The data with respect to stable coronary artery disease (SCAD) are mainly confined to main vessel disease. However, there is a lack of information and long-term outcomes regarding isolated side branch disease. This study aimed to evaluate long-term major adverse cardiac and cerebrovascular events (MACCEs) in patients with isolated side branch coronary artery disease (CAD). A total of 437 patients with isolated side branch SCAD were included. After a median follow-up of 38 months, the overall MACCE and all-cause mortality rates were 14.6% and 5.9%, respectively. Among angiographic features, 68.2% of patients had diagonal artery and 82.2% had ostial lesions. In 28.8% of patients, the vessel diameter was ≥2.75 mm. According to the American College of Cardiology lesion classification, 84.2% of patients had either class B or C lesions. Age, ostial lesions, glycated hemoglobin A1c, and neutrophil levels were independent predictors of MACCE. On the other hand, side branch location, vessel diameter, and lesion complexity did not affect outcomes. Clinical risk factors seem to have a greater impact on MACCE rather than lesion morphology. Therefore, the treatment of clinical risk factors is of paramount importance in these patients.

Abstract Background The risk of sudden cardiac death (SCD) is known to be dynamic. However, the accuracy of a dynamic SCD prediction is unknown. We aimed to measure the dynamic predictive accuracy of ECG biomarkers of SCD and competing non-sudden cardiac death (non-SCD). Methods Atherosclerosis Risk In Community study participants with analyzable ECGs in sinus rhythm were included (n = 15,716; 55% female, 73% white, age 54.2 ± 5.8 y). ECGs of 5 follow-up visits were analyzed. Global electrical heterogeneity and traditional ECG metrics (heart rate, QRS, QTc) were measured. Adjudicated SCD was the primary outcome; non-SCD was the competing outcome. Time-dependent area under the receiver operating characteristic curve (ROC(t) AUC) analysis was performed to assess the prediction accuracy of a continuous biomarker in a period of 3,6,9 months, and 1,2,3,5,10, and 15 years using a survival analysis framework. Reclassification improvement as compared to clinical risk factors (age, sex, race, diabetes, hypertension, coronary heart disease, stroke) was measured. Results Over a median 24.4 y follow-up, there were 577 SCDs (incidence 1.76 (95%CI 1.63–1.91)/1000 person-years), and 829 non-SCDs [2.55 (95%CI 2.37–2.71)]. No ECG biomarkers predicted SCD within 3 months after ECG recording. Within 6 months, spatial ventricular gradient (SVG) elevation predicted SCD (AUC 0.706; 95%CI 0.526–0.886), but not a non-SCD (AUC 0.527; 95%CI 0.303–0.75). SVG elevation more accurately predicted SCD if the ECG was recorded 6 months before SCD (AUC 0.706; 95%CI 0.526–0.886) than 2 years before SCD (AUC 0.608; 95%CI 0.515–0.701). Within the first 3 months after ECG recording, only SVG azimuth improved reclassification of the risk beyond clinical risk factors: 18% of SCD events were reclassified from low or intermediate risk to a high-risk category. QRS-T angle was the strongest long-term predictor of SCD (AUC 0.710; 95%CI 0.668–0.753 for ECG recorded within 10 years before SCD). Conclusion Short-term and long-term predictive accuracy of ECG biomarkers of SCD differed, reflecting differences in transient vs. persistent SCD substrates. The dynamic predictive accuracy of ECG biomarkers should be considered for competing SCD risk scores. The distinction between markers predicting short-term and long-term events may represent the difference between markers heralding SCD (triggers or transient substrates) versus markers identifying persistent substrate.

Abstract Background We developed and validated laboratory test–based risk scores (i.e., lab risk scores) to reclassify mortality risk among patients undergoing their first coronary catheterization. Methods Patients were catheterized between 2009 and 2015 in Calgary, Alberta, Canada (n = 14 135, derivation cohort), and in Edmonton, Alberta, Canada (n = 12 143, validation cohort). Logistic regression with group LASSO (least absolute shrinkage and selection operator) penalty was used to select quintiles of the last laboratory tests (red blood cell count, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, mean corpuscular volume, red cell distribution width, platelet count, total white blood cell count, plasma sodium, potassium, chloride, CO2, international normalized ratio, estimated glomerular filtration rate) performed <30 days before catheterization and by age and sex that were significantly associated with death ≤60  and >60 days after catheterization. Follow-up was until 2016. Risk scores were developed from significant tests, internally validated in Calgary among bootstrap samples and externally validated in Edmonton after recalibration using coefficients developed in Calgary. Interaction tests were performed, and net reclassification improvement vs conventional demographic and clinical risk factors was determined. Results Lab risk scores were strongly associated with mortality (29–40× for top vs bottom quintile, P for trends <0.01), had good discrimination and were well calibrated in Calgary (C = 0.80–0.85, slope = 0.99–1.01) and Edmonton (C = 0.80–0.82; slope = 1.02–1.05)—similar to demographic and clinical risk factors alone. Associations were attenuated by several comorbidities; however, scores appropriately reclassified 11%–20% of deaths (both follow-up periods) and 6%–9% of survivors (>60 days) after catheterization vs demographic and clinical risk factors. Conclusions In 2 populations of patients undergoing their first coronary catheterization, risk scores based on simple laboratory tests were as powerful as a combination of demographic and clinical risk factors in predicting mortality. Lab risk scores should be used for patients undergoing coronary catheterization.

Background: Previous studies have examined individual risk factors in relation to peripheral arterial disease (PAD) but the combined effects of these factors are largely unknown. We investigated the degree to which clinical risk factors may explain the risk of PAD among men. Methods: We prospectively followed 45,596 men from the Health Professional Follow-up Study without a history of cardiovascular disease at baseline during a 22-year period (1986–2008). We defined four clinical risk factors - smoking, history of type 2 diabetes, hypertension, and hypercholesterolemia - that were updated biennially during follow-up. Cox proportional hazard models were used to compare PAD risk across individual and joint risk factors. Results: During 874,769 person-years of follow-up, 497 confirmed PAD cases occurred. All four clinical risk factors were significantly and independently associated with a higher risk of PAD after multivariate adjustment (Figure). Risk of PAD more than doubled (hazard ratio: 2.14; 95% confidence interval [95% CI]: 1.95–2.35) for each additional risk factor compared with the group free of risk factors. Men without any of the four risk factors had a relative risk of PAD of 0.19 compared with all other men (95% CI: 0.11–0.31). In 96.8% (95% CI: 95.2–98.3%) of the PAD cases, at least one of the four risk factors was present. Overall, 8 out of 10 cases of PAD appeared to be attributable to these four conventional risk factors. Conclusion: The great majority of PAD can be explained by four conventional risk factors. Figure legend: Hazard ratios for incident peripheral arterial disease (PAD) according to individual and joint risk factors. Hazard ratios are adjusted for age, height, aspirin use, family history of myocardial infarction before age 60 y, geographical region, body mass index, physical activity, alcohol consumption (and each of the other three binary clinical risk factors in the individual risk factor analyses).

ObjectiveThe association between ulcerative colitis (UC) and colorectal cancer (CRC) is widely accepted, although attenuated risk has been reported in recent years. Colonoscopic surveillance is recommended with intervals based on established clinical risk factors. Nevertheless, a significant number of patients develop interval cancers, indicating the need of improved individualised assessment. In the present study, we evaluated clinical risk factors associated with CRC during a prescheduled follow-up 20 years after diagnosis, the IBSEN study.DesignA population-based inception cohort of patients diagnosed with inflammatory bowel disease from 1 January 1990 until 31 December 1993, prospectively followed at 1, 5, 10 and 20 years after diagnosis. A total of 517 patients with UC were included; 264 (51 %) men; median age at inclusion 37.4 years (4–88).ResultsThe overall incidence of CRC was 1.6% (8/517) at a 20-year follow-up. The total lifetime risk of CRC prior to or after UC diagnosis was 2.3%. (12/517). Patients older than 70 years at diagnosis had a 15-fold higher risk of CRC compared with those diagnosed when younger than 40 years, with HR 15.68 (95% CI: 1.31 to 187.92). Neither sex, first-degree relative with CRC, extent of colitis nor primary sclerosing cholangitis affected the risk of CRC.ConclusionThe risk of CRC in UC was low and comparable with the risk of CRC in the background population of Norway.

ABSTRACTEfforts to identify clinical risk factors for complete suicide through the follow-up of depressed patients have yielded relatively few robust predictors. Those identified by at least three studies are (in order of decreasing frequency) suicidal plans/attempts, male sex, being single or living alone, inpatient status, and hopelessness. Because the best established of these predictors has only modest sensitivity and specificity, the need for other robust tools is clear. A rich body of research has identified two biological risk factors for suicide in depressive disorder: hypothalamicpituitary-adrenal axis hyperactivity and deficits in serotonin function. Moreover, there is now considerable evidence that the dexamethasone suppression test and measures of serum cholesterol concentrations, respectively, may provide a clinically useful reflection of these two mechanisms. Observations that these measures appear to be additive, both with each other and with other clinical risk factors, indicate that a substantial improvement in the clinician's ability to assess suicide risk is possible.

Abstract Introduction: Sickle cell disease (SCD) is characterized by chronic hemolytic anemia and chronic inflammation resulting in endothelial damage, neutrophil and platelet activation, enhanced cell adhesion and coagulation activation. Due to these conditions, sickle cell disease is considered to be a procoagulant condition. However, limited studies have evaluated the incidence of thrombosis in sickle cell disease and clinical risk factors for thrombosis are not clear. Here we present a retrospective cohort study to determine the incidence of VTE in a well characterized cohort of adult sickle cell patients. The aim of the study was to assess the cumulative incidence of venous thromboembolic events in patients with SCD and to relate this complication with clinical risk factors, genotype, organ damage and laboratory parameters. Methods: All patients with SCD (HbSS, HbSC, HbSβ0 thalassemia, HbSβ+ thalassemia) of ≥ 18 years in a tertiary clinic for SCD at the Amsterdam University Medical Center in the Netherlands were eligible for the study. Patients with a history of prior VTE or VTE or VTE at first presentation were excluded. Patients were divided into a subgroups with a severe genotype (HbSS/HbSβ0 thalassemia) and a mild genotype (HbSC/HbSβ+ thalassemia). Hospital electronic records were analyzed for occurrences of deep vein thrombosis (DVT) or pulmonary embolism (PE) objectified with diagnostic tests (ultrasound, high probability ventilation/perfusion scan or CT angiography). All sickle cell related complications, organ damage and clinical risk factors at the time of the VTE were scored. General laboratory parameters were gathered from patient records in steady state condition. Results: In total 228 patients were included in the study with a mean age of 24 ± 10 years at the start of follow up years and a total follow up of 1548 patient years. Median follow up was 5 years (IQR 2-10). Twenty-one patients suffered one or more VTE episodes (9.2%), resulting in an incidence rate in the entire cohort of 13.6 VTE events per 1000 patient years (95%Cl 9.7-22.0). We recorded 8 recurrences of VTE in 5 patients (1 patient suffered two VTE recurrences, and 1 patient had three VTE recurrences) with a median time to recurrence of 3 years (IQR 1-4). Mean age at the time of first VTE was 29 years. The first VTE episodes consisted of an isolated DVT of the leg/arm in 8/21 patients, an isolated PE in 10/21 patients, and a combined DVT and PE in 3/21 patients. Of these first VTE episodes 9/21 (43%) were found to be idiopathic, 5/21 (24%) occurred during oral contraceptive use and 7/21 (33%) were provoked by recent surgical procedure/hospital admission/central venous catheter. VTE was significantly associated with a previous history of acute chest syndrome (ACS) (OR 10.6 [3.3 - 46.6] P<.001), avascular necrosis (AVN) (OR 5.6 [2.1 - 15.0] P <.001) and a ferritin level >1000 μg/L (OR 3.8 [1.4 - 10.2] P=0.023). No significant association with other forms of organ damage was found. Patients with a severe genotype had a higher incidence of VTE than patients with a mild genotype (11.4% versus 5.6%). In the severe genotype subgroup, lower median HbF levels correlated with an increased risk of VTE (P <.005). Ten patients died during follow-up at a mean age of 40 ± 16 years. Conclusion: Sickle cell patients have a remarkably high incidence rate of VTE (13.6 events per 1000 patients years) with a high recurrence rate (23.8%). This confirms the hypercoagulable state of patients with SCD. Sickle cell related complications like ACS and AVN were associated with VTE. Given the high incidence and recurrence rate, awareness for VTE in SCD patients is warranted and long term anticoagulation may be indicated. Disclosures No relevant conflicts of interest to declare.
