In this report, we introduce a case of thickening of the involved left ventricular apical segment on echocardiography and deep T-wave inversions in precordial leads on electrocardiography transiently seen in the course of recovery from biventricular takotsubo cardiomyopathy, mimicking apical hypertrophic cardiomyopathy. This result suggests that the echocardiographic finding of transient myocardial edema can be identified by cardiac magnetic resonance imaging in takotsubo cardiomyopathy. Additio

BACKGROUND: The purpose of this study was to evaluate whether performing an assessment of myocardial deformation using speckle tracking imaging during the recovery period after dobutamine stress echocardiography (DSE) allows detection of significant coronary artery disease (CAD) in patients with chest discomfort. METHODS: DSE and coronary angiography were performed in 44 patients with chest discomfort. The mean global longitudinal peak systolic strain (GLS) was measured at rest, at low stress (d

BACKGROUND: This study evaluated whether blunted autonomic activity as measured by heart rate recovery (HRR) was associated with increased arterial stiffness, especially increased exercise-induced arterial stiffness, in normotensive patients without overt atherosclerosis. METHODS: One hundred fifty-four normotensive patients without overt atherosclerosis who had undergone a treadmill exercise test were consecutively enrolled. HRR was measured at one minute after exercise. Brachial-ankle pulse wa

The leading cause of morbidity and mortality in patients with acromegaly is cardiovascular complications. Myocardial exposure to excessive growth hormone can cause ventricular hypertrophy, hypertension, arrhythmia, and diastolic dysfunction. However, congestive heart failure as a result of systolic dysfunction is observed only rarely in patients with acromegaly. Most cases of acromegaly exhibit high levels of serum insulin-like growth factor-1 (IGF-1). Acromegaly with normal IGF-1 levels is rare

This study aimed to investigate the relationship between a complex percutaneous coronary intervention (C-PCI) and long-term clinical outcomes in the AMI cohort. A total of 10,329 patients were categorized into the C-PCI and non-C-PCI groups. The primary ischemic endpoint was a composite of major adverse cardiac events (MACEs, cardiac death, myocardial infarction, stent thrombosis and revascularization). The primary bleeding endpoint was the risk of overt bleeding (BARC 2, 3 or 5). The median fol

This study aimed to investigate the efficacy of the HFA-PEFF score in predicting the long-term risks in patients with acute myocardial infarction (AMI) and an HFA-PEFF score ≥ 2. The subjects were divided according to their HFA-PEFF score into intermediate (2−3 points) and high (4−6 points) score groups. The primary outcome was all-cause mortality. Of 1018 patients with AMI and an HFA-PEFF score of ≥2, 712 (69.9%) and 306 (30.1%) were classified into the intermediate and high score groups, respe

Purpose To evaluate non-alcoholic fatty pancreas disease severity on ultrasound (US-determined NAFPD) as a risk factor for coronary heart disease (CHD) and to evaluate its predictive value for intermediate/high CHD risk compared with US-determined non-alcoholic fatty liver disease (US-determined NAFLD) severity.

RATIONALE: Coronary artery ectasia (CAE), characterized by diffuse dilation, can be associated with total thrombotic occlusion, leading to acute coronary syndrome. In such cases, distal vessel morphology can be highly unpredictable, potentially causing confusion during percutaneous coronary intervention (PCI). PATIENT CONCERNS: A 47-year-old man presented with sudden chest pain. Acute coronary syndrome was suspected based on symptom and elevated troponin I levels. DIAGNOSES: Coronary angiography

Patients with diabetes have many different kinds of complications involving multiple organs, but those involving the musculoskeletal system are relatively uncommon. Diabetic muscle infarction (DMI) is a rare, painful, and potentially serious condition in patients with poorly controlled diabetes mellitus. A 35-year-old man diagnosed with type 2 diabetes eight years ago, visited with severe muscle pain in the right anteromedial thigh without any event of trauma. He had been treated with metformin,

Introduction: An athlete's heart (AH) varies depending on race, sex, age, and the type and intensity of training. Given that soccer is a common sport, evaluation of cardiac function in soccer players is important; however, few studies have analyzed adolescent soccer players. Therefore, this study, aimed to identify early changes in AH in soccer players by evaluating the echocardiographic findings of adolescent Asian female soccer players for whom existing data are scarce. Methods: We evaluated 2

Rheumatoid arthritis (RA) causes coronary artery atherosclerosis with a similar risk as diabetes or hypertension. However, coronary artery disease (CAD) is rare in young patients, especially in those presenting as chronic total occlusion (CTO). We report a rare case of aborted sudden cardiac death in a 26-year-old patient with a six-year history of RA. He had no cardiovascular risk factors apart from RA. He was diagnosed with severe ischaemic heart failure (HF) due to recent myocardial ischaemia

In patients with acute coronary syndrome (ACS), lipid-lowering therapy plays an important role in the prevention of the recurrence of cardiovascular disease. Recent guidelines recommend the use of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in patients with ACS if their low-density lipoprotein cholesterol (LDL-C) levels are not adequately controlled with statins and ezetimibe. Based on this, we report a case in which administering a PCSK9 inhibitor successfully lowered the p

Ticagrelor, a P2Y12 antagonist, is well known for its rapid, high-potent inhibition of platelet aggregation by pharmacokinetic studies [1]. In the PLATO study, ticagrelor, compared to clopidogrel, reduced the incidence of myocardial infarction, stroke, cardiovascular death and definite stent thrombosis, during 12-month follow-up in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) [2,3]. To date, the effect of early ticagrelor administration versus t

Many patients with angina or evidence of myocardial ischemia on noninvasive tests have no obstructive coronary artery disease. Ischemia with non-obstructive coronary arteries (INOCA) has been underrecognized despite its association with poor quality of life and effect on cardiovascular events. Two major mechanisms, coronary microvascular dysfunction (CMD) and coronary vasospasm, are keys to INOCA pathophysiology. Although noninvasive tests, such as stress echocardiography, cardiac positron emiss
