BACKGROUND<\/strong>
\nThe obesity paradox refers to the phenomenon that obese patients seem to have a better outcome than normal weight patients in a variety of disease conditions. The aim of this study was to investigate the impact of Body Mass Index (BMI) on mortality in patients with ST-elevation myocardial infarction (STEMI) who underwent percutaneous coronary intervention (PCI).<\/p>\n

METHODS<\/strong>
\nBetween January 2005 and July 2012, the Swiss AMIS Plus registry enrolled 6,938 patients with acute STEMI who underwent PCI. These patients were stratified into 5 BMI groups according to the classification system of the World Health Organisation. The odds for in-hospital mortality according to BMI groups were analysed using logistic regression with normal weight patients as the reference.<\/p>\n

RESULTS<\/strong>
\nCrude in-hospital mortality rates showed a U-shaped distribution between BMI groups, with the lowest mortality in obese class I patients (2.0%) and the highest mortality in underweight patients (9.0%). The odds for in-hospital mortality were significantly lower for obese class I (OR 0.56; 95% CI 0.35-0.91) and significantly higher for underweight patients (OR 2.72; 95% CI 1.14-6.48) compared to the normal weight group and odds ratios showed a U-shaped distribution. After adjustment for covariates, the odds ratios maintained a U-shape distribution albeit the differences between BMI groups were no longer significant.<\/p>\n

CONCLUSION<\/strong>
\nThis study showed that the lower crude in-hospital mortality of obese class I patients can be partly explained by lower age and lower co-morbidity rates. However, further studies are needed to investigate favourable factors associated with class I obesity.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-31882","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"AMIS Plus Data Centre, Institute of Social and Preventive Medicine, University of Zurich, Zurich, Switzerland.\r\ndragana.radovanovic@uzh.ch","annee":"2014","mois":"8","numero":"144:","page":"w13986","auteurs":[{"ID":31877,"post_author":"0","post_date":"2018-12-03 23:51:19","post_date_gmt":"2018-12-03 22:51:19","post_content":"","post_title":"Fabienne Witassek","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"fabienne-witassek","to_ping":"","pinged":"","post_modified":"2018-12-03 23:51:19","post_modified_gmt":"2018-12-03 22:51:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/fabienne-witassek\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":31878,"post_author":"0","post_date":"2018-12-03 23:51:20","post_date_gmt":"2018-12-03 22:51:20","post_content":"","post_title":"Matthias Schwenkglenks","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"matthias-schwenkglenks","to_ping":"","pinged":"","post_modified":"2018-12-03 23:51:20","post_modified_gmt":"2018-12-03 22:51:20","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/matthias-schwenkglenks\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":31879,"post_author":"0","post_date":"2018-12-03 23:51:21","post_date_gmt":"2018-12-03 22:51:21","post_content":"","post_title":"Paul Erne","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"paul-erne","to_ping":"","pinged":"","post_modified":"2018-12-03 23:51:21","post_modified_gmt":"2018-12-03 22:51:21","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/paul-erne\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":31880,"post_author":"0","post_date":"2018-12-03 23:51:21","post_date_gmt":"2018-12-03 22:51:21","post_content":"","post_title":"Dragana Radovanovic","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"dragana-radovanovic","to_ping":"","pinged":"","post_modified":"2018-12-03 23:51:21","post_modified_gmt":"2018-12-03 22:51:21","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/dragana-radovanovic\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":31881,"post_author":"0","post_date":"2018-12-03 23:51:22","post_date_gmt":"2018-12-03 22:51:22","post_content":"","post_title":"Swiss Med Wkly","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"swiss-med-wkly","to_ping":"","pinged":"","post_modified":"2018-12-03 23:51:22","post_modified_gmt":"2018-12-03 22:51:22","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/swiss-med-wkly\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nImpact of Body Mass Index on mortality in Swiss hospital patients with ST-elevation myocardial infarction: does an obesity paradox exist?
