Pediatric Tachycardia?
The electrocardiogram in the figure is from a previously healthy 15-year-old boy who reports palpitations and dizziness over the past two weeks. How would you interpret this tachycardia?

New Injectable Cholesterol-Lowering Drug Trial
A comparison of inclisiran therapy to placebo and ezetimibe therapy over six months in primary prevention patients at low risk of atherosclerotic cardiovascular disease and not taking lipid-lowering therapy has shown that inclisiran subcutaneously every six months reduces low-density lipoprotein cholesterol more than ezetimibe and is comparable to the reported results of high-dose statins taken daily.

CT Coronary Artery Calcium Progression After an Initial Score of Zero
A large Korean study of asymptomatic subjects undergoing more than one computed tomography (CT) coronary calcium scoring scan as part of an employment-based health screening has shown that most had scores of 0, and that during a maximum follow-up of 12 years, the majority stayed at 0 on a repeat scan. Also, in those with a coronary artery calcium score of 0 initially, clinically significant scores (> 100) were only found in 4% of scans at 10-year follow-up.

What Kind of Block?
The electrocardiogram in the figure was obtained from an older adult who presented for evaluation of syncope. What kind of atrioventricular (AV) block is present? Or is the rhythm something other than an AV block?

Looking Beyond LDL in Cardiovascular Risk Screening for Women
In a 30-year prospective study of nearly 28,000 initially healthy U.S. women, baseline levels of high-sensitivity C-reactive protein, low-density lipoprotein cholesterol or lipoprotein(a) independently and additively predicted major cardiovascular events.

And Then What Happens?
You are consulted on the electrocardiogram (ECG) in the figure — but without the benefit of any clinical information. This tracing was assessed as showing AFib (atrial fibrillation) with a controlled ventricular response. Do you agree?

Use of Coronary Calcium Score in Familial Coronary Artery Disease
A randomized trial of computed tomography (CT) coronary artery calcium score augmented management vs. usual care of primary prevention patients at moderate risk of a coronary event and with a family history of premature coronary events has shown that, after three years of follow-up, the calcium score group had lower low-density lipoprotein cholesterol levels and smaller total plaque volumes by CT angiography.

The Cause of the ‘Burning?’
The electrocardiogram (ECG) in the figure is from a man with a new and severe “burning” chest discomfort. On seeing this ECG, the paramedic team requested activating the cath lab. Would you have done the same?

Arrhythmia Recurrence After Catheter Ablation of Atrial Fibrillation
An integrated nationwide medical and pharmacy claims database analysis of patients with new atrial fibrillation undergoing catheter ablation as first-line therapy has shown that 17% of patients required repeat ablation for recurrent atrial fibrillation despite the frequent use of antiarrhythmic drugs.

Ten-Year Outcomes of the SCOT-HEART Study
The 10-year follow-up of the SCOT-HEART Study of new-onset chest pain patients randomized to standard care vs. the addition of coronary computed tomography angiography (CTA) has shown that coronary heart disease-related death, myocardial infarction, and other adverse cardiovascular outcomes are reduced with CTA use, perhaps because preventive therapy is increased.
