Prognostic Value of the Pattern of Non-Adherence to Anti-Platelet Regimen in Stented Patients (PARIS) Bleeding Risk Score for Long-Term Mortality After Percutaneous Coronary Intervention.

The Patterns of non-Adherence to Anti-Platelet Regimen in Stented Patients (PARIS) bleeding risk score has been proposed to predict the risk of bleeding events after percutaneous coronary intervention (PCI). However, the prognostic value of the PARIS bleeding risk score for long term all-cause mortality, cardiac mortality and hospitalization due to heart failure has not yet been evaluated. Therefore, the aim of the present study was to evaluate the prognostic value of the PARIS bleeding risk score for all-cause and cardiac mortalities and hospitalization due to heart failure after PCI. Consecutive 1061 patients who had undergone PCI were divided into 3 groups based on the PARIS bleeding risk score; low (n = 112), intermediate (n = 419) and high-risk groups (n = 530). We prospectively followed up the 3 groups for all-cause and cardiac mortalities and hospitalization due to heart failure. Kaplan-Meier analysis revealed that all of the outcomes were highest in the high-risk group among the 3 groups (P < 0.001, P < 0.001 and P < 0.001 respectively). Multivariable Cox proportional hazard analysis, adjusted for confounding factors, revealed that all-cause mortality of the intermediate or high-risk groups was higher than those of the low-risk group (adjusted hazard ratio 6.06 and 12.50, P = 0.013 and P < 0.001, respectively). The PARIS bleeding risk score is a significant indicator of prognosis for all-cause mortality in patients after PCI.

The Prognostic Impact of D-Dimer on Long-Term Mortality in Patients with Coronary Artery Disease after Percutaneous Coronary Intervention.

D-dimer is a common measurable coagulation marker that is associated with the risk of thrombotic events in vascular diseases. However, the impact of D-dimer on long-term mortality in coronary artery disease (CAD) patients remains unclear. This study investigated the association between D-dimer and long-term all-cause, cardiac and cancer mortality in CAD patients. Continuous 1,440 patients with CAD who underwent percutaneous coronary intervention (PCI) and survived to discharge were enrolled. These patients were divided into 3 groups based on plasma D-dimer levels at admission. Baseline D-dimer levels were grouped by tertiles: first (D-dimer < 0.7 µg/mL, n = 455), second (0.7 ≤ D-dimer < 1.2, n = 453), and third (1.2 ≤ D-dimer, n = 532). In a Kaplan-Meier analysis (mean follow-up periods 1,572 days), all-cause, cardiac and cancer mortalities were significantly higher in the third tertile than others (P < 0.001, P < 0.001 and P < 0.001, respectively). In multivariable Cox proportional hazard analyses after adjusting for confounding factors, a high D-dimer level was an independent predictor of all-cause, cardiac, non-cardiac and cancer mortalities (HR 3.23, P < 0.001; HR 3.06, P = 0.008; HR 3.11, P = 0.026). In a subgroup analysis, there were no interactions except for the gender subgroup in cancer mortality. In patients with CAD after PCI, high D-dimer levels were associated with long-term all-cause, cardiac and cancer mortality.

Differences in treatment and prognosis by the experience of falls or bone fracture in elderly patients with atrial fibrillation.

Treatment and prognosis of elderly patients with atrial fibrillation (AF) may differ by the experience of fall or bone fracture. However, their current status is still unclear. From our institute database between 2010 and 2015, 674 AF patients with age ≥ 70 years were selected and were divided into those who experienced fall or fracture during the observation period (F/F group; n = 49) and those who did not (non-F/F group; n = 625). We compared the treatment and prognosis between the 2 groups. Patients in the F/F group were older (79 vs 76 years, P < 0.001) and had more comorbidities compared with those in the non-F/F group. The prescription rate of oral anticoagulant was similar between the two groups (77.6% vs 68.2%, P = 0.201), where warfarin was predominant. The F/F group was not associated with higher incidence of ischemic stroke. The F/F group was associated with a higher incidence of heart failure events (adjusted odds ratio (OR) 3.88; 95% confidence intervals (Cl) 1.70-8.85; P = 0.001), and cardiovascular events (OR 3.43; 95% Cl 1.71-6.85; P < 0.001). In elderly AF patients in a cardiovascular hospital, the experience of fall or fracture did not affect the prescription of oral anticoagulants and the incidence of ischemic stroke, but it was significantly associated with increase of heart failure.

A case of COVID-19-associated fulminant myocarditis due to SARS-CoV-2 omicron BA.2 sub-lineage in an unvaccinated female.

COVID-19-associated myocarditis can be a lethal complication in previous variants, but it is not well understood in the Omicron variant. We present an unvaccinated case of COVID-19-associated fulminant myocarditis due to the Omicron BA.2 sub-lineage requiring mechanical circulatory support (MCS). A 66-year-old female without vaccination against SARS-CoV-2 was hospitalized due to COVID-19. On the next day, she was transferred to our hospital due to the development of fulminant myocarditis. After arrival, she was treated with Impella CP and venoarterial extracorporeal membrane oxygenation due to unstable hemodynamics. In addition to MCS, we treated her with inotropes, methylprednisolone, tocilizumab, and remdesivir. Left ventricular contraction gradually improved, and MCS was removed on day 8. Endomyocardial biopsy showed mild interstitial infiltration of CD3+-T lymphocytes and CD68+-macrophages with no remarkable necrosis or fibrosis. This case showed similar histological characteristics to COVID-19-associated myocarditis before the Omicron variant. The vaccination against the Omicron variant should be considered to prevent the development of severe illness, including fulminant myocarditis. Learning objective: Although the Omicron variant is thought to be generally less severe, COVID-19-associated fulminant myocarditis, as in this case, can occur. The vaccination against the Omicron variant should be considered to prevent from developing severe illness.

Clinical usefulness of the pattern of non-adherence to anti-platelet regimen in stented patients (PARIS) thrombotic risk score to predict long-term all-cause mortality and heart failure hospitalization after percutaneous coronary intervention.

BACKGROUND: The Patterns of non-Adherence to Anti-Platelet Regimen in Stented Patients (PARIS) thrombotic risk score has been proposed to estimate the risk of stent thrombotic events after percutaneous coronary intervention (PCI). However, the prognostic value of the PARIS thrombotic risk score for long term all-cause and cardiac mortalities, as well as hospitalization due to heart failure, has not yet been evaluated. Therefore, the aim of the present study was to evaluate the prognostic value of the PARIS thrombotic risk score for all-cause and cardiac mortalities and hospitalization due to heart failure following PCI. METHODS AND RESULTS: Consecutive 1,061 patients who underwent PCI were divided into three groups based on PARIS thrombotic risk score; low- (n = 320), intermediate- (n = 469) and high-risk (n = 272) groups. We followed up on all three groups for all-cause mortality, cardiac mortality and hospitalization due to heart failure. Kaplan-Meier analysis showed that all outcomes were highest in the high-risk group (P < 0.001, P = 0.022 and P < 0.001, respectively). Multivariate Cox proportional hazard analysis, adjusted for confounding factors, showed that the risk of all-cause mortality and hospitalization due to heart failure of the high-risk group were higher than those of the low-risk group (hazard ratios 1.76 and 2.14, P = 0.005 and P = 0.017, respectively). CONCLUSION: The PARIS thrombotic risk score is a significant prognostic indicator for all-cause mortality and hospitalization due to heart failure in patients after PCI.
