- OBJECTIVES: The objectives of this study were to examine the time course of the inflammatory response in acute coronary syndromes (ACS) and to assess the markers of inflammation and their relation to disease severity. METHODS: We prospectively studied 134 patients with ACS who survived for at least 30 months. The patients were divided into four groups: acute myocardial infarction (MI) with (n=54) or without (n=46) ST-segment elevation and unstable angina with (n=14) or without (n=20) increased risk. Plasma levels of C-reactive protein (CRP), interleukin-6 (IL-6), secretory phospholipase A(2) group IIA (sPLA(2)-IIA), and intercellular adhesion molecule-1 (ICAM-1) were measured on days 1 and 4 and after 3 and 30 months. RESULTS: The highest levels of CRP and sPLA(2)-IIA were seen on day 4 but for IL-6 on day 1. These three markers, but not ICAM-1, were significantly related to disease severity, CKMB, and ejection fraction. Patients in Killip class II-IV had higher levels than those in Killip class I. The individual acute-phase responses correlated with marker levels at 3 and 30 months. ICAM-1 correlated with the development of congestive heart failure. CONCLUSIONS: In ACS there seems to be an individual predisposition to inflammatory response. Plasma IL-6 is the first marker to rise, while sPLA(2)-IIA and CRP peak later. All three markers, especially CRP, may discriminate between MI and non-MI. ICAM-1 seems to reflect other aspects of the inflammatory processes than the other markers. The results emphasize the complexity of the inflammatory response in ACS and stress the need for further studies involving multiple markers.

- BACKGROUND: Plasma renin activity (PRA) has been related to all-cause mortality and cardiovascular events in patients with cardiovascular disease. However, data from patients with acute coronary syndromes (ACS) are sparse.METHODS: Determination of PRA was made in 550 patients with ACS, including a subgroup of 287 patients not on treatment with angiotensin converting enzyme inhibitors, angiotensin receptor blockers or diuretics, and without heart failure. We evaluated the relations between PRA and all-cause mortality after three years and long-term, and to cardiovascular events after median 8.7 years. Adjustments were made for variables that influenced the hazard ratio (HR) > 5% for the relation between PRA and outcome.RESULTS: Baseline PRA was associated with all-cause mortality during three-years (unadjusted HR 1.74 per 1 SD increase in logarithmically transformed PRA; 95% confidence interval (CI) 1.39-2.16, p < 0.0001) and long-term (HR 1.12, CI 1.00-1.25, p = 0.046). After adjustments, only the three-year association remained significant. In unadjusted analyses, PRA was associated with cardiovascular death, but not with nonfatal cardiovascular events. In the subgroup there was an inverse relation between PRA and long-term all-cause mortality.CONCLUSION: Higher PRA was a significant independent predictor of all-cause mortality after three years, but not at long-term follow-up and not significantly associated with cardiovascular incidence. The renin-angiotensin-system pathophysiology is of great interest, not least due to its association with the COVID-19 pandemic. Our findings indicate a need for further research on the prognostic/predictive aspects of the renin-angiotensin-system in ACS.

Treatment and outcome in acute myocardial infarction in a community in relation to gender
- 2008

Journal article (peer-reviewed)abstract
- AIM: To describe treatment and outcome in all patients in a community with acute myocardial infarction (AMI) in relation to gender. METHODS: All patients discharged from hospital between 2001 and 2002 in Goteborg, Sweden, with a diagnosis of AMI underwent a survey to find possible gender differences. All p-values are age adjusted. RESULTS: Among 1423 admissions, women comprised 41% and were older than men (mean 79 versus mean 72 years). Women were admitted to a coronary care unit less frequently than men (49% versus 67%; p=0.005). Women underwent coronary angiography less frequently (21% versus 40%; p=0.02). Percutaneous coronary intervention (PCI) was performed in 10% of the women and 18% of the men (p=0.36). Coronary artery bypass grafting (CABG) was performed in 2% of the women and in 9% of the men (p<0.0001). Female gender was associated with a lower risk of reinfarction during first year after hospital discharge (12% versus 16%; p=0.003). The cumulative three-year mortality was 49% in women and 41% in men. However, when adjusting for age, admittance to CCU, coronary angiography and coronary revascularisation, risk of death during 3 years was lower in women than men (odds ratio 0.72; 95% confidence interval 0.60-0.85; p=0.0001). CONCLUSION: In the community of Goteborg women (mean age 79 years) with AMI are prioritised differently than men (mean age 72 years), prior to admission to a CCU. This results in a less invasive strategy in women, particularly with regard to CABG. When adjusting for difference in age, admittance to CCU and coronary revascularisation female gender was associated with a low risk of death during the subsequent 3 years.

Journal article (peer-reviewed)abstract
- BACKGROUND: There is limited information on long-term outcome in patients surviving the acute phase of an acute coronary syndrome (ACS). As yet, the effects of the type of syndrome and sex on mortality and morbidity in the long run have not been well described. METHODS: We studied 1618 patients <80 years old with ACS and alive 30 days after hospitalization in a coronary care unit. The patients were followed for 5 years. They were divided into 4 groups according to the type of ACS (ST-segment elevation myocardial infarction [STEMI], non-STEMI, unstable angina pectoris high risk, and unstable angina pectoris low risk). RESULTS: There was no significant sex difference in unadjusted 5-year mortality (P = .20). After adjustment for age, the hazard ratio with the corresponding 95% CI for a higher late 5-year mortality in women in relation to men was 0.89 (0.70-1.13, P = .34). Women were hospitalized for heart failure significantly more frequently during follow-up, a significance that disappeared after adjustment for age. Non-STEMI was associated with a significantly higher long-term mortality than STEMI, before but not after adjustment for covariates (hazard ratio [95% CI] 1.02 [0.75-1.37], P = .92). Of these, age, ST depression on admission, and early revascularization with percutaneous coronary intervention appeared to be of particular importance. Non-STEMI had a significantly higher rate of acute/subacute revascularization during follow-up, even after adjustment for age. CONCLUSIONS: Before, but not after, adjustment for covariates, a diagnosis of non-STEMI was associated with a poorer prognosis than other types of ACS. Small sex differences in long-term outcome in survivors of ACS were found.

Journal article (peer-reviewed)abstract
- BACKGROUND: Morbidity after acute coronary syndromes includes both physical and mental disorders affecting quality of life. The aim of this investigation was to study quality of life at a 3-month follow-up in patients with acute coronary syndrome, with the main objective of exploring whether unstable angina pectoris and myocardial infarction (MI) patients differ in this respect. METHODS: This investigation was part of a prospective risk stratification study of consecutive patients with acute coronary syndrome of whom 814 below the age of 75 years (278 diagnosed with unstable angina pectoris and 536 with myocardial infarction) accepted an invitation to a follow-up visit 3 months after discharge. At follow-up, the patients completed the Cardiac Health Profile, a disease-specific quality of life questionnaire, designed to evaluate perceived cognitive, emotional, social and physical function. RESULTS: Quality of life was mainly influenced by patient characteristics and previous history. The Cardiac Health Profile scores in unstable angina pectoris patients were significantly higher (i.e. poorer quality of life) than myocardial infarction patients at the 3-month visit (34, 22, 50; median, 25th, 75th percentile and 30, 19, 44; median, 25th, 75th percentile, respectively, P=0.006). The adjusted odds ratio for a poorer quality of life in unstable angina pectoris patients in relation to myocardial infarction patients was 1.39 (95% confidence interval 1.03, 1.87; P=0.03). The highest Cardiac Health Profile scores were seen in the unstable angina pectoris patients without electrocardiogram signs of ongoing ischemia and/or elevated markers of myocardial necrosis. CONCLUSION: Patients with unstable angina pectoris, especially of the low-risk type, and therefore treated accordingly, are more likely to experience poorer quality of life following an acute hospitalization than patients with other types of acute coronary syndrome. Once myocardial infarction or high-risk unstable angina pectoris has been ruled out, these patients still require a careful and systematic follow-up.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To study sex-based differences in the clinical presentation in relation to age and type of acute coronary syndrome (ACS) in patients under 80 years of age. METHODS: The study includes 1,744 consecutive patients with the full spectrum of ACS (ST elevation myocardial infarction (MI), non-ST elevation MI, and unstable angina of high- and low-risk types) admitted to the coronary care unit in a university hospital. RESULTS: The women were older than the men and were as likely to present with ST elevation MI. They had lower rates of prior MI and prior coronary artery bypass surgery than men but similar rates of percutaneous coronary interventions. Further, women were less likely to have a short delay before admission to hospital and they were attended to less rapidly in the emergency department. The prevalence of risk factors, prior cardiovascular disease and ongoing treatment with cardiovascular drugs were strongly associated with less severe type of ACS with no significant sex interaction. Presentation with non-ST elevation MI was significantly associated with older age while the opposite was true for unstable low-risk angina. ECG signs of acute ischemia were not associated with age. Significant interactions between age and sex were observed for the prevalence of treatment with diuretics as well as hypotension at presentation, both more prevalent among women than men below 65 years of age. CONCLUSIONS: Women are struck by ACS at a higher age than men, are less likely to present early for hospital care, and at younger age women are more likely to present with hypotension. There is a striking difference in risk factors and previous history depending on type of ACS in both sexes.

Journal article (peer-reviewed)abstract
- OBJECTIVE: To study differences in treatment and early morbidity and mortality in relation to gender, type of acute coronary syndrome (ACS) and age in patients under 80 years of age. METHODS: We studied 1744 consecutive patients with ACS with assumed decreasing order of severity [ST-elevation myocardial infarction (MI), non-ST-elevation MI and unstable angina of high- and low-risk types] admitted to the coronary care unit at Sahlgrenska University Hospital. RESULTS: The use of thrombolysis and percutaneous coronary interventions (PCI) did not differ significantly between gender groups and women did not suffer from more severe complications than men. Treatment with beta-blockers, ACE inhibitors and aspirin was used on a similar scale among women and men. In-hospital complications and use of intravenous drugs were strongly associated with severity of disease in a similar way among women and men. The mortality rates at 30 days were 12.4% and 7.4% in MI with and without ST-segment elevation, but only 1.3% and 1.0% in unstable angina of high- and low-risk types. The use of primary PCI decreased with age, as did coronary angiography and PCI in the subacute phase, irrespective of gender. CONCLUSION: Among patients <80 years with ACS admitted to a coronary care unit, the suspicion that women are treated less aggressively than men could not be verified. Nor did women suffer from more complications or have a significantly higher 30-day mortality than men. Elderly patients were significantly less likely to undergo invasive procedures than those of a younger age, irrespective of gender.

- BACKGROUND: Acute phase hyperglycaemia has been associated with increased mortality in patients with acute coronary syndrome. We investigated whether the predictive value of admission hyperglycaemia for mortality differs between diabetics and non-diabetics with acute coronary syndrome. METHODS: Patients with acute coronary syndrome (n=1957) were followed up prospectively for 45 months. Patients were stratified into quartile groups defined by admission plasma glucose and hyperglycaemia was defined as plasma glucose of >9.4 mmol/l, which was the cut-off value for the 4th quartile. The relationship between admission hyperglycaemia and short-term (< or =30 day) and late (>30 day) mortality was analysed. RESULTS: Of 1957 patients, 22% had a history of diabetes. Among patients without diabetes, those with hyperglycaemia had both a higher 30-day mortality rate (20.2% vs. 3.5%, p<0.0001) and late mortality rate (19.1% vs. 11.7%, p=0.007). Hyperglycaemic patients with diabetes had a higher late mortality rate than diabetic patients with plasma glucose of < or =9.4 mmol/l (29.3% vs. 14.9%, p=0.001). Of patients with hyperglycaemia at admission, those without diabetes had a higher 30-day mortality rate compared with those with diabetes (p=0.002). CONCLUSION: Admission hyperglycaemia is a strong risk factor for mortality in patients with acute coronary syndrome and may be even stronger than a previous history of diabetes. Hyperglycaemic patients without recognised diabetes have a higher short-term mortality risk than hyperglycaemic patients with known diabetes.

Journal article (peer-reviewed)abstract
- Abstract BACKGROUND: The gender perspectives of the triage of acute coronary syndromes (ACS) in a community are insufficiently explored. METHODS: Patients (n=3224) with symptoms of ACS, in whom ECG was sent by the ambulance crew to a coronary care unit (CCU)/ cath lab, were investigated in the municipality of Göteborg in 2004-2007. Background, triage priority, investigations and treatment were analysed (p-values age adjusted) in relation to gender. Data were compared with three published studies (1995-2002: Surveys 1-3). RESULTS: Women were directly admitted to the CCU significantly less frequently than men (23 versus 35%, p<0.0001). Adjusted for ECG findings, age, symptoms and medical history, odds ratio and 95% confidence limits (for direct admission; men versus women) were 0.61; 0.46-0.82. SURVEY 1: Patients with ACS, aged <80, in CCU at a university hospital (n=1744). Only minor differences between women and men, with regard to investigations and treatment, were found. SURVEY 2: Patients discharged from hospital (dead or alive) with AMI, regardless of type of ward (n=1423). Fewer women than men were admitted to CCU and fewer women underwent coronary angiography (21% versus 40%; p=0.02) and coronary revascularisation (12% versus 27%; p=0.004). SURVEY 3: Patients with symptoms of AMI (n=930) and patients with a confirmed AMI (n=130) from a pre-hospital perspective. Women tended to be given lower priority than men both by the ambulance dispatchers and by the ambulance crew. CONCLUSION: In our practice setting, men are given priority over women in admission to CCU, but no gender differences are seen thereafter.

Journal article (peer-reviewed)abstract
- Gender differences in outcome and its predictors in patients with acute coronary syndrome (ACS) continue to be debated.To assess long-term mortality and explore its association with the baseline variables in women and men.We followed 2,176 consecutive patients (665 women and 1,511 men) with ACS admitted to a single hospital and still alive after 30 days for a median of 16 years 8 months.At the end of the follow-up, 415 (62.4%) women and 849 (56.2%) men had died (unadjusted hazard ratio [HR] for women/men 1.18 (95% confidence interval [CI], 1.05-1.33, p =0.005). After adjustment for age, the HR was reversed to 0.88 (95% CI, 0.78-1.00, p =0.04). Additional adjustment for potential confounders yielded a HR of 0.86 (95% CI, 0.76-0.98, p = 0.02). Using multivariable Cox regression, previous heart failure, previous or new-onset atrial fibrillation, and psychotropic drugs at discharge were significantly associated with increased long-term mortality in men only. Known hypertension, elevated creatinine, and inhospital Killip class >1/cardiogenic shock were significantly associated with mortality only in women. For late mortality, hypertension and inhospital Killip class >1/cardiogenic shock interacted significantly with gender.For patients with ACS surviving the first 30 days, late mortality was lower in women than in men after adjusting for age. The effects of several baseline characteristics on late outcome differed between women and men. Gender-specific strategies for long-term follow-up of ACS patients should be considered.
