The Dilemma in the Management of Thromboembolic Disease in the Setting of Concomitant Aortic Pseudoaneurysm.

Ascending aortic pseudoaneurysm (AAP) is a rare and serious complication of cardiothoracic surgeries or blunt chest trauma. We present a patient with paroxysmal atrial fibrillation, acute right pontine stroke, and acute pulmonary embolism (PE) with an incidental AAP that precluded the use of anticoagulation and surgery. The case findings substantiate the need for a CT-based assessment of aortic pathology after coronary artery bypass grafting (CABG) in the asymptomatic patient to determine the most appropriate treatment modalities. However, the high cost of CT imaging and the potential radiation exposure challenge its routine use in high-risk patients.

Timing of Percutaneous Coronary Intervention in Non-ST Elevation Acute Coronary Syndrome - Meta-Analysis and Systematic Review of Literature.

BACKGROUND: Percutaneous coronary intervention (PCI) is the standard procedure of care for most patients with non-ST elevation acute coronary syndrome (NSTE-ACS). However, the timing of PCI remains unclear. We performed this meta-analysis with available randomized controlled trials (RCTs) to compare early versus late coronary intervention in patients with NSTE-ACS. METHOD: A total of 13 RCTs were selected through PubMed/MEDLINE via OVID, EMBASE via OVID and Cochrane Central Register of Controlled Trials (inception to October 2018) search. Outcomes were analyzed using the relative risk (RR) and 95% CI. Pooled RRs were determined using M-H random-effects model, which can account for between study heterogeneity. RESULTS: We included 13 RCTs with 11,972 patients were included. There were 7101 patients were randomized into early invasive group and 4871 in late invasive group. There was a significant decrease in myocardial infarction with long-term follow up in early invasive group compared to the delayed invasive group (RR 0.847 [95% CI 0.74-0.95], p = 0.009) with no difference in mortality between early and late invasive group (5.41% vs 6.49%, RR 0.882 [95% CI, 0.76-1.02]). On subgroup analysis, data was available from 6 RCTs for GRACE (Global Registry of Acute Coronary Events) score and 8 RCTs for elevated troponin. Early intervention led to decrease in adverse events in patients with elevated GRACE score > 140 (Mantel-Haenszel pooled RR 0.88 [95% CI 0.82-0.95], p-value 0.002) but no difference was seen in patients with elevated troponin. CONCLUSION: It can be postulated from these results that early invasive strategy leads to decrease in myocardial infarction but without significant decrease in mortality. In patients with elevated GRACE score (>140), early intervention did show a trend towards decrease in major adverse cardiac events, whereas in patients with elevated troponin alone, similar association was not observed. However, adequately powered randomized controlled trial is necessary to validate these findings.

Burden of Peripheral Artery Disease in Sub-Saharan Africa and the Caribbean 1990 to 2015.

BACKGROUND: The estimated global prevalence of Peripheral artery disease (PAD) increased by 24% in span of 10 years (2000-2010) from 164 to 202 million. Despite scarcity of data on PAD in sub-Saharan Africa (SSA) and the Caribbean, estimates for PAD from these regions may be helpful for health-care providers. METHODS: The Global Burden of Disease Study 2015 quantified health loss from hundreds of diseases using systematic reviews and multilevel computer modeling. Estimated rates with 95% uncertainty intervals (UI) for PAD (ICD-10 I70.2) were examined for SSA and the Caribbean and compared to high-income North America (HINA). Disability-adjusted life years (DALYs) are years of healthy life lost representing total disease burden by combining years of life lost and years lived disabled. RESULTS: In 2015, estimated age-standardized DALYs per 100,000 due to PAD for males were as follows: Caribbean (34, UI: 29-39), HINA (36, UI: 30-42), and SSA (20, UI: 14-30). In contrast, DALYs in females were as follows: Caribbean (25, UI: 20-30), HINA (28, UI: 22-36), and SSA (17, UI: 11-26). For both sexes combined, the rate in Southern SSA was 55 (46-67). This reflects the extremely high rates in South Africa (males 90, UI: 77-107; females 63, UI: 53-75). CONCLUSION: Estimated rate of DALYs per 100,000 was lowest in SSA. Within SSA, the rate in South Africa was highest, exceeding even HINA. Caribbean rates were intermediate.
