Intravascular Ultrasound-Guided versus Angiography-Guided Percutaneous Coronary Intervention for Stent Thrombosis Elevation Myocardial Infarction: An Updated Systematic Review and Meta-Analysis.

INTRODUCTION: Intravascular ultrasound (IVUS) provides intra-procedural guidance in optimizing percutaneous coronary interventions (PCI) and has been shown to improve clinical outcomes in stent implantation. However, current data on the benefit of IVUS during PCI in ST-elevation myocardial infarction (STEMI) patients is mixed. We performed meta-analysis pooling available data assessing IVUS-guided versus angiography-guided PCI in STEMI patients. METHODS: We conducted a systematic search on PubMed and Embase for studies comparing IVUS versus angiography-guided PCI in STEMI. Mantel-Haenszel random effects model was used to calculate risk ratios (RRs) with 95% confidence intervals (CIs) for outcomes of major adverse cardiovascular events (MACEs), death, myocardial infarction (MI), target vessel revascularization (TVR), stent thrombosis (ST) and in-hospital mortality. RESULTS: A total of 8 studies including 336,649 individuals presenting with STEMI were included for the meta-analysis. Follow-up ranged from 11 to 60 months. We found significant association between IVUS-guided PCI with lower risk for MACE (RR 0.82, 95% CI 0.76-0.90) compared with angiography-guided PCI. We also found significant association between IVUS-guided PCI with lower risk for death, MI, TVR, and in-hospital mortality but not ST. CONCLUSION: In our meta-analysis, IVUS-guided compared with angiography-guided PCI was associated with improved long-term and short-term clinical outcomes in STEMI patients.

Demographic and regional trends of peripheral artery disease-related mortality in the United States, 2000 to 2019.

INTRODUCTION: Peripheral artery disease (PAD) is a common progressive atherosclerotic disease associated with significant morbidity and mortality in the US; however, data regarding PAD-related mortality trends are limited. This study aims to characterize contemporary trends in mortality across sociodemographic and regional groups. METHODS: The Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER) was queried for data regarding PAD-related deaths from 2000 to 2019 in the overall sample and different demographic (age, sex, race/ethnicity) and regional (state, urban-rural) subgroups. Crude and age-adjusted mortality rates (CMR and AAMR, respectively) per 100,000 people were calculated. Associated annual percentage changes (APC) were computed using Joinpoint Regression Program Version 4.9.0.0 trend analysis software. RESULTS: Between 2000 and 2019, a total of 1,959,050 PAD-related deaths occurred in the study population. Overall, AAMR decreased from 72.8 per 100,000 in 2000 to 32.35 per 100,000 in 2019 with initially decreasing APCs followed by no significant decline from 2016 to 2019. Most demographic and regional subgroups showed initial declines in AAMRs during the study period, with many groups exhibiting no change in mortality in recent years. However, men, non-Hispanic (NH) Black or African American individuals, people aged ⩾ 85 years, and rural counties were associated with the highest AAMRs of their respective subgroups. Notably, there was an increase in crude mortality rate among individuals 25-39 years of age from 2009 to 2019. CONCLUSION: Despite initial improvement, PAD-related mortality has remained stagnant in recent years. Disparities have persisted across several demographic and regional groups, requiring further investigation.

Left Ventricle Mass Regression After Surgical or Transcatheter Aortic Valve Replacement in Veterans.

BACKGROUND: Differences in left ventricular mass regression (LVMR) between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) have not been studied. We present clinical and echocardiographic data from veterans who underwent TAVR and SAVR, evaluating the degree of LVMR and its association with survival. METHODS: We retrospectively reviewed TAVR (n = 194) and SAVR (n = 365) procedures performed in veterans from 2011 to 2019. After 1:1 propensity matching, we evaluated mortality and secondary outcomes. Echocardiographic data (median follow-up 957 days, interquartile range 483-1652 days) were used to evaluate LVMR, its association with survival, and predictors of LVMR. RESULTS: There was no difference between SAVR and TAVR patients in mortality (for up to 8 years), stroke at 30 days, myocardial infarction, renal failure, prolonged ventilation, reoperation, or structural valve deterioration. SAVR patients (67.3% [101 of 150]) were more likely to have LVMR than TAVR patients (55.7% [44 of 79], P = .11). The magnitude of LVMR was greater for the SAVR patients (median, -23.3%) than for the TAVR patients (median, -17.8%, P = .062). SAVR patients with LVMR had a survival advantage over SAVR patients without LVMR (P = .016). However, LVMR was not associated with greater survival in TAVR patients (P = .248). CONCLUSIONS: SAVR patients were more likely to have LVMR and had a greater magnitude of LVMR than TAVR patients. LVMR was associated with better survival in SAVR patients, but not in TAVR patients.

Age-Stratified Sex Disparities in Care and Outcomes in Patients With ST-Elevation Myocardial Infarction.

BACKGROUND: Women are undertreated and have worse clinical outcomes than men after acute myocardial infarction. It remains uncertain whether the sex disparities in treatments and outcomes persist in the contemporary era and whether they affect all age groups equally. METHODS: Using the National Inpatient Sample (NIS) registry, we evaluated 1,260,200 hospitalizations for ST-elevation myocardial infarction (STEMI) between 2010 and 2016, of which 32% were for women. The age-stratified sex differences in care measures and mortality were examined. Stepwise multivariable adjustment models, including baseline comorbidities, hospital characteristics, and reperfusion and revascularization therapies, were used to compare measures and outcomes between women and men across different age subgroups. RESULTS: Overall, women with STEMI were older than men and had more comorbidities. Women were less likely to receive fibrinolytic therapy, percutaneous coronary intervention (PCI), and coronary artery bypass surgery across all age subgroups. Women with STEMI overall experienced higher unadjusted in-hospital mortality (11.1% vs 6.8%; adjusted odds ratio [OR] = 1.039, 95% confidence interval [CI]: 1.003-1.077), which persisted after multivariable adjustments. However, when stratified by age, the difference in mortality became non-significant in most age groups after stepwise multivariable adjustment, except among the youngest patients 19-49 years of age with STEMI (women vs men: 3.9% vs 2.6%; adjusted odds ratio = 1.259, 95% confidence interval: 1.083-1.464). CONCLUSIONS: Women with STEMI were less likely to receive reperfusion and revascularization therapies and had higher in-hospital mortality and complications compared with men. Younger women with STEMI (19-49 years of age) experienced higher in-hospital mortality that persisted after multivariable adjustment.

Relation Between Cardiology Follow-Up Visits, Evidence-Based Statin Prescribing, and Statin Adherence (from the Veterans Affairs Health Care System).

Statin use remains suboptimal in patients with atherosclerotic cardiovascular disease (ASCVD). We assessed whether outpatient care with a cardiology provider is associated with evidence-based statin prescription and statin adherence. We identified patients with ASCVD aged ≥18 years receiving primary care in 130 facilities and associated community-based outpatient clinics in the entire Veterans Affairs Health Care System between October 1, 2013 and September 30, 2014. Patients were divided into: (1) patients with at least 1 outpatient cardiology visit and (2) patients with no outpatient cardiology visits in the year before the index primary care visit. We assessed any- and high-intensity statin prescription adjusting for several patient- and facility-level covariates, and statin adherence using proportion of days covered (PDC). We included 1,249,061 patients with ASCVD (mean age: 71.9 years; 98.0% male). After adjusting for covariates, patients who visited a cardiology provider had greater odds of being on a statin (87.4% vs 78.4%; Odds ratio [OR] 1.25, 95% Confidence interval [CI] 1.24 to 1.26), high-intensity statin (34.5% vs 21.2%; OR: 1.21, 95% CI 1.21 to 1.22), and higher statin adherence (mean PDC 0.76 ± 0.29 vs 0.70 ± 0.34, PDC ≥0.8: 62.0% vs 57.3%; OR 1.09, 95% CI 1.09 to 1.11). A dose response relation was seen with a higher number of cardiology visits associated with a higher statin use and statin adherence. In conclusion, compared with outpatient care delivered by primary care providers alone, care delivered by a cardiology provider for patients with ASCVD is associated with a higher likelihood of guideline-based statin use and statin adherence.

Giant mesenteric fibromatosis: Report of a case and review of the literature.

Mesenteric fibromatosis poses a diagnostic and therapeutic challenge. This paper presents a 35-year-old female complaining of vague abdominal pain of 2 mo duration. Her computed tomography scan and magnetic resonance imaging revealed a pelvi-abdominal heterogenous mass with significant displacement of the small bowel and urinary bladder. She underwent surgical excision of the mass with resection and anastomosis of the involved loop of the small intestine. Histological examination confirmed mesenteric fibromatosis without infiltration of the bowel. The patient remained well during the 6 mo follow-up.

Blepharophimosis-ptosis-epicanthus inversus syndrome in a Pakistani pedigree.

Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare developmental ocular disorder. We report this condition affecting 4 members of a Pakistani family across three generations. A 2-year-old girl was brought to the clinic by her father for the correction of her shortened palpebral fissures. Examination findings were consistent with BPES. The girl's father, paternal grandfather and paternal aunt also had identical features. The distance between the medial canthi of the index case was 30 mm, and the lengths of vertical and horizontal palpebral fissure were 6 mm and 20 mm, respectively. BPES must be considered an important differential diagnosis in patients presenting with blepharoptosis and blepharophimosis.
