ABSTRACT
Objective:To explore the associations of malnutrition, sarcopenia and disability in older hospitalized patients.Methods:A retrospective study was conducted on 180 patients who were admitted to the department of geriatrics of our hospital from November 2015 to September 2020 and completed 1-year follow-up.Malnutrition and sarcopenia were diagnosed as the Global Leadership Initiative on Malnutrition(GLIM)criteria and the 2019 sarcopenia criteria issued by the Asian Working Group for Sarcopenia(AWGS2019).Disability was defined as a score of less than or equal to 95 on the Barthel Index(BI).At the end of the 1-year follow-up, a decrease of ≥5 points in the total BI score from baseline was defined as aggravation of the disability.Multivariate Logistic regression models were used to analyze the effects of malnutrition and sarcopenia on the occurrence and aggravation of the disability.Results:Among the 180 elderly patients, 27.2%(49/180)met the diagnosis of malnutrition and 39.4%(71/180)of sarcopenia, and 22.2%(40/180)of malnutrition and sarcopenia overlapped.The incidence of disability was 36.7%(66/180)at baseline and the incidence of an aggravation of disability was 31.7%(57/180)at 1-year follow-up.After adjustment for confounding factors, multivariate Logistic regression analysis showed that malnutrition( OR=3.70, 95% CI=1.27-10.80, P=0.017)and sarcopenia( OR=2.93, 95% CI=1.12-7.64, P=0.028)were risk factors for disability in elderly patients, and sarcopenia was a risk factor for aggravation of disability in elderly patients after a 1-year follow-up( OR=3.99, 95% CI=1.47-10.83, P=0.007). Conclusions:Malnutrition and sarcopenia are closely associated with the occurrence and development of disability in older hospitalized patients.
ABSTRACT
Objective:To explore the clinical value of peripheral remnant lipoproteins (RLP), low density lipoprotein cholesterol particle (LDL-P) and sdLDL particle (sdLDL-P) measurement in the diagnosis of carotid plaque, so as to provide practical basis for the accurate diagnosis of carotid plaque and the control of carotid plaque related cardiovascular and cerebrovascular diseases.Methods:People who underwent carotid plaque ultrasound examination in Xingtai Third Hospital , from January 2020 to June 2021 were selected as the research object. According to the ultrasound results, they were divided into carotid plaque group ( n=146) and control group without carotid plaque ( n=149). The fasting RLP, LDL-P and sdLDL-P of the two groups were measured by vertical auto profile (VAP) centrifugal separation phase, and the fasting TG and LDL-C were detected by routine mixed phase method. The indexes were compared between the two groups and the true positive rate, true negative rate, false positive rate and false negative rate of the diagnosis of carotid plaque were analyzed. The receiver operating characteristic curve of each test index was drawn, and AUC was used to evaluate the clinical diagnostic value of each test index for carotid plaque. Results:The levels of RLP, LDL-P and sdLDL-P in carotid plaque group were significantly higher than those in non-carotid plaque group ([1.07±0.36] mmol/L vs [0.59±0.17] mmol/L,[1 300±370] nmol/L vs [781±215] nmol/L,[435±139] nmol/L vs [156±59] nmol/L, all P<0.01). The true positive rate (78.08% [114/146],81.51% [119/146]) and true negative rate (84.56% [126/149], 86.58%[129/149]) of serum RLP and LDL-P for the diagnosis of carotid plaque were significantly higher than TG (58.90%[86/146], 43.62%[65/149]) and LDL-C (59.59% [87/146], 46.98% [70/149]), and the false positive rate (15.44% [23/149], 13.42% [20/149]) and false negative rate (21.92% [32/146], 18.49% [27/146]) were significantly lower than TG (56.38% [84/149], 41.10% [60/146]) and LDL-C (53.02% [79/149], 40.41% [59/146], all P<0.01). The AUC of the ROC curve of RLP (0.890), LDL-P (0.902) and sdLDL-P (0.973) for the diagnosis of carotid plaque was higher than TG (0.682) and LDL-C (0.712). The AUC of ROC curve of the RLP combined with sdLDL-P (0.977) for the diagnosis of carotid plaque was higher than the RLP and sdLDL-P (all P<0.01). Conclusion:The serum RLP, LDL-P and sdLDL-P can be used as indicators of carotid plaque, and their clinical diagnostic value are superior to TG and LDL-C; the combined diagnostic effect of lipoprotein subclass is better than that of single index alone.

ABSTRACT
Objective To investigate the relationship between fragmented QRS (fQRS) complexes and the severity of coronary artery lesions in elder patients with complex coronary artery lesions.Methods Two-hundred and one elder patients with complex coronary lesions undergone coronary angiography in Beijing Anzhen Hospital from January 2013 to July 2016 were enrolled.Based on the coronary lesions,patients were divided into the complex coronary lesions group and the simple coronary lesions group.The clinical features and coronary scores were compared between groups.Logistic regression analysis was used to evaluate the risk factors of complex coronary lesions.Results Compared with simple coronary lesions group,the complex coronary lesions group was associated with higher rate of fQRS (31.3％ vs.17.2％,x2 =9.68,P＜0.01),more number of fQRS leads [(1.0±1.5) vs.(0.5±0.8),t=-4.04,P＜0.01],longer duration of QRS [(87.2±10.7) ms vs.(84.1±8.9) ms,t=-3.09,P＜0.01].Moreover,patients with fQRS had a lower level of high density lipoprotein cholesterol (HDL-C) [M(Q25,Q75),0.9 (0.8,1.1) mmol/L vs.1.0 (0.9,1.2) mmol/L,t=-2.84,P＜0.01] and a higher Gensini score [40 (8-76) vs.22 (16-2),t=8.63,P＜0.01] compared with those without fQRS.Furthermore,Logistic regression analysis showed that HDL C (OR=0.346,95％CI:0.163 0.674,P＜0.05),fQRS (OR=2.215,95％ CI:1.381-3.725,P＜0.05) and the number of fQRS leads (OR=4.613,95％ CI:2.412-9.578,P＜0.05) were independent risk factors for patients with high Gensini score,and there was a positive correlation between fQRS and Gensini scores (=0.624,P＜0.01).Conclusions fQRS might be a noninvasive indicator of severity of coronary artery lesions for elder patients with complex coronary lesions.
ABSTRACT
To analyze the mortality risk of stroke in China by literature search.The mortality rate of stroke (age standardized) in China has declined in recent years.The mortality rate of stroke which increases with age is higher in rural areas than in urban areas,and is higher in men than in women in China.There are obvious regional differences and seasonal differences in the mortality of stroke in China.Different subtypes of stroke have different death characteristics.Low or high temperatures can increase the risk of mortality of stroke.With the change of epidemiological characteristics,the risk factors of mortality of stroke in China are also changing.Through the epidemiological study of stroke death,the mortality risk of stroke can be researched effectively,the epidemiological characteristics of stroke can be mastered,and the direction of prevention and treatment of stroke can be understood.Individualized and multi factor intervention for unhealthy lifestyle,unhealthy behavior and metabolic cardiovascular risk factors can promote the establishment of stroke prevention and control strategy in China.
ABSTRACT
Objective To investigate the correlation between red blood cell distribution width(RDW) and in-stent restenosis(ISR)in patients with coronary heart disease after PCI.Methods A total of nine hundred and seventy-eight patients with coronary heart disease treated in Beijing Anzhen Hospital,Capital Medical University with DES stent implantation from March 2015 to March 2016 were enrolled in the study.Among them,493 patients(50.41%)underwent coronary angiography in the hospital at 6-12 months after the operation.According to the results of the angiography,the patients were divided into two groups: the ISR group and the non-ISR group.The basic data of the patients,the laboratory indexes and the coronary interventional procedures record were collected to analyze the factors that could lead to in-stent restenosis.Results 51 cases(10.34%)in the ISR group and 442 cases(89.66%)in the non-ISR group.The baseline characteristics of the two groups were similar,and there was no significant difference in gender,age, body mass index,combined with hypertension,family history of coronary heart disease,long-term administration of statin and follow-up interval(P>0.05).The proportion of patients with diabetes was significantly higher than that of the non-ISR group(37.3% vs.22.6%,P=0.021);the smoking rate was significantly higher in the ISR group(52.9% vs.35.7%,P=0.016).In terms of laboratory examination,there were no significant differences between the two groups in blood lipid levels and WBC,RBC,Hb and PLT counts between the two groups(P>0.05).The levels of serum RDW(13.4(13.00,13.80)vs.12.7(12.40,13.10),P<0.01)and hs-CRP (3.15(2.32,4.63)vs.1.33(0.63,3.16),P<0.01)were significantly increased in the patients with ISR.The stent length was longer in the ISR group((21.87 ± 5.20)mm vs.(19.14 ± 4.87)mm,P<0.01),the stent diameter was smaller((2.87±0.38)mm vs.(3.09±0.36)mm,P<0.01),the number of cases with serial stents in ISR group was higher than that in non-ISR group(45.1 % Vs 30.8%,P=0.038).Multivariate logistic regression analysis showed that RDW(OR=2.396,95%CI 1.655-3.471;P<0.01),hs-CRP(OR=1.052, 95%CI:1.001-1.105;P=0.044),DM(OR=2.029,95%CI:1.004-4.100;P=0.049),smoking(OR=2.252,95%CI:1.060-4.783;P=0.035),stent length(OR=1.149,95%CI:1.072-1.230;P<0.01),stent diameter(OR=0.210,95%CI:0.079-0.558;P=0.002)and serial stents(OR=2.306,95%CI:1.162-4.575;P=0.017)were independent risk factors for in-stent restenosis.Conclusion Red blood cell distribution width is an independent predictor of in-stent restenosis after PCI in patients with coronary heart disease.Chronic inflammation and oxidative stress may be the most important pathogenesis of ISR.
ABSTRACT
Objective To analyze the value of plane QRS-T angle on prediction of malignant ventricular arrhythmia (MVA) occurred after emergency percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods The clinical data of 418 patients with STEMI who underwent PCI within 12 h of symptom onset were retrospectively analyzed, and the patients were divided into plane QRS-T angle ≤ 90° group (324 cases) and plane QRS-T angle>90° group (94 cases) according to the plane QRS-T angle after PCI. The clinical data were compared between 2 groups. Results Compared with patients in plane QRS-T angle ≤ 90° group, patients in plane QRS-T angle > 90° group was older: (67.4 ± 11.8) years vs. (63.6 ± 12.0) years, QTc interval was longer: (438.60 ± 34.97) ms vs. (425.24 ± 25.49) ms, rate of left ventricular ejection fraction (LVEF) 90° was an independent risk factor of MVA after PCI in STEMI patients (OR = 9.640, P =0.001), and using of beta-blockers was a protective factor (OR = 0.266, P = 0.028). Conclusions Plane QRS-T angle>90° is an independent risk factor of MVA after PCI in STEMI patients, while the use of beta-blockers is a protective factor. Paients with STEMI after PCI should be alert to the occurrence of MVA in the condition of plane QRS-T angle>90° and not taking beta-blockers.
ABSTRACT
Objective To evaluate the efficiency of rotational atherectomy (RA) with drug-eluting stents (DES) by intravascular ultrasound (IVUS) for elderly patients with heavily calcified lesions. Methods Thirteen patients aged above 70 years with heavily calcified coronary artery having underwent the treatment of RA and DES by IVUS were enrolled. The levels of troponin T, creatine kinase isozyme-MB and creatinine were detected before and after operation.The levels of minimus lumen diameter, diameter stenosis rate, effective area of the lumen before and after operation were compared. The immediate success rate was evaluated and the follow-up results were recorded. Results Thirteen patients in accordance with angiography and IVUS examination were confirmed as severe calcification. The levels of troponin T, creatine kinase isozyme-MB and creatinine detected before and after operation had no significantly differences (P>0.05). The levels of minimus lumen diameter, diameter stenosis rate and effective area of the lumen before and after operation had significant differences:(2.06 ± 0.38) mm vs. (3.98 ± 0.76) mm, (73.26 ± 7.02)%vs. (17.00 ± 3.34)%, (4.53 ± 1.50) mm2 vs. (12.54 ± 6.19) mm2, P<0.01. The rate of left anterior descending artery, circumflex artery and right coronary artery calcification was 10/13, 0 and 1/13. All patients′operation was successful. Followed up for (14.6 ± 3.4) months, no patients had angina and myocardial infarction, or required target vessel revascularization. Conclusions RA with DES by IVUS can be safely used in elderly patients with severely calcified coronary artery disease, and can improve the success rate of intervention operation.

ABSTRACT
Objective To assess the value of hemofiltration in the prevention of contrast induced nephropathy(CIN) post percutaneous coronary intervention(PCI) in severe chronic kidney disease stages(CKD) patients. Methods We evaluated 30 CKD patients who underwent PCI followed by bedside hemofiltration. We measured serum creatinine levels before PCI, 24 hours, 72 hours, and one week after PCI, and calculated creatinine clearance(CrCl) according to Cockcroft and Gault equation.We observed the incidence of CIN, and the short term clinical efficacy of hemofiltralion. Results The average age of the 30 patients was (72.87 ± 8.71) years old, with 21 (70%) male patients. The stages of CKD among the patients included CKD 3 (3 patients, 10%), CKD 4 (20 patients, 66.7%) and CKD 5 (7 patients, 23.3%). The average duration of hemofiltration was (7.5±4.1) hours. Serum creatinine before PCI, 24 hours, 72 hours and 1 week after PCI was (498.7±143.7)μmol/L, (353.2±128.0)μmol/L, (450.0±132.2)μmol/L, (488.0±145.7)μmol/L respectively,and CrCl was (20.3±10.2) ml/min, (36.5±14.3) ml/min, (28.3±10.4) ml/min, (21.0±10.3) ml/min respectively. There was no CIN. Mean follow-up was (3.1 ± 2.6) months. There was no new cardiovascular events, and no new patients need to rely on long term hemodialysis. Conclusions For patients with severe renal insufficiency, hemofiltration may reduce the incidence of CIN, It is an alternative preventive measures to prevent CIN.
ABSTRACT
<p><b>BACKGROUND</b>A number of studies have demonstrated the rates of overall and aneurysm-related mortality and morbidity in Western populations. The cardiovascular risk factors influencing postoperative outcome have been also reported. Until recently, little has been known about the prognosis in this patient cohort in the Chinese population. We evaluated the independent predictors of mortality and morbidity in abdominal aortic aneurysm (AAA) patients undergoing elective surgical treatment and emphasized whether the coronary artery revascularization could have any effect on the overall mortality and morbidity in patients following the current guideline recommendation.</p><p><b>METHODS</b>A total of 386 patients (174 women) undergoing surgery in Beijing Anzhen Hospital from January 2008 to June 2010 were enrolled (mean age (70.6±10.5) years). Kaplan-Meier curves were constructed to compare the mortality and morbidity of AAA patients with coronary artery revascularization and those without. A Cox proportional hazards model was constructed to identify clinical factors associated with two-year outcomes. The primary outcomes were death from any cause, the pre-specified morbidity was re-hospitalization for pulmonary conditions, congestive heart failure, angina, ischemic/hemorrhagic stroke.</p><p><b>RESULTS</b>During the two-year follow-up, 34 patients died and 65 experienced re-hospitalization with pulmonary conditions, congestive heart failure, angina, or ischemic/hemorrhagic stroke. Kaplan-Meier survival analysis showed that the AAA patients with cardiac revascularization had no higher incidence of overall mortality and major morbidity than those without (log-rank test P = 0.35 and P = 0.40, respectively). Cox proportional hazards regression analysis showed that level of lowdensity lipoprotein (HR, 4.06; 95% CI: 1.19-18.7, P = 0.027) and AAA size (HR, 2.18; 95% CI: 1.28-11.65, P = 0.036) were independently associated with the incidence of overall mortality. Long-term use of angiotensin converting enzyme inhibitors, statins, AAA size and systolic blood pressure were independent predictors of the secondary pre-specified outcomes.</p><p><b>CONCLUSIONS</b>Coronary artery revascularization following the guideline recommendations did not increase the mortality and morbidity of Chinese with AAA who were undergoing repair. Absence of angiotensin converting enzyme inhibitors and statins, AAA size, and systolic blood pressure were powerful predictors of the clinical events.</p>

ABSTRACT
ObjectiveTo investigate the independent risk factors of 30-day mortality of nontraumatic acute chest pain in emergency department so as to get non - traumatic acute chest pain risk score,MethodsThe clinical data of 532 patients with non - traumatic acute chest pain were reviewed.The independent risk factors of 30 - day mortality were identified after analysis of medical history,symptom and sign,laboratory findings by uuivariate analysis and logistic regression.Non- traumatic acute chest pain risk score was made as per the odds ratios of these risk factors. ResultsThe average age of the patients was (55.7 + 12.7 ) years,and 45 patients ( 8.4％ ) died after 30 days.In patients with non - traumatic acute chest pain,history of hypertension (OR:4.28; 95％ CI:1.59-11.55 ),prolonged chest pain (OR:1.1; 95％ CI:1.05-1.15),dyspnea (OR:6.61; 95％CI:2.40-18.10) and tachycardia (OR:1.02; 95％CI:1.00-1.04),high leucocyte count (OR:1.18; 95％CI:1.06-1.31) and D - Dimer ( OR:1.002; 95％ CI:1.001-1.002 ) predicted 30 - day mortality independently,whereas chest pain relieved by medicine (OR:0. 15; 95％ CI:0.04-0.65),high blood oxygen saturation (SaO2) (OR:0.89; 95％CI:0.83-0.98) and normal hematocrit (OR:0.92; 95％CI:0.86-0.99) were good markers to predict optimistic prognosis.Non - traumatic acute chest pain risk score was higher in 30 - day dead group than those in survival group significantly ( P ＜ 0.01 ),and mortality was significantly different between groups with various risk stratification (P ＜ 0. 01 ).Conclusions Clinical physician can predict 30 - day mortality and evaluate prognosis in patients with acute chest pain by using non - traumatic acute chest pain risk score quickly and effectively.
ABSTRACT
G-protein-coupled receptor kinases (GRKs) are a family of serine/threonine protein kinases. The investigators pay much attention to the roles of GRKs in the signal transduction through G-protein-coupled receptors (GPCRs) with arrestin ever since a long time ago. Due to the physiological and pathological observations with the methods of deletion or overexpression, GRKs are considered as new drug targets. The kinases play a role in the pathogenesis of hypertension and cell migration through GPCRs and Hedgehog signaling pathways. As the development of research techniques, especially bioluminescence resonance energy transfer (BRET) and fluorescence resonance energy transfer (FRET), the special mechanism of GRKs for GPCRs is more evident. In this review, we discuss the recent achievement in the roles of GRKs signaling and the related newest research techniques.
ABSTRACT
Objective: To explore the efficacy of esmolol on cardiac ischemia in patients with serious coronary lesions who are not candidates for coronary revascularizations. Methods: Fifty seven aged patients (34 male) with serious coronary artery disease not candidates for coronary revascularizations were included. All patients had classical angina involved in cardiac ischemia, and definitely ischemic ST-segment depressions in surface electrocardiogram, however which were not relieved by routine treatment including intravenous nitrate or even morphine. All patients received loading dose injection and continuously intravenous infusion of Esmolol, and the baseline characteristics before treatment and the effects at 4 hours after infusion of Esmolol were carefully recorded. Results: After infusion of Esmolol, the ischemia-related symptoms of 41 patients completely relieved, and their ST depressions recovered to the baseline accompanied with significant reduction in blood pressure and heart rate (P＜0.0001 all) within (66±23) min. Moreover, nine patients were observed that their ischemia-related symptoms were relieved and ST alteration recovered partially (P＜0.0001 both) at four h after continuous infusion of esmolol. Conclusion: Esmolol is effective to relieve the serious cardiac ischemia-related symptoms and ST-T alteration of ECG in patients with serious coronary lesions.
