“…Frequently, MR is present in the early phases of AMI, though its incidence is dependent upon the detection technique. Mitral regurgitation, within several days to one week after AMI, has been reported to be present in 9% to 55% of patients by auscultation (11,21,22), and in 20% to 56% of patients by echocardiography (11,23,24). More recently, two angiographic studies have detected MR in 13% and 17.9% of patients within 7 h of admission for AMI (9,10), and in 19.4% of patients at a mean of four days (12).…”

“…2,3 In 1 study, which excluded patients who were older than 65 years, who had previous MI, multiple comorbidities, or severe congestive heart failure, 19% of patients had MR at 5 to 8 weeks after the event. 4 Even in these young and relatively healthy patients after first MI, mortality at 15 months was 3 times higher for patients with IMR compared with those without IMR (9.8% vs 3.2%). In addition, HF developed relatively rapidly, and by 15 months, 20% of patients with IMR had mild to moderate HF compared with 3% of patients without IMR.…”

“…In addition, HF developed relatively rapidly, and by 15 months, 20% of patients with IMR had mild to moderate HF compared with 3% of patients without IMR. 4 Timely reperfusion is the primary goal of therapy for acute ST-elevation MI (STEMI). In the current era, this is best accomplished by percutaneous coronary intervention (PCI) when resources are available.…”

“…7 Longer-term studies at 1, 2, and 3 months, and up to 1 year, demonstrate that IMR persists in many patients. 4,8 The most recent American College of Cardiology/American Heart Association focused update of the management of patients with valvular heart disease does not specifically address the subset of patients with IMR after primary PCI. 9 This gap may be largely because of the paucity of data on these patients to allow the development of practice guidelines.…”

Summary: A total of 61 patients with first-time mild to moderate acute myocardial infarction and no reinfarction within the following 2 months were studied prospectively by Doppler echocardiography before hospital discharge and after 2 months to evaluate the prevalence of mitral regurgitation. Twenty-one age-matched healthy subjects served as controls. At baseline, the prevalence of Dopplerrecorded mitral regurgitation was 74% and 29% in patients and controls, respectively. In the patients, the regurgitant flow measured by color flow Doppler was 1.04 cm2 (range 0.2-8 cm2) and occupied 7.5% (range 2-45%) of the left atrial area. Corresponding figures for controls were 0.35 cm2 (0.1-0.6) and 2.4% (0.7-4.5), respectively. On continuous wave Doppler, most patients (33/45) had Doppler signals similar to those of healthy controls. The prevalence of mitral regurgitation was about the same in anterior and inferior infarction (75 and 72% respectively). In the patients, the prevalence was similar after 2 months (79%) with minor changes in the Doppler characteristics of the regurgitation (regurgitant flow 1.12 cm2 and occupying 8.1 % of left atrial area). The study demonstrates that in a group of patients with first-time mild to moderate myocardial infarction the prevalence of Doppler-recorded mitral regurgitation is high and mild in seventy in the majority of the cases. The changes remain almost similar even after 2 months.
