RESUMEN
Objective:To investigate the prognostic significance of anemia in elderly patients with stable coronary artery disease treated by percutaneous coronary intervention(PCI).Methods:In this retrospective cohort study, 180 patients with stable coronary artery disease aged ≥60 years undergone percutaneous coronary intervention and with complete clinical data, admitted to Nanjing Meishan Hospital between June 2016 and December 2017, were selected.Baseline clinical data of the patients were collected, including hemoglobin, C-reactive protein, lipids, fasting glucose, glycated hemoglobin, blood creatinine, and left ventricular ejection fraction on cardiac color ultrasound.The endpoints of the follow-up included major adverse cardiac events(MACE), such as all-cause death, non-fatal myocardial infarction, and non-fatal stroke.According to the hemoglobin level, participants were divided into an anemia group(n=32)and a non-anemia group(n=148). Clinical data of the two groups were compared, and the Kaplan-Meier method and multivariate analysis with the Cox regression method were used to evaluate the effect of anemia on the occurrence of MACE in elderly patients with stable coronary artery disease treated by PCI.Results:The median duration of the follow-up of the 180 patients was 702.5 days and MACE occurred in 27(15.0%). Compared with the non-anemia group, the anemia group had a higher age, C-reactive protein level and MACE ratio, lower levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol and the glomerular filtration rate, and higher proportions of patients with smoking history and patients with dyslipidemia( P<0.05). Kaplan-Meier curves suggested that the incidence of MACE in the anemia group was higher than that in the non-anemia group[37.5%(12/32) vs.10.1%(15/148), P<0.05]. Multivariate analysis with the Cox regression method showed that the risk of MACE in the anemia group was 2.91 times higher than that in the non-anemia group( HR=2.91, 95% CI: 1.13-7.48, P<0.05). Conclusions:Anemia is an independent predictor of MACE in elderly patients with stable coronary artery disease after PCI.
RESUMEN
@#Objective To investigate the clinical data of a family diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy(CADASIL) with isolated vertigo as the initial symptom. Methods The clinical manifestations,imaging findings,pathology,genetic testing results,and CADASIL scale score of a patient with CADASIL were summarized,and a family investigation was conducted. Results The proband of this case experienced recurrent isolated vertigo and gradually developed emotional disorder. Cranial magnetic resonance imaging(MRI) FLAIR revealed extensive subcortical white matter degeneration in both hemispheres,characteristic abnormal hyperintensity in bilateral temporal poles and external capsules,abnormal hyperintensity in bilateral brainstems,and multiple lacunar infarctions in bilateral corona radiata and basal ganglia. The score of CADASIL scale was 16 points. Skin biopsy showed the deposition of electron-dense granular osmiophilic material around vascular smooth muscle. Genetic testing identified a heterozygous mutation of c. 1163G>A(p. C388Y) in the NOTCH3 gene. The elder sister of the proband also had isolated vertigo and was found to have the same mutation by genetic testing. The father and uncle of the proband died of cerebral infarction,while the aunt of the proband suffered from severe dementia,and all of them had experienced dizziness in the early stage. Conclusion CADASIL has clinical heterogeneity and can manifest as isolated vertigo. Abnormal signals in temporal poles and external capsules on cranial MRI have an important value in the diagnosis of this disease,while pathological examination is required to make a confirmed diagnosis,and genetic testing can further clarify the diagnosis and perform screening of other family members.

Objective To investigate the changes and the correlation between the levels of plasma lysophosphalidic acid(LPA),acid phospholipid(AP),low density lipoprotein(LDL) and carotid artery atherosclerosis in patients with acute cerebral infarction(ACI).Methods The levels of plasma LPA,AP and LDL were examined in 67 ACI patients and 30 normal controls,the carotid arteries were investigated with B mode ultrosand.Results The levels of plasma LPA,AP and LDL were higher in ACI group than those in the normal control group(all P
