  • Although women are less likely to be admitted to coronary care units, they are treated equally to men and have better outcome : A prospective cohort study in patients with non ST-elevation acute coronary syndromes
  • 2009
  • Ingår i: Acute cardiac care. - : Informa Healthcare. - 1748-295X .- 1748-2941. ; 11:3, s. 173-180
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The aim of this study was to assess gender differences in admission level of care, management and outcome in patients with non ST-elevation acute coronary syndromes (NSTE-ACS), initially admitted to either coronary care units (CCU) or general wards. Method: Patients admitted to CCUs were routinely registered in the RIKS-HIA registry. In addition, patients admitted to general wards with suspected ACS were also identified and registered. Multivariable regression analysis was used to adjust for baseline differences between the genders. Results: We included 570 consecutive patients with a discharge diagnosis of NSTE-ACS. Women were less likely to be admitted to coronary care units (56% versus 69%, P=0.002), even after adjustment (odds ratio (OR), 0.65; 95% confidence interval (CI): 0.43-0.98). After adjustment for differences in baseline characteristics, women were treated similarly to men. We found no significant differences in crude short-, or long-term mortality between the genders. However, adjustment for background characteristics revealed lower one-year mortality in women (OR: 0.58; 95% CI: 0.34-0.99). Conclusion: In this study on patients with NSTE-ACS, women were less likely to be admitted to coronary care units. However, the overall treatment was as intensive for women as for men. Moreover, after adjustment, one-year mortality was lower in women.

  • Randomized comparison of early supplemental oxygen versus ambient air in patients with confirmed myocardial infarction : Sex-related outcomes from DETO2X-AMI
  • 2021
  • Ingår i: American Heart Journal. - : Mosby Inc.. - 0002-8703 .- 1097-6744. ; 237, s. 13-24
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The purpose of this study is to investigate the impact of oxygen therapy on cardiovascular outcomes in relation to sex in patients with confirmed myocardial infarction (MI).Methods: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction trial randomized 6,629 patients to oxygen at 6 L/min for 6-12 hours or ambient air. In the present subgroup analysis including 5,010 patients (1,388 women and 3,622 men) with confirmed MI, we report the effect of supplemental oxygen on the composite of all-cause death, rehospitalization with MI, or heart failure at long-term follow-up, stratified according to sex.Results: Event rate for the composite endpoint was 18.1% in women allocated to oxygen, compared to 21.4% in women allocated to ambient air (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.65-1.05). In men, the incidence was 13.6% in patients allocated to oxygen compared to 13.3% in patients allocated to ambient air (HR 1.03, 95% CI 0.86-1.23). No significant interaction in relation to sex was found (P=.16). Irrespective of allocated treatment, the composite endpoint occurred more often in women compared to men (19.7 vs 13.4%, HR 1.51; 95% CI, 1.30-1.75). After adjustment for age alone, there was no difference between the sexes (HR 1.06, 95% CI 0.91-1.24), which remained consistent after multivariate adjustment.Conclusion: Oxygen therapy in normoxemic MI patients did not significantly affect all-cause mortality or rehospitalization for MI or heart failure in women or men. The observed worse outcome in women was explained by differences in baseline characteristics, especially age

  • Differences in symptoms, first medical contact and pre-hospital delay times between patients with ST- and non-ST-elevation myocardial infarction
  • 2019
  • Ingår i: European Heart Journal. - : Sage Publications. - 2048-8726 .- 2048-8734. ; 8:3, s. 201-207
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: In ST-elevation myocardial infarction, time to reperfusion is crucial for the prognosis. Symptom presentation in myocardial infarction influences pre-hospital delay times but studies about differences in symptoms between patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction are sparse and inconclusive. The aim was to compare symptoms, first medical contact and pre-hospital delay times in patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction.Methods and results: This multicentre, observational study included 694 myocardial infarction patients from five hospitals. The patients filled in a questionnaire about their pre-hospital experiences within 24 h of hospital admittance. Chest pain was the most common symptom in ST-elevation myocardial infarction and non-ST-elevation myocardial infarction (88.7 vs 87.0%, p=0.56). Patients with cold sweat (odds ratio 3.61, 95% confidence interval 2.29–5.70), jaw pain (odds ratio 2.41, 95% confidence interval 1.04–5.58), and nausea (odds ratio 1.70, 95% confidence interval 1.01–2.87) were more likely to present with ST-elevation myocardial infarction, whereas the opposite was true for symptoms that come and go (odds ratio 0.58, 95% confidence interval 0.38-0.90) or anxiety (odds ratio 0.52, 95% confidence interval 0.29–0.92). Use of emergency medical services was higher among patients admitted with ST-elevation myocardial infarction. The pre-hospital delay time from symptom onset to first medical contact was significantly longer in non-ST-elevation myocardial infarction (2:05 h vs 1:10 h, p=0.001).Conclusion: Patients with ST-elevation myocardial infarction differed from those with non-ST-elevation myocardial infarction regarding symptom presentation, ambulance utilisation and pre-hospital delay times. This knowledge is important to be aware of for all healthcare personnel and the general public especially in order to recognise symptoms suggestive of ST-elevation myocardial infarction and when to decide if there is a need for an ambulance.

  • Differences in symptoms in relation to myocardial infarction.
  • 2016
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Background: In myocardial infarction (MI) rapid diagnosis and treatment is crucial for the prognosis. Previous research has found that symptom presentation influence pre hospital delay times but studies about differences in MI symptoms between patients with ST-elevation myocardial infarction (STEMI) and non ST-elevation myocardial infarction (NSTEMI) are sparse and inconclusive. To enhance the understanding of symptom presentation in regard to MI type, we aimed to describe symptoms in relation to MI type and to find predictors of STEMI versus NSTEMI in patients with MI.Methods: Patients with MI (n=694) from the SymTime study were included. SymTime was a multicentre cross-sectional study of symptoms and actions in the prehospital phase of MI and data were collected using a previously validated questionnaire administered to MI patients within 24 h of admission to hospital.Results: Patients with STEMI were younger, more often men and smokers. Patients with NSTEMI were more likely to have a history of hypertension, MI and stroke. Chest pain was the most common symptom in both groups. Pain, discomfort, or pressure located in the jaw or teeth, vertigo/pre-syncope, cold sweat and nausea/vomiting were significantly more frequent in patients with STEMI (Table 1). In a multivariate logistic regression model patients with STEMI were more likely to present with cold sweat (OR 4.13, 95% CI 2.71–6.29) jaw pain (OR 2.14, 95% CI 1.02–4.50), and nausea (OR 2.01, 95% CI 1.20–3.33), and less likely to have a history of stroke (OR 0.35, 95% CI 0.15–0.84), fluctuating symptoms (OR 0.54, 95% CI 0.36–0.83) and anxiety (OR 0.54, 95% CI 0.32–0.92) compared to patients with NSTEMI.Conclusion: Patients with STEMI differed significantly from those with NSTEMI regarding symptom presentation. This knowledge is important for health care personnel to recognize symptoms alarming for STEMI when evaluating patients with MI symptoms.

  • Acute coronary syndrome : bleeding, platelets and gender
  • 2019
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • BACKGROUNDBleeding complications increase mortality in patients with acute coronary syndrome (ACS). Potential gender difference in bleeding regarding prevalence, location, severity and prognostic impact is still controversial and not well investigated. In regard to this aspect the relevance of triple antithrombotic therapy (TAT) is questioned. There is an ongoing debate on the clinical implications of TAT and furthermore assumed that bleeding complications, except impact on outcome, also are associated with great influence on health economy.The main focus of this thesis was to further investigate the incidence and impact of bleeding complications in patients treated for ACS, with special reference to gender disparities, TAT and health economics. The thesis will highlight the importance of improved bleeding prevention strategies for both men and women.METHODPaper I, II and IIIObservational studies from the SWEDEHEART register.In paper I we investigated patients hospitalised with myocardial infarction (MI) during 2006–2008. Outcomes were in-hospital bleedings, in-hospital mortality and one-year mortality in hospital survivors.In paper II, all patients with MI, in the County of Östergötland, Sweden during 2010 were included and followed for one year. The patients' medical records were evaluated, in relation to short and long-term bleeding complications, bleeding location, withdrawal of platelet inhibiting drugs and nonfatal MI and death.Paper III included all patients discharged with (TAT) in the County of Östergötland 2009-2015. Information about bleeds and ischemic complications during one-year follow-up were retrieved from the medical records. Estimation of the health care costs associated with bleeding episodes were added to the evaluation.Paper IVPatients with MI, scheduled for coronary angiography were recruited. All patients received clopidogrel and aspirin. A subgroup of patients received GP IIb/IIIa-inhibitor. Outcomes were platelet aggregation assessed at several time points, using a Multiplate impedance aggregometer, measurement of P-selectin in plasma, evaluation of high residual platelet reactivity (HRPR) and low residual platelet reactivity (LRPR) respectively and incidence of bleeding complications. A comparison between women and men was performed.RESULTSPaper IA total number of 50.399 patients were included, 36.6% women. In-hospital bleedings were more common in women (1.9% vs. 3.1%, p<0.001) even after multivariable adjustment (OR 1.17, 95%, CI 1.01–1.37). The increased risk for women was found in STEMI (OR 1.46, 95% CI 1.10–1.94) and in those who underwent PCI (OR 1.80, 95% CI 1.45–2.24).In contrast the risk was lower in medically treated women (OR 0.79, 95% CI 0.62–1.00). After adjustment, in-hospital bleeding was associated with higher risk of oneyear mortality in men (OR 1.35, 95% CI 1.04–1.74), whereas this was not the case in women (OR 0.97, 95% CI 0.72–1.31).Paper IIIn total 850 consecutive patients were included. The total incidence of bleeding events was 24.4% (81 women and 126 men, p=ns). The incidence of all in hospital bleeding events was 13.2%, with no gender difference. Women had significantly more minor nonsurgery related bleeding events than men (5% vs 2.2%, p=0.02). During follow-up, 13.5% had a bleeding, with more non-surgery related bleeding events among women, 14.7% vs 9.7% (p=0.03). The most common bleeding localisation was the gastrointestinal tract, more in women than men (12.1% vs 7.6%, p=0.03). Women also had more access site bleeding complications (4% vs 1.7%, p=0.04), while men had more surgery related bleeding complications (6.4% vs 0.9%, p≤0.001). Increased mortality was found only in men with non-surgery related bleeding events (p=0.008).Paper IIIAmong 272 identified patients, 156 bleeds occurred post-discharge, of which 28.8% were of gastrointestinal origin. In total 54.4% had at least one bleed during or after the index event and 40.1% bled post-discharge of whom 28.7% experienced a TIMI major or minor bleeding. Women discontinued TAT prematurely more often than men (52.9 vs 36.1%, p=0.01) and bled more (48.6 vs. 37.1%, p=0.09). One-year mean health care costs were EUR 575 and EUR 5787 in non-bleeding and bleeding patients, respectively.Paper IVWe recruited 125 patients (37 women and 88 men). We observed significantly more inhospital bleeding events in women as compared to men (18.9% vs 6.8%, p=0.04). There were no differences in platelet aggregation using three different agonists, reflecting treatment of GPIIb/IIIa inhibitors, clopidogrel and aspirin, at four different time-points nor were there any differences in p-selectin in plasma 3 days after admission.CONCLUSIONThere is a remarkably high bleeding incidence among patients treated with DAPT and even more so if treated with TAT. Female gender is an independent risk factor of inhospital bleeding after myocardial infarction, this higher bleeding risk in women appears to be restricted to invasively treated patients and STEMI patients. Even if women had higher short- and long-term mortality, there was no difference between the genders among those who bled. After multivariable adjustment the prognostic impact of bleeding complications was higher in menWomen seem to experience more minor/minimal bleeding complications than men, predominantly GI bleeding events and access site bleeding events, with no apparent impact on outcome.In contrast men with non-surgery related bleeding complications had higher mortality. There is a lack of differences between the genders concerning platelet aggregation. Our results do not support gender disparities in platelet reactivity and excess dosing as a major explanation for increased bleeding risk in women. Improved bleeding prevention strategies are warranted for both men and women.

    • Introduction: The aim of the current study was to assess bleeding events, including severity, localisation and prognostic impact, in a real world population of men and women with myocardial infarction (MI). Methods and results: In total 850 consecutive patients were included during 2010 and followed for one year. Bleeding complications were identified by searching of each patients medical records and characterised according to the TIMI criteria. For this analysis, only the first event was calculated. The total incidence of bleeding events was 24.4% (81 women and 126 men, p=ns). The incidence of all inhospital bleeding events was 13.2%, with no sex difference. Women had significantly more minor non-surgery related bleeding events than men (5% vs 2.2%, p=0.02). During follow-up, 13.5% had a bleeding, with more non-surgery related bleeding events among women, 14.7% vs 9.7% (p=0.03). The most common bleeding localisation was the gastrointestinal tract, more in women than men (12.1% vs 7.6%, p=0.03). Women had also more access site bleeding complications (4% vs 1.7%, p=0.04), while men had more surgery related bleeding complications (6.4% vs 0.9%, p=0.001). Increased mortality was found only in men with non-surgery related bleeding events (p=0.008). Conclusions: Almost one in four patients experienced a bleeding complication through 12 months follow-up after a myocardial infarction. Women experienced more non-surgery related minor/minimal bleeding complications than men, predominantly GI bleeding events and access site bleeding events, with no apparent impact on outcome. In contrast men with non-surgery related bleeding complications had higher mortality. Improved bleeding prevention strategies are warranted for both men and women.
