age groups. The proportion of patients being free of dyspnea increased markedly regardless of age. The number of chest pain attacks was associated with age after CABG, i.e. fewer attacks in the elderly, but such an association was not found prior to surgery. Improvement in number of chest pain attacks was more marked in the elderly. CONCLUSIONS: Physical activity improved similarly in all age groups after CABG. Attacks of chest pain, although significantly reduced in all age groups, seemed more effectively reduced in the elderly.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To determine the clinical factors before, and in association with, coronary artery bypass grafting (CABG) that increase the risk of readmission to hospital in the first two years after surgery. PATIENTS: All patients in western Sweden who had CABG without simultaneous valve surgery between 1 June 1988 and 1 June 1991. METHODS: All patients who were readmitted to hospital were evaluated by postal inquiry and hospital records. RESULTS: A total of 2121 patients were operated on, of whom 2037 were discharged from hospital. Information regarding readmission was missing in four patients, leaving 2033 patients; 44% were readmitted to hospital. The most common reasons for readmission were angina pectoris and congestive heart failure. There were 12 independent significant predictors for readmission: clinical history (a previous history of either congestive heart failure or myocardial infarction, or CABG); acute operation; postoperative complications (time in intensive care unit greater than two days, neurological complications); clinical findings four to seven days after the operation (arrhythmia, systolic murmur equivalent to mitral regurgitation); medication four to seven days after the operation (antidiabetics, diuretics for heart failure, other antiarrhythmics (other than beta blockers, calcium antagonists, and digitalis), and lack of treatment with aspirin). CONCLUSION: 44% of patients were readmitted to hospital two years after CABG. The most common reasons for readmission were angina pectoris and congestive heart failure. Four clinical markers predicted readmission: clinical history; acute operation status; postoperative complications; and clinical findings and medication four to seven days after operation.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: There have been few studies of the outcome in elderly patients who have suffered in-hospital cardiac arrest (IHCA) and the association between cardiac arrest characteristics and survival.AIM: The aim of this large observational study was to investigate the survival and neurological outcome in the elderly after IHCA, and to identify which factors were associated with survival.METHODS: We investigated elderly IHCA patients (≥70years of age) who were registered in the Swedish Cardiopulmonary Resuscitation Registry 2007-2015. For descriptive purposes, the patients were grouped according to age (70-79, 80-89, and ≥90years). Predictors of 30-day survival were identified using multivariable analysis.RESULTS: Altogether, 11,396 patients were included in the study. Thirty-day survival was 28% for patients aged 70-79 years, 20% for patients aged 80-89 years, and 14% for patients aged ≥90years. Factors associated with higher survival were: patients with an initially shockable rhythm, IHCA at an ECG-monitored location, IHCA was witnessed, IHCA during daytime (8 a.m.-8 p.m.), and an etiology of arrhythmia. A lower survival was associated with a history of heart failure, respiratory insufficiency, renal dysfunction and with an etiology of acute pulmonary oedema. Patients over 90 years of age with VF/VT as initial rhythm had a 41% survival rate. We found a trend indicating a less aggressive care with increasing age during cardiac arrest (fewer intubations, and less use of adrenalin and anti-arrhythmic drugs) but there was no association between age and delay in starting cardiopulmonary resuscitation (CPR). In survivors, there was no significant association between age and a favourable neurological outcome (CPC score: 1-2) (92%, 93%, and 88% in the three age groups, respectively).CONCLUSIONS: Increasing age among the elderly is associated with a lower 30-day survival after IHCA. Less aggressive treatment and a worse risk profile might contribute to these findings. Relatively high survival rates among certain subgroups suggest that discussions about advanced directives should be individualized. Most survivors have good neurological outcome, even patients over 90 years of age.
