Asymptomatic Coronary Artery Disease in a Pregnant Patient

Acute myocardial infarction during pregnancy has been reported and has been shown to be associated with poor maternal and fetal outcomes. However, the vast majority of these patients do not have previously recognized ischemic heart disease. Pregnancy and delivery pose significant cardiac stress and risk to the mother and fetus. However, it is unknown how available therapies can be utilized in the pregnant patient with identified ischemic heart disease to minimize these risks. Case Report: We present a 39-year-old asymptomatic diabetic female with a positive stress echocardiogram at 16 weeks of pregnancy who remained asymptomatic throughout pregnancy with medical management and went on to have a normal vaginal delivery in the process suffering a small non-ST elevation myocardial infarction with pulmonary edema following delivery due to volume overload. She ultimately underwent cardiac catheterization and successful four-vessel CABG 1 months after her delivery. Conclusion: We present this patient to suggest a successful strategy of managing a patient with non-revascularized asymptomatic coronary artery disease during pregnancy. In addition to reviewing the appropriate medical therapy during pregnancy, we discuss the data on revascularization procedures as well as recommendations for delivery and stress testing for such patients. Tritt ein akuter Herzinfarkt während der Schwangerschaft auf, ist die Prognose für Mutter und Kind ungünstig. Die Mehrheit dieser Patientinnen hat in der Vorgeschichte keine koronare Herzerkrankung. Die Schwangerschaft und Geburt bedeuten eine starke kardiale Belastung und ein Risiko für Mutter und Kind. Unbekannt ist jedoch bisher, welche Therapien schwangeren Patientinnen angeboten werden können, die eine ischämische Herzerkrankung haben, um das Risiko zu mindern.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42466/1/20270548.pd

Association of Operator and Hospital Experience With Procedural Success Rates and Outcomes in Patients Undergoing Percutaneous Coronary Interventions for Chronic Total Occlusions: Insights From the Blue Cross Blue Shield of Michigan Cardiovascular Consortium

BACKGROUND: An inverse relationship has been described between procedural success and outcomes of all major cardiovascular procedures. However, this relationship has not been studied for percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). METHODS: We analyzed the data on patients enrolled in Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry in Michigan (January 1, 2010 to March 31, 2018) to evaluate the association of operator and hospital experience with procedural success and outcomes of patients undergoing CTO-PCI. CTO-PCI was defined as intervention of a 100% occluded coronary artery presumed to be ≥3 months old. RESULTS: Among 210 172 patients enrolled in the registry, 7389 (3.5%) CTO-PCIs were attempted with a success rate of 53%. CTO-PCI success increased with operator experience (45% and 65% in the lowest and highest experience tertiles) and was the highest for highly experienced operators at higher experience centers and the lowest for inexperienced operators at low experience hospitals. Multivariable logistic regression models (with spline transformed prior operator and institutional experience) demonstrated a positive relationship between prior operator and site experience and procedural success rates (likelihood ratio test=141.12, df=15, P\u3c0.001) but no relationship between operator and site experience and major adverse cardiac event (likelihood ratio test=19.12, df=15, P=0.208). CONCLUSIONS: Operator and hospital CTO-PCI experiences were directly related to procedural success but were not related to major adverse cardiac event among patients undergoing CTO-PCIs. Inexperienced operators at high experience centers had significantly higher success but not major adverse cardiac event rates compared with inexperienced operators at low experience centers. These data suggested that CTO-PCI safety and success could potentially be improved by selective referral of these procedures to experienced operators working at highly experienced centers

Population Health Metrics Research Consortium gold standard verbal autopsy validation study: design, implementation, and development of analysis datasets

Background: Verbal autopsy methods are critically important for evaluating the leading causes of death in populations without adequate vital registration systems. With a myriad of analytical and data collection approaches, it is essential to create a high quality validation dataset from different populations to evaluate comparative method performance and make recommendations for future verbal autopsy implementation. This study was undertaken to compile a set of strictly defined gold standard deaths for which verbal autopsies were collected to validate the accuracy of different methods of verbal autopsy cause of death assignment.Methods: Data collection was implemented in six sites in four countries: Andhra Pradesh, India; Bohol, Philippines; Dar es Salaam, Tanzania; Mexico City, Mexico; Pemba Island, Tanzania; and Uttar Pradesh, India. The Population Health Metrics Research Consortium (PHMRC) developed stringent diagnostic criteria including laboratory, pathology, and medical imaging findings to identify gold standard deaths in health facilities as well as an enhanced verbal autopsy instrument based on World Health Organization (WHO) standards. A cause list was constructed based on the WHO Global Burden of Disease estimates of the leading causes of death, potential to identify unique signs and symptoms, and the likely existence of sufficient medical technology to ascertain gold standard cases. Blinded verbal autopsies were collected on all gold standard deaths.Results: Over 12,000 verbal autopsies on deaths with gold standard diagnoses were collected (7,836 adults, 2,075 children, 1,629 neonates, and 1,002 stillbirths). Difficulties in finding sufficient cases to meet gold standard criteria as well as problems with misclassification for certain causes meant that the target list of causes for analysis was reduced to 34 for adults, 21 for children, and 10 for neonates, excluding stillbirths. To ensure strict independence for the validation of methods and assessment of comparative performance, 500 test-train datasets were created from the universe of cases, covering a range of cause-specific compositions.Conclusions: This unique, robust validation dataset will allow scholars to evaluate the performance of different verbal autopsy analytic methods as well as instrument design. This dataset can be used to inform the implementation of verbal autopsies to more reliably ascertain cause of death in national health information systems
