The coronavirus infection 2019 (COVID-19) pandemic has led to the development of mRNA vaccines with proven efficacy. However, it remains unclear whether patients who developed pericarditis after the first COVID-19 mRNA would be fit to receive the second vaccination. Herein, we present the case of a 64-year-old man who visited our emergency department with substernal chest discomfort that began 4 days after his first mRNA COVID-19 vaccination. Acute pericarditis was diagnosed based on symptoms and ST-segment elevation on an electrocardiogram. Chest pain improved 2 days after treatment.Since there are no guidelines on whether to administer an additional vaccination to a patient who developed pericarditis after the initial vaccination, we considered whether or not to administer the additional vaccination. We informed the patient about the risks and benefits and decided to administer the second dose. He did not experience any major adverse reactions. The indications for the second vaccination need to be thoroughly considered.

Aim: The effects of statin on small dense low-density lipoprotein cholesterol (sd-LDL-C) and remnant-like particle cholesterol (RLP-C) levels in heterozygous familial hypercholesterolemia (FH) have not been examined. This study aimed to clarify the effects of statin on sd-LDL-C and RLP-C levels in heterozygous FH.Methods: Seventeen patients with heterozygous FH were randomly assigned to 2 mg/day pitavastatin or 10 mg/day atorvastatin. At baseline and 12 weeks after treatment with statin, we measured sd-LDL-C and RLP-C levels.Results: Sd-LDL-C levels significantly decreased from 43 ± 24 to 16 ± 10 mg/dL (−63%, p=0.001) in the pitavastatin group, and from 44 ± 17 to 19 ± 10 mg/dL (−55%, p<0.001) in the atorvastatin group. RLP-C levels decreased from 8.4 ± 2.8 to 6.6 ± 2.7 mg/dL (−16%, p=0.156) in the pitava-statin group, and from 9.8 ± 4.7 to 5.9 ± 5.4 mg/dL (−45%, p=0.044) in the atorvastatin group. There were no significant differences in percent changes of sd-LDL-C (p=0.370) and RLP-C levels (p=0.097) between the two groups.Conclusions: Sd-LDL-C measured by the heparin-magnesium precipitation method and RLP-C levels in heterozygous FH were decreased by 12 weeks of statin therapy. Statin might have additional anti-atherogenic effects by reducing not only LDL-C but also sd-LDL-C and RLP-C.

Aim: Coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFRCT) accurately diagnoses ischemic lesions of intermediate stenosis severity. However, significant determinants of FFRCT have not been fully evaluated.Methods: This was a sub-analysis of the Treatment of Alogliptin on Coronary Atherosclerosis Evaluated by Computed Tomography-Based Fractional Flow Reserve trial. Thirty-nine diabetic patients (117 vessels) with intermediate coronary artery stenosis [percent diameter stenosis (%DS) <70%] in whom FFRCT was measured were included in this study. CCTA-defined, vessel-based volumetric and morphological characteristics of plaques were examined to determine their ability to predict FFRCT.Results: Patient-based, multivariate linear regression analysis showed that hemoglobinA1c, triglycerides, and the estimated glomerular filtration rate were significant independent factors associated with FFRCT. Vessel-based, univariate linear regression analysis showed that the total atheroma volume (r=−0.233, p=0.01) and the percentage atheroma volume (PAV) (r=−0.284, p=0.002) as well as %DS (r=−0.316, p=0.006) were significant determinants of FFRCT. Among the plaque components, significant negative correlations were observed between FFRCT and low- (r=−0.248, p=0.007) or intermediate-attenuation plaque volume (r=−0.186, p=0.045), whereas calcified plaque volume was not associated with FFRCT. In the left anterior descending coronary artery (LAD), the plaque volume of each component was associated with FFRCT.Conclusions: Plaque volume, PAV, and %DS were significant determinants of FFRCT. Plaque morphology, particularly in LAD, was associated with FFRCT in diabetic patients with intermediate coronary artery stenosis.
