    Abstract Few studies have comprehensively presented epidemiological indicators of myocardial infarction in Korea. However, multiple published articles and open-source secondary data on the epidemiology of myocardial infarction are now available. This review summarized the hospitalization incidence, prevalence, and mortality rate of myocardial infarction in Korea using articles and open-source data from the Health Insurance Service and the Department of Statistics, surveys of sample populations, registries of patients, and other sources. The epidemiological indicators of myocardial infarction were compared between Korea and other high-income countries. The incidence of hospitalization due to myocardial infarction in Korea was 43.2 cases per 100,000 population in 2016 and has consistently increased since 2011. It was 2.4 times higher among men than among women. The estimated prevalence among adults over 30 years of age ranged from 0.34% to 0.70% in 2020; it was higher among men and increased with age. The mortality in 2020, which was 19.3 per 100,000 population in 2020, remained relatively stable in recent years. Mortality was higher among men than among women. Based on representative inpatient registry data, the proportion of ST-elevated myocardial infarction decreased until recently, and the median time from symptom onset to hospital arrival was approximately 2 hours and 30 minutes. The hospitalization incidence, prevalence, and mortality rate of myocardial infarction were lower in Korea than in other countries, although there was an increasing trend. Comprehensive national-level support and surveillance systems are needed to routinely collect accurate epidemiological indicators.

    Abstract There has been a concern that angiotensin receptor blockers (ARB) may increase myocardial infarction (MI) in hypertensive patients compared with other classes of anti-hypertensive drugs. Angiotensin-converting enzyme inhibitor (ACEI) is recommended as a first-line inhibitor of renin-angiotensin system (RASI) in patients with acute MI (AMI), but ARB is also frequently used to control blood pressure. This study investigated the association of ARB vs. ACEI with the long-term clinical outcomes in hypertensive patients with AMI. Among patients enrolled in the nationwide AMI database of South Korea, the KAMIR-NIH, 4,827 hypertensive patients, who survived the initial attack and were taking ARB or ACEI at discharge, were selected for this study. ARB therapy was associated with higher incidence of 2-year major adverse cardiac events, cardiac death, all-cause death, MI than ACEI therapy in entire cohort. After propensity score-matching, ARB therapy was still associated with higher incidence of 2-year cardiac death (hazard ratio [HR], 1.60; 95% confidence interval [CI], 1.20-2.14; P = 0.001), all-cause death (HR, 1.81; 95% CI, 1.44-2.28; P < 0.001), and MI (HR, 1.76; 95% CI, 1.25-2.46; P = 0.001) than the ACEI therapy. It was concluded that ARB therapy at discharge in hypertensive patients with AMI was inferior to ACEI therapy with regard to the incidence of CD, all-cause death, and MI at 2-year. These data suggested that ACEI be a more appropriate RASI than ARB to control BP in hypertensive patients with AMI.

    Abstract The Guidelines of the 2019 European Society of Cardiology (ESC) and the 5th Society of Lipid and Atherosclerosis (KSoLA) for the Management of Dyslipidemia advocate a more intensive lipid-lowering strategy. However, there is a lack of evidence regarding the current status of lipid management in Korean patients in real-world practice. The Korean Society of Myocardial Infarction conducted a survey among its members of the Korean Society of Cardiology on the new lipid guidelines. Although most participants were aware of the changes in the ESC and the KSoLA guidelines, more than half of them did not agree with lowering the low-density lipoprotein cholesterol levels to < 55 mg/dL, because its safety and efficacy have not yet been proven in Koreans. A substantial disparity exists between lipid management guidelines and current clinical practices, highlighting the necessity for clinical research that specifically targets East Asians and Koreans to bridge this gap.

    Abstract Background: Cilostazol has a vasodilatory function that may be beneficial for patients with vasospastic angina (VSA). We conducted a randomized, open-label, controlled trial to compare the efficacy and safety of long-acting cilostazol and isosorbide mononitrate (ISMN) for VSA.
    Methods: The study included patients with confirmed VSA between September 2019 and May 2021. Participants were randomly assigned to receive long-acting cilostazol (test group, 200 mg once daily) or conventional ISMN therapy (control group, 20 mg twice daily) for 4 weeks. The clinical efficacy and safety were evaluated using weekly questionnaires.
    Results: Forty patients were enrolled in the study (long-acting cilostazol, n = 20; ISMN, n = 20). Baseline characteristics were balanced between the two groups. Long acting cilostazol showed better angina symptom control within the first week compared to ISMN [reduction of pain intensity score, 6.0 (4.0-8.0) vs. 4.0 (1.0-5.0), P = 0.005; frequency of angina symptom, 0 (0-2.0) vs. 2.0 (0-3.0), P = 0.027, respectively]. The rate of neurological adverse reactions was lower in the cilostazol group than in the ISMN group (headache or dizziness, 40 vs. 85%, P = 0.009; headache, 30 vs. 70%, P = 0.027).
    Conclusion: Long-acting cilostazol provided comparable control of angina and fewer adverse neurologic reactions within 4 weeks compared to ISMN. Long-acting cilostazol provides more intensive control of angina within 1 week, suggesting that it may be an initial choice for the treatment of VSA.

    Abstract Background: Anderson-Fabry disease (AFD) is an X-linked lysosomal storage disorder that results from a deficiency of α-galactosidase A enzyme activity in which glycosphingolipids gradually accumulate in multi-organ systems. Cardiac manifestations are the leading cause of mortality in patients with AFD. Among them, arrhythmias comprise a large portion of the heart disease cases in AFD, most of which are characterized by conduction disorders. However, atrial fibrillation as a presenting sign at the young age group diagnosed with AFD is uncommon.
    Case summary: We report a case of a 26-year-old man who was admitted with chest discomfort. Left ventricular hypertrophy was fulfilled in the criteria by the Sokolow-Lyon index and atrial fibrillation on the 12 Leads-electrocardiography (ECG) that was documented in the emergency room. After spontaneously restored to normal sinus rhythm, relationships between P and R waves, including a shorter PR interval on the ECG, were revealed. The echocardiographic findings showed thickened interventricular septal and left posterior ventricular walls. Based on the clues mentioned earlier, we realized the possibility of AFD. Additionally, we noticed the associated symptoms and signs, including bilateral mild hearing loss, neuropathic pain, anhidrosis, and angiokeratoma on the trunk and hands. He was finally diagnosed with classical AFD, which was confirmed by the gene mutation and abnormal enzyme activity of α-galactosidase A.
    Conclusion: This case is a rare case of AFD as a presentation with atrial fibrillation at a young age. Confirming the relationship between P and Q waves on the ECG through sinus rhythm conversion may help in differential diagnosis of the cause of atrial fibrillation and hypertrophic myocardium.

    Abstract Background Hydrophilic and lipophilic statins have similar efficacies in treating coronary artery disease. However, specific factors relevant to renal impairment and different arterial pathogeneses could modify the clinical effects of statin lipophilicity, and create differences in protective effects between statin types in patients with renal impairment.

    Abstract Intermittent left main coronary artery ostium obstruction (LMOO) caused by native aortic valve thrombus (NAVT) is an extremely rare condition. It may therefore be challenging to identify the cause using only coronary angiography, even though the clinical presentation and electrocardiography (ECG) strongly suggest myocardial infarction. We herein report a 53-year-old man with NAVT complicating intermittent occlusion of left main disease in preexisting coronary artery stenosis.

    Abstract Background: The prognostic utility of follow-up transthoracic echocardiography (FU-TTE) in patients with hypertrophic cardiomyopathy (HCM) is unclear, specifically in terms of whether changes in echocardiographic parameters in routine FU-TTE parameters are associated with cardiovascular outcomes.
    Methods: From 2010 to 2017, 162 patients with HCM were retrospectively enrolled in this study. Using echocardiography, HCM was diagnosed based on morphological criteria. Patients with other diseases that cause cardiac hypertrophy were excluded. TTE parameters at baseline and FU were analyzed. FU-TTE was designated as the last recorded value in patients who did not develop any cardiovascular event or the latest exam before event development. Clinical outcomes were acute heart failure, cardiac death, arrhythmia, ischemic stroke, and cardiogenic syncope.
    Results: Median interval between the baseline TTE and FU-TTE was 3.3 years. Median clinical FU duration was 4.7 years. Septal trans-mitral velocity/mitral annular tissue Doppler velocity (E/e'), tricuspid regurgitation velocity, left ventricular ejection fraction (LVEF), and left atrial volume index (LAVI) at baseline were recorded. LVEF, LAVI, and E/e' values were associated with poor outcomes. However, no delta values predicted HCM-related cardiovascular outcomes. Logistic regression models incorporating changes in TTE parameters had no significant findings. Baseline LAVI was the best predictor of a poor prognosis. In survival analysis, an already enlarged or increased size LAVI was associated with poorer clinical outcomes.
    Conclusions: Changes in echocardiographic parameters extracted from TTE did not assist in predicting clinical outcomes. Cross-sectionally evaluated TTE parameters were superior to changes in TTE parameters between baseline and FU at predicting cardiovascular events.

    Abstract Background: East Asians have shown different risk profiles for both thrombophilia and bleeding than Western counterparts.
    Objectives: The authors sought to evaluate the effect of low-dose aspirin for primary prevention between these populations.
    Methods: We searched randomized clinical trials (RCTs) for intervention with low-dose aspirin (≤100 mg once daily) in participants without symptomatic cardiovascular disease until December 31, 2021. The number of events between the arms was extracted for analysis. Pooled risk ratios (RRs) and risk differences (RDs) were analyzed in each population. Outcomes included a major adverse cardiovascular event (MACE), cardiovascular death, myocardial infarction, stroke, and major bleeding (intracranial hemorrhage and major gastrointestinal bleeding).
    Results: Two RCTs included 17,003 East Asians, and 9 RCTs had 117,467 Western participants. Aspirin treatment showed a similar effect in reducing the MACE rate (RR of East Asians: 0.87; 95% CI: 0.71-1.05; RR of Westerners: 0.90; 95% CI: 0.85-0.95) (
    Conclusions: Low-dose aspirin for primary prevention in East Asians must be cautiously prescribed because of the increased risk of major bleeding relative to Western counterparts.
