Intensity of Statin Treatment in Korean Patients with Acute Myocardial Infarction and Very Low LDL Cholesterol.

Objective: Data on the intensity of statin therapy for patients with acute myocardial infarction (MI) and very low baseline low-density lipoprotein (LDL) cholesterol level are lacking. We sought to assess the impact of statin intensity in patients with acute MI and LDL cholesterol <70 mg/dL.

Methods: A total of 1,086 patients with acute MI and baseline LDL cholesterol <70 mg/dL from the Korea Acute Myocardial Infarction Registry-National Institute of Health database were divided into less intensive statin (expected LDL reduction <40%, n=302) and more intensive statin (expected LDL reduction ≥40%, n=784) groups.

Clinical Impact of Atypical Chest Pain and Diabetes Mellitus in Patients with Acute Myocardial Infarction from Prospective KAMIR-NIH Registry.

Atypical chest pain and diabetic autonomic neuropathy attract less clinical attention, leading to underdiagnosis and delayed treatment. To evaluate the long-term clinical impact of atypical chest pain and diabetes mellitus (DM), we categorized 11,159 patients with acute myocardial infarction (AMI) from the Korea AMI-National Institutes of Health between November 2011 and December 2015 into four groups (atypical DM, atypical non-DM, typical DM, and typical non-DM). The primary endpoint was defined as patient-oriented composite endpoint (POCE) at 2 years including all-cause death, any myocardial infarction (MI), and any revascularization.

Immediate multivessel intervention versus culprit-vessel intervention only in patients with ST-elevation myocardial infarction and multivessel coronary disease: data from the prospective KAMIR-NIH registry.

Background: The safety and efficacy of immediate multivessel coronary intervention (MVI) remain controversial in patients with ST-elevation myocardial infarction (STEMI) and multivessel disease (MVD). This study aimed to investigate the clinical outcomes of immediate MVI compared with culprit-vessel intervention only (CVI-O) in diverse subgroups with STEMI and MVD.

Patients And Methods: We compared immediate MVI (n=260) and CVI-O (n=931) regarding 1-year major adverse cardiac event rates for cardiac death, recurrent myocardial infarction (MI), and repeat revascularization in 1191 STEMI patients with MVD using data from the Korea Acute Myocardial Infarction-National Institutes of Health registry (2011-2015).
