OBJECTIVETo determine the distribution of aortic arch and intra/extracranial cerebral arterial atherosclerosis in Chinese patients who had suffered acute ischemic strokes.
METHODSEighty-nine patients with acute ischemic strokes were included in this study. Transesophageal echocardiography (TEE) was used to evaluate potential sources of embolisms in the aortic arch and in the heart; duplex ultrasound was used for the carotid artery; and intracranial Doppler (TCD) imaging was used for the middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), and basilar artery (BA). An atherosclerotic lesion in the aortic arch was defined as normal (0); mild plaque (1); moderate plaque (2); and protruding plaque or mobile plaque (3). A lesion in the carotid artery was considered a plaque if the maximal carotid plaque thickness was 1.2 mm. TCD results were deemed abnormal if flow velocity was either greater or lower than normal, and, in the case of the MCA, if an asymmetry index above 21% was measured.
RESULTSOf the 89 patients, 52 (58.43%) patients showed evidence of aortic arch atherosclerosis (AAA), including 11 (12.36%) patients graded mild, 18 (20.22%) patients graded moderate, and 23 (25.84%) patients graded severe. Of the 23 patients with severe AAA, AAA was determined to be an important potential embolic source in 14 patients. Forty-nine (50.56%) patients had carotid arterial plaques (CAPs). The incidence of carotid plaques was higher among patients with AAA than among patients without AAA (71.15% vs 21.62%, OR = 3.291, 95% CI = 1.740 - 6.225, P < 0.001). TCD abnormalities affecting the MCA were found in 54 (60.67%) patients. Differences in incidence of TCD abnormalities between patients with AAA and without AAA (69.23% vs 48.65%) were not significant (OR = 1.423, 95% CI = 0.976 - 2.076, P = 0.05). There was a higher incidence of AAA in older, male patients with a history of diabetes and smoking.
CONCLUSIONSAAA is an important potential source of cerebral embolic strokes. The presence of carotid arterial plaques correlates with AAA incidence. Most of carotid artery lesion were plaques other than severe stenosis, it may be the character of carotid atherosclerosis of stroke patients. It appears that atherosclerosis does not mainly occur in the intracranial arteries in stroke patients as thought before. Aged, male, diabetes, and smoking are important risk factors to the AAA.

OBJECTIVESTo determine the relative value of transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in exploring the potential embolic source (PES) in heart and aortic arch and to study the clinical significance of aortic arch atherosclerosis (AAA).
METHODSForty-nine patients with cerebral embolism were included in this study. TEE and TTE were used to evaluate the potential source of emboli in aortic arch, heart and duplex in the carotid artery. An atherosclerotic lesion of the aortic arch was defined as normal, mild plaque, moderate plaque, and protruding plaque or mobile plaque.
RESULTSOf the 49 patients, 31 (63%) patients showed evidence of AAA: 7 (14.1%) patients were mild, 9 (18.4%) were moderate and 15 (30.6%) were severe. In those 15 patients, 11 had neither severe ICAA nor heart disease. Thirty-three patients had internal carotid arterial atherosclerosis (ICAA). The potential sources of embolization of heart and aortic arch is 48.98% by TEE, but only 18.4% by TTE; 9 patients had heart disease. Age and ICAA were significantly correlated with AAA.
CONCLUSIONAt present, TEE is a better method for exploring atherosclerotic lesions in the thoracic aorta. AAA is an important potential source of cerebral embolic stroke.

BACKGROUND:
Chromosomal abnormalities are important causes of ventriculomegaly (VM). In mild and isolated cases of fetal VM, obstetricians rarely give clear indications for pregnancy termination. We aimed to calculate the incidence of chromosomal abnormalities and incremental yield of chromosomal microarray analysis (CMA) in VM, providing more information on genetic counseling and prognostic evaluation for fetuses with VM.
METHODS:
The Chinese language databases Wanfang Data, China National Knowledge Infrastructure, and China Biomedical Literature Database (from January 1, 1991 to April 29, 2020) and English language databases PubMed, Embase, and Cochrane Library (from January 1, 1945 to April 29, 2020) were systematically searched for articles on fetal VM. Diagnostic criteria were based on ultrasonographic or magnetic resonance imaging (MRI) assessment of lateral ventricular atrium width: ≥10 to <15 mm for mild VM, and ≥15 mm for severe VM. Isolated VM was defined by the absence of structural abnormalities other than VM detected by ultrasonography or MRI. R software was used for the meta-analysis to determine the incidence of chromosomal abnormalities and incremental yield of CMA in VM, and the combined rate and 95% confidence interval (CI) were calculated.
RESULTS:
Twenty-three articles involving 1635 patients were included. The incidence of chromosomal abnormalities in VM was 9% (95% CI: 5%-12%) and incremental yield of CMA in VM was 11% (95% CI: 7%-16%). The incidences of chromosomal abnormalities in mild, severe, isolated, and non-isolated VM were 9% (95% CI: 4%-16%), 5% (95% CI: 1%-11%), 3% (95% CI: 1%-6%), and 13% (95% CI: 4%-25%), respectively.
CONCLUSIONS
Applying CMA in VM improved the detection rate of abnormalities. When VM is confirmed by ultrasound or MRI, obstetricians should recommend fetal karyotype analysis to exclude chromosomal abnormalities. Moreover, CMA should be recommended preferentially in pregnant women with fetal VM who are undergoing invasive prenatal diagnosis. CMA cannot completely replace chromosome karyotype analysis.

BACKGROUND:
China bears the biggest atrial fibrillation (AF) burden in the world. However, little is known about the incidence and predictors of AF. This study aimed to investigate the current incidence of AF and its electrocardiographic (ECG) predictors in general community individuals aged over 60 years in China.
METHODS:
This was a prospective cohort study, recruiting subjects who were aged over 60 years and underwent annual health checkups from April to July 2015 in four community health centers in Songjiang District, Shanghai, China. The subjects were then followed up from 2015 to 2019 annually. Data on sociodemographic characteristics, medical history, and the resting 12-lead ECG were collected. Kaplan-Meier curve was used for showing the trends in AF incidence and calculating the predictors of AF. Associations of ECG abnormalities and AF incidence were examined using Cox proportional hazard models.
RESULTS:
This study recruited 18,738 subjects, and 351 (1.87%) developed AF. The overall incidence rate of AF was 5.2/1000 person-years during an observation period of 67,704 person-years. Multivariable Cox regression analysis indicated age (hazard ratio [HR], 1.07; 95% confidence interval [CI]: 1.06-1.09; P < 0.001), male (HR, 1.30; 95% CI: 1.05-1.62; P = 0.018), a history of hypertension (HR, 1.55; 95% CI: 1.23-1.95; P < 0.001), a history of cardiac diseases (HR, 3.23; 95% CI: 2.34-4.45; P < 0.001), atrial premature complex (APC) (HR, 2.82; 95% CI: 2.17-3.68; P < 0.001), atrial flutter (HR, 18.68; 95% CI: 7.37-47.31; P < 0.001), junctional premature complex (JPC) (HR, 3.57; 95% CI: 1.59-8.02; P = 0.002), junctional rhythm (HR, 18.24; 95% CI: 5.83-57.07; P < 0.001), ventricular premature complex (VPC) (HR, 1.76; 95% CI: 1.13-2.75, P = 0.012), short PR interval (HR, 5.49; 95% CI: 1.36-22.19; P = 0.017), right atrial enlargement (HR, 6.22; 95% CI: 1.54-25.14; P = 0.010), and pacing rhythm (HR, 3.99; 95% CI: 1.57-10.14; P = 0.004) were independently associated with the incidence of AF.
CONCLUSIONS
The present incidence of AF was 5.2/1000 person-years in the studied population aged over 60 years in China. Among various ECG abnormalities, only APC, atrial flutter, JPC, junctional rhythm, short PR interval, VPC, right atrial enlargement, and pacing rhythm were independently associated with AF incidence.
