Similar outcome with an invasive strategy in men and women with Non ST-Elevation Acute Coronary Syndromes
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Gender differences in benefit from an early invasive strategy in patients with Non ST-elevation Acute Coronary Syndromes (NSTE ACS) have been debated and results are conflicting. Some studies have even indicated harm for women associated with a routine invasive strategy. Method: We included 46 455 patients ( 14 819 women (32%) and 31 636 men (68%)) from The Register of Information and Knowledge about Swedish Heart Intensive care Admissions (RIKS-HIA), with a diagnosis of either unstable angina pectoris or non-ST-elevation myocardial infarction. All patients were admitted to intensive coronary care units in Sweden, between 2000 and 2006, and followed for 1 year. Adjustment for baseline differences between the genders was made. Results: In the non-invasive strategy arm relative risk (RR) of death was (women vs. men) 1.02 (95% CI, 0.94-1.11) and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders with propensity score and discharge medication there was a trend towards lower mortality among women, RR 0.90 (95% CI, 0.82-0.99) in the early non-invasive group but still no difference in the early invasive cohort RR 0.90 (95% CI, 0.76-1.06). Results were similar with the combined end-point death/MI. The risk reduction with an invasive strategy was similar in women (RR 0.46 (95% CI 0.38-0.55)) and men (RR 0.45 (95% CI 0.40-0.52). Conclusion: In this large cohort of patients with NSTE ACS, reflecting real life management, women and men had similar outcome and similar benefit with an early invasive strategy.

- Background: Acute myocardial infarction (MI) is a leading cause for morbidity and mortality in Sweden. We aimed to compare patients with an acute MI included in the Register of information and knowledge about Swedish heart intensive care admissions (RIKS-HIA, now included in the register Swedeheart) and in the Swedish statistics of acute myocardial infarctions (S-AMI). Methods: Population based register study including RIKS-HIA, S-AMI, the National patient register and the Cause of death register. Odds ratios were determined by logistic regression analysis. Results: From 2001 to 2007, 114,311 cases in RIKS-HIA and 198,693 cases in S-AMI were included with a discharge diagnosis of an acute MI. Linkage was possible for 110,958 cases. These cases were younger, more often males, had fewer concomitant diseases and were more often treated with invasive coronary artery procedures than patients included in S-AMI only. There were substantial regional differences in proportions of patients reported to RIKS-HIA. Conclusions: Approximately half of all patients with an acute MI were included in RIKS-HIA. They represented a relatively more healthy population than patients included in S-AMI only. S-AMI covered almost all patients with an acute MI but had limited information about the patients. Used in combination, these two registers can give better prerequisites for improved quality of care of all patients with acute coronary syndromes.

- BACKGROUND: The extent and the severity of acute myocardial infarction (MI) is decreasing. Out-of-hospital medical management before the hospital admission could alter clinical presentation in acute MI. We used a large national patient register to investigate the relation between previous medication use (aspirin, beta-blockers, angiotensin-converting enzyme [ACE] inhibitors, and statins) and the risk of presenting with ST-segment elevation MI (STEMI) or non-STEMI. METHODS: We included 103 459 consecutive patients from the Swedish Register of Information and Knowledge About Swedish Heart Intensive Care Admissions (RIKS-HIA) admitted between January 1, 1996, and December 31, 2006, with a first acute MI. RESULTS: The patients with STEMI (43.5% of the total) were younger, had less prior cardiovascular disease, and used fewer medications before hospitalization. Of the STEMI patients, 61.4% had used no medication vs 45.9% of the patients with non-STEMI. After multiple adjustments, use of aspirin, beta-blockers, ACE inhibitors, and statins before hospitalization were all associated with substantially lower odds of presenting with STEMI. Furthermore, the risk decreased with the number of previous medications, and the use of 3 or more medications was associated with a multiply adjusted odds ratio of presenting with STEMI of 0.48 (99% confidence interval, 0.44-0.52) compared with no medications at admission. CONCLUSIONS: Use of aspirin, beta-blockers, ACE inhibitors, or statins before hospital admission in patients with a first acute MI is associated with substantially less risk of presenting with STEMI. The risk decreases with the increasing number of these medications used before acute MI, underlining the benefit of preventive medication in high-risk patients.
