Low-grade systolic murmurs in healthy middle-aged individuals: innocent or clinically significant? A 35-year follow-up study of 2014 Norwegian men. J Intern Med 2012; 271: 581-588.Objective. To determine whether a low-grade systolic murmur, found at heart auscultation, in middle-aged healthy men influences the long-term risk of aortic valve replacement (AVR) and death from cardiovascular disease (CVD). During 1972During -1975During , 2014 apparently healthy men aged 40-59 years underwent an examination programme including case history, clinical examination, blood tests and a symptom-limited exercise ECG test. Heart auscultation was performed under standardized conditions, and murmurs were graded on a scale from I to VI. No men were found to have grade V ⁄ VI murmurs. Participants were followed for up to 35 years.
Setting and subjects.Results. A total of 1541 men had no systolic murmur; 441 had low-grade murmurs (grade I ⁄ II) and 32 had moderate-grade murmurs (grade III ⁄ IV). Men with lowgrade murmurs had a 4.7-fold [95% confidence interval (CI) 2.1-11.1] increased age-adjusted risk of AVR, but no increase in risk of CVD death. Men with moderategrade murmurs had an 89.3-fold (95% CI 39.2-211.2) age-adjusted risk of AVR and a 1.5-fold (95% CI 0.8-2.5) age-adjusted increased risk of CVD death.Conclusions. Low-grade systolic murmur was detected at heart auscultation in 21.9% of apparently healthy middle-aged men. Men with low-grade murmur had an increased risk of AVR, but no increase in risk of CVD death. Only 1.6% of men had moderate-grade murmur; these men had a very high risk of AVR and a 1.5-fold albeit non-significant increase in risk of CVD death.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
