Project description:Chronic risk factors for pseudoaneurysm (PSA) or penetrating aortic ulcer (PAU) have not been fully clarified. This study aims to evaluate the association of aortic calcification with PSA or PAU of different etiologies. Totally 77 pseudoaneurysms, 80 PAU, and 160 healthy controls (HCs) were retrospectively included, of which 30 were infected, 34 were immunological, and 93 were atherosclerotic etiologies. The aortic calcification status, position of aortic tears/ulcers, and risk factors for disease or acute aortic syndrome (AAS) were identified. Atherosclerotic patients aged more than 65 and infective patients aged more than 60 had significantly higher calcification scores. The immunological group had a lower level of calcification in the infrarenal aorta. For patients of infective or atherosclerotic etiology, 60% (18/30) and 60.22% (56/93) of the tears/ulcers occurred at the aortic parts with the highest level of calcification. Patients with longitudinal calcification exceeding 1/3 of the aortic arch had an increased risk of acquiring diseases (OR = 13.231). The presence of longitudinal calcification of the descending aorta or cross-sectional calcification of the infrarenal aorta increased the risks of acquiring diseases (OR = 8.484 and 8.804). After adjusting for age, longitudinal calcification of the descending aorta exceeding 1/3 length was found to be associated with AAS (OR = 4.662). Tears/ulcers of pseudoaneurysm and PAU were both generally found at the part of the aorta with most calcification. Distinct aorta calcification characteristics were observed for lesions of different etiologies. Longitudinal thoracic and cross-sectional infrarenal abdominal aortic calcification increased the risk of acquiring diseases, and descending aortic calcification was associated with symptomatic patients.

Project description:ObjectiveThe nonaortic cardiovascular morbidity and mortality of patients with aortic dissection (AD), intramural hematoma (IMH), and penetrating aortic ulcer (PAU) is unknown. We aimed to define the rates of cardiovascular (CV) events in a cohort of patients with newly diagnosed AD, IMH, and PAU.MethodsWe performed a retrospective review of all Olmsted County, Minnesota, residents diagnosed with AD, IMH, and PAU from 1995 to 2015. The primary outcome was nonaortic CV death. The secondary outcome was a first-time nonfatal CV event (myocardial infarction, heart failure [HF], or stroke). The outcomes were compared with age- and sex-matched population referents using Cox proportional hazards regression, with adjustment for comorbidities.ResultsA total of 133 patients (77 with AD, 21 with IMH, 35 with PAU; 57% male) with a mean age of 71.8 ± 14.1 years were identified. The median follow-up was 10 years. Compared with the population referents, the patients with AD/IMH/PAU had an increased risk of CV death (adjusted hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.4-4.2; P = .003) and an increased risk of any first-time nonfatal CV event (adjusted HR, 3.0; 95% CI, 1.9-4.8; P < .001), mainly resulting from an increased risk of first-time HF (adjusted HR, 2.7; 95% CI, 1.7-4.3; P < .001). When excluding events within 14 days of the diagnosis, the patients with AD/IMH/PAU remained at increased risk of CV death (adjusted HR, 2.6; 95% CI, 1.4-4.7; P = .002), any first-time nonfatal CV event (adjusted HR, 2.6; 95% CI, 1.5-4.4, P <.001), and first-time HF (adjusted HR 2.5, 95% CI 1.5-4.3; P < .001).ConclusionsCompared with the population referents, the patients with AD/IMH/PAU had a two- to threefold risk of nonaortic CV death, any first-time nonfatal CV event, and first-time HF. These data implicate the need for long-term cardiovascular management for patients with AD/IMH/PAU.

Project description:BackgroundCoronary artery spasm (CAS) is a pathological condition resulting from transient functional narrowing of the coronary arteries leading to myocardial ischaemia and in some rare cases even to sudden cardiac arrest (SCA). The most important preventable risk factor is use of tobacco, whereas possible precipitating factors include some medications and psychological stress.Case summaryA 32-year-old woman was hospitalized with burning chest pain. The immediate investigations revealed the diagnosis of non-ST-segment elevation myocardial infarction, because of ST elevations in one single lead and increased high-sensitivity troponin. Due to ongoing chest pain and a severe impaired left ventricular ejection fraction (LVEF) of 30% with apical akinesia, a prompt coronary angiography (CAG) was scheduled. After aspirin administration, she developed anaphylaxis with pulseless electrical activity (PEA). She could be resuscitated successfully. CAG revealed multi-vessel CAS for which she received calcium channel blockers. Five days after, she suffered from a second SCA due to ventricular fibrillation and was resuscitated again. Repeated CAG showed no critical coronary artery occlusion. LVEF improved progressively during hospitalization. Drug therapy was increased, and a subcutaneous implantable cardioverter defibrillator (ICD) was implanted for secondary prevention.DiscussionCAS may in some instances lead to SCA, especially in case of multi-vessel involvement. Allergic and anaphylactic events can trigger CAS, which are frequently underestimated. Regardless of the cause, cornerstone of CAS prophylaxes remains optimal medical therapy as in the avoidance of predisposing risk factors. In case of life-threatening arrhythmia, the implantation of an ICD should be considered.

Project description:MicroRNAs (miRNAs) have regulatory functions in organs critical in resuscitation from sudden cardiac arrest due to ventricular fibrillation (VF-SCA); therefore, circulating miRNAs may be markers of VF-SCA outcome.We measured candidate miRNAs (N=45) in plasma using qRT-PCR among participants of a population-based VF-SCA study. Participants were randomly selected cases who died in the field (DF, n=15), died in hospital (DH, n=15), or survived to discharge (DC, n=15), and, age-, sex-, and race-matched controls (n=15). MiRNA levels were compared using ANOVA, t-tests, and fold-changes.Mean age of groups ranged from 66.9 to 69.7. Most participants were male (53-67%) and white (67%). Comparing cases to controls, plasma levels of 17 miRNAs expressed in heart, brain, liver, and other tissues (including miR-29c, -34a, -122, -145, -200a, -210, -499-5p, and -663b) were higher and three non-specific miRNAs lower (miR-221, -330-3p, and -9-5p). Among DH or DC compared with DF cases, levels of two miRNAs (liver-specific miR-122 and non-specific miR-205) were higher and two heart-specific miRNAs (miR-208b and -499-5p) lower. Among DC vs. DF cases, levels of three miRNAs (miR-122, and non-specific miR-200a and -205) were higher and four heart-specific miRNAs (miR-133a, -133b, -208b, and -499-5p) lower. Among DC vs. DH cases, levels of two non-specific miRNAs (miR-135a and -9-3p) were lower.Circulating miRNAs expressed in heart, brain, and other tissues differ between VF-SCA cases and controls and are related to resuscitation outcomes. Measurement of miRNAs may clarify mechanisms underlying resuscitation, improve prognostication, and guide development of therapies. Results require replication.

Project description:ObjectiveEthnic differences in sudden cardiac arrest resuscitation have not been fully explored and studies have yielded inconsistent results. We examined the association of ethnicity with factors affecting sudden cardiac arrest outcomes.MethodsRetrospective cohort study of 3551 white, 440 black and 297 Asian sudden cardiac arrest cases in Seattle and King County, Washington, USA.ResultsCompared with whites, blacks and Asians were younger, had lower socioeconomic status and were more likely to have diabetes, hypertension and end-stage renal disease (all p<0.001). Blacks and Asians were less likely to have a witnessed arrest (whites 57.6%, blacks 52.1%, Asians 46.1%, p<0.001) or receive bystander cardiopulmonary resuscitation (whites 50.9%, blacks 41.4%, Asians 47.1%, p=0.001), but had shorter average emergency medical services response time (mean in minutes: whites 5.18, blacks 4.75, Asians 4.85, p<0.001). Compared with whites, blacks were more likely to be found in pulseless electrical activity (blacks 20.9% vs whites 16.6%, p<0.001), and Asians were more likely to be found in asystole (Asians 41.1% vs whites 30.0%, p<0.001). One of the strongest predictors of resuscitation outcomes was initial cardiac rhythm with 25% of ventricular fibrillation, 4% of patients with pulseless electrical activity and 1% of patients with asystole surviving to hospital discharge (adjusted OR of resuscitation in pulseless electrical activity compared with ventricular fibrillation: 0.30, 95% CI 0.24 to 0.34, p<0.001, adjusted OR of resuscitation in asystole relative to ventricular fibrillation 0.21, 95% CI 0.17 to 0.26, p<0.001). Survival to hospital discharge was similar across all three ethnicities.ConclusionsWhile there were differences in some prognostic characteristics between blacks, whites and Asians, we did not detect a significant difference in survival following sudden cardiac arrest between the three ethnic groups. There was, however, an ethnic difference in presenting rhythm, with pulseless electrical activity more prevalent in blacks and asystole more prevalent in Asians.

Project description:Studies of miRNA profiling to predict outcome in cardiac arrest patients treated with therapeutic hypothermia (TH) Venous blood was collected in citrated tubes prior discharge. Plasma was harvested by centrifugation and stored at -80°C until assayed. Identical volumes of plasma from the 14 patients of a group (cerebral performance category (CPC): 1-2 or CPC: 3-5) were pooled to reach a final volume of 400µL for each group. The two pools were processed conjointly. Total RNA was extracted using miRVana isolation kit (Applied Biosystems), dephosphorylated and labeled using miRNA Complete Labeling and hybridization kit (Agilent). Hybridization was performed on miRNA Human Microarray Release 12.0 slides (Agilent). 4 arrays per pool were hybridized. Scanning was achieved with the Genepix 4000B Scanner (Molecular Devices, Sunnyvale, USA). Raw data were acquired with the Genepix Pro software (Molecular Devices).
