Impact of Low Bone Mineral Content Index on Cardiovascular Outcomes in Patients With Coronary Artery Disease Undergoing Percutaneous Coronary Intervention.

The prognostic value of bone mineral content (BMC) for the clinical outcomes of patients with coronary artery disease (CAD) remains unknown. The present study evaluated the association between BMC index (BMCI) and cardiovascular events between January 2020 to June 2021, in consecutive patients (n = 257) with CAD undergoing percutaneous coronary intervention (PCI) at the Nagano Municipal Hospital. BMCI was measured using bioelectrical impedance analysis and calculated as the BMC divided by height squared. Patients were classified as low (<0.918) or high BMCI (≥0.918) groups according to the receiver operating characteristics curve analysis for the primary endpoint, major adverse cardiovascular events (MACE), including cardiovascular death, spontaneous myocardial infarction, stroke, and any revascularization. During a median follow-up of 744 days, the low BMCI group (n = 152) had an increased risk of MACE compared with the high group (n = 105) (19.7 vs 6.7%, P = .004). A low BMCI was significantly associated with MACE in the multivariable Cox and the Inverse Probability of Treatment Weighting analyses (hazard ratio: 3.16, 95% confidence interval: 1.15-8.67, P = .025). In conclusion, among patients with CAD undergoing PCI, BMCI was a predictor for cardiovascular events. Further research is required to determine whether medical interventions for BMC can improve patient prognosis.

Eosinophilic granulomatosis with polyangiitis presenting with eosinophilic myocarditis as the only organ involvement.

A 45-year-old man with a history of bronchial asthma had fever and elevated eosinophils on the day of surgery for sinusitis, resulting in cancellation of the surgery. Two days later, he was referred to our department for electrocardiographic abnormalities. We suspected eosinophilic myocarditis (EM) since he presented with fever, left ventricular hypokinesis, and hypertrophy on echocardiography, and eosinophilia with elevated cardiac enzymes. We immediately performed an endomyocardial biopsy that showed eosinophilic infiltration of the myocardium. He was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) since he suffered from asthma, eosinophilia, sinusitis, and EM. Methylprednisolone pulse therapy followed by oral prednisolone and intravenous cyclophosphamide pulse therapy decreased his eosinophils to within the normal range, and his symptoms subsequently improved. In EGPA, cardiac involvement is less commonly seen compared to other organ involvement. Moreover, patients with EGPA who have cardiac involvement generally have other organ involvement as well. In this report, the patient had only cardiac involvement as organ damage associated with EGPA, except for asthma and sinusitis in the prodromal phase, making it clear that patients with EGPA could present with cardiac involvement alone. Therefore, it is recommended to thoroughly examine for cardiac involvement in patients with suspected EGPA. Learning objective: We report a case of eosinophilic granulomatosis with polyangiitis (EGPA) presenting with cardiac involvement alone as organ damage, subsequently diagnosed with eosinophilic myocarditis as confirmed by an endomyocardial biopsy. EGPA usually involves other organs in addition to the cardiovascular system; however, patients with EGPA could present with cardiac involvement alone, as in this case. Thus, we should thoroughly investigate for cardiac involvement in patients with suspected EGPA.

Validation and Comparison of the Prognosis Predicting Ability of Inflammation-Based Scores Following Endovascular Treatment for Peripheral Artery Disease.

We assessed the prognostic ability of several inflammation-based scores and compared their long-term outcomes in patients with peripheral artery disease (PAD) following endovascular treatment (EVT). We included 278 patients with PAD who underwent EVT and classified them according to their inflammation-based scores (Glasgow prognostic score [GPS], modified GPS [mGPS], platelet to lymphocyte ratio [PLR], prognostic index [PI], and prognostic nutritional index [PNI]). Major adverse cardiovascular events (MACE) at 5 years were examined, and C-statistics in each measure were calculated to compare their MACE predictive ability. During the follow-up period, 96 patients experienced MACE. Kaplan-Meier analysis showed that higher scores of all measures were associated with a higher MACE incidence. Multivariate Cox proportional hazard analysis showed that GPS 2, mGPS 2, PLR 1, and PNI 1, compared with GPS 0, mGPS 0, PLR 0, and PNI 0, were associated with an increased risk of MACE. C-statistics for MACE for PNI (.683) were greater than those for GPS (.635, P = .021), mGPS (.580, P = .019), PLR (.604, P = .024), and PI (.553, P < .001). PNI is associated with MACE risk and has a better prognosis-predicting ability than other inflammation-scoring models for patients with PAD following EVT.
