(Stina Gr\u00f8nbech)<\/p><\/div>\n<p><!--more-->In fact, a heart attack can happen without a person realizing it. It is called a silent heart attack, due to what is medically referred to as <a target=\"_blank\" href=\"http:\/\/www.heart.org\/HEARTORG\/Conditions\/HeartAttack\/PreventionTreatmentofHeartAttack\/Silent-Ischemia-and-Ischemic-Heart-Disease_UCM_434092_Article.jsp#.WEsXyE2QzIU\" >silent ischemia<\/a> (lack of oxygen) to the heart muscle.<\/p>\n<p>\u201cIt is unknown why some people experience heart attacks without symptoms. One possible explanation for the absence of chest pain is high pain tolerance. To our knowledge, no previous study has examined the relationship between pain sensitivity and recognition of heart attacks,\u201d said Andrea Ohrn, M.D., study lead author and Ph.D. Fellow at University of Troms\u00f8 in Norway.<\/p>\n<p>Researchers from Norway studied 4,849 adults who underwent a cold pressor test and electrocardiogram (ECG). The cold pressor test measured pain tolerance as participants placed their hand in ice-cold water at 3 degrees Celsius (about 37 degrees Fahrenheit) for as long as possible, up to two minutes.<\/p>\n<p>Researchers used ECG results and participant\u2019s hospital records to determine heart attack status (recognized, unrecognized, or no heart attack).<\/p>\n<p><strong>They found:<\/strong><\/p>\n<ul>\n<li>Overall, 8 percent of participants were classified as having a silent (unrecognized) heart attacks and 4.7 percent of participants as recognized heart attacks.<\/li>\n<li>Those with silent heart attack endured the cold pressor test significantly longer and were less likely to quit the test than those who recognized heart attack pain.<\/li>\n<li>Women had fewer heart attacks than men (7 percent vs. 19 percent), but a larger proportion of heart attacks were silent in women than in men (75 percent vs. 58 percent).<\/li>\n<li>More women aborted the cold pressor test compared to men (38 percent vs. 23 percent).<\/li>\n<li>However, the association between silent heart attack and lower pain tolerance was stronger in women than in men, and statistically significant in women only, but the sex difference was not statistically significant.<\/li>\n<\/ul>\n<p>\u201cAsking patients about their pain sensitivity might provide a clearer picture about their probability of presenting with heart specific symptoms in the case of a heart attack\u201d Ohrn said. \u201cAbsence of chest pain should not lower alertness of doctors towards ischemic heart disease.\u201d<\/p>\n<p>The larger difference in pain tolerance between unrecognized and recognized heart attack in women may be because women recognized with a heart attack might be those women most sensitive to pain, presenting with the most severe symptoms, Ohrn said.<\/p>\n<p>\u201cThe \u201csilent\u201d in a silent heart attack is the complicating factor \u2014 often, a silent heart attack is discovered a while after the acute incidence at the doctor\u2019s office or the hospital, by coincidence, if an ECG is recorded. In that case, it is very important to screen for cardiovascular risk factors, such as hypertension and cholesterol, and treat these rigorously according to existing guidelines. Also, it is important to think of a silent heart attack if a patient present with signs such as heavy breathing and swollen legs. These can be symptoms of heart failure because of a previous heart attack even though there is no record of one.\u201d<\/p>\n<p>The high prevalence and poor prognosis associated with silent heart attack, makes this a hidden public health issue that constitutes a larger proportion of women\u2019s heart disease.<\/p>\n<p>Co-authors are Christopher Sivert Nielsen Ph.D.; Henrik Schirmer, M.D., Ph.D.; Audun Stubhaug, M.D., Ph.D.; Tom Wilsgaard, Ph.D. and Haakon Lindekleiv, M.D., Ph.D. Author disclosures are on the manuscript.<\/p>\n<p>The Norwegian National Advisory Unit on Women\u2019s Health funded the study.<\/p>\n<p><strong>Additional Resources<\/strong><\/p>\n<ul>\n<li>View the manuscript <a href=\"http:\/\/jaha.ahajournals.org\/content\/5\/12\/e003846\" title=\"online\"  target=\"_blank\" rel=\"\">online<\/a>.<\/li>\n<li><a href=\"http:\/\/www.heart.org\/HEARTORG\/Conditions\/911-Warnings-Signs-of-a-Heart-Attack_UCM_305346_SubHomePage.jsp\" title=\"Heart Attack Warning Signs\"  target=\"_blank\" rel=\"\">Heart Attack Warning Signs<\/a><\/li>\n<li>Follow AHA\/ASA news on Twitter <a href=\"https:\/\/twitter.com\/heartnews\" title=\"@HeartNews\"  target=\"_blank\" rel=\"\">@HeartNews<\/a><\/li>\n<li>For updates and new science from JAHA, follow <a href=\"https:\/\/twitter.com\/jaha_aha\" title=\"@JAHA_AHA\"  target=\"_blank\" rel=\"\">@JAHA_AHA<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>American Heart Association Rapid Access Journal Report Dallas, TX &#8211; Heart attacks may go unrecognized among individuals with high pain tolerance, putting them at an increased risk for poor recoveries, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association\/American Stroke Association.
