Abstract

OBJECTIVE: To determine whether a decreased incidence of nonreactive nonstress tests (NSTs) in antepartum testing was attributable to the addition of fetal movement detection to the standard NST. METHODS: Monitors with standard fetal heart rate recording capabilities were used, as were new monitors producing a Doppler-detected recording of fetal movement (NST-fetal movement). Cross-sectional retrospective analysis of NST results was carried out by chi 2. RESULTS: Comparison of the 10-month period before fetal movement detection to the 10 months including NST-fetal movement monitoring showed a significant decrease in nonreactive NSTs from 5.7% to 3.3% (chi 2 = 61.7, 95% confidence interval [CI] 0.97-0.98). This reduction in nonreactive tests disappeared (3.3% to 5.1%) when the NST-fetal movement-capable monitors were no longer available (chi 2 = 24.2, 95% CI 1.01-1.03). CONCLUSIONS: Nonreactive NSTs decreased by 58% with the introduction of fetal movement monitoring in our antepartum testing center and increased when the NST-fetal movement-capable monitors were removed. A reduced incidence of nonreactive NSTs associated with NST-Doppler-detected fetal movements should effect a savings in both time and resources.

Dichotomous pattern of coronary atherosclerosis 1 to 9 years after transplantation: insights from systematic intravascular ultrasound imaging.

OBJECTIVE: The aim of this study was to evaluate the extent and distribution of coronary atherosclerosis after transplantation. BACKGROUND: Transplant coronary artery disease is an important cause of death after cardiac transplantation. Unlike coronary angiography, intravascular ultrasound is a sensitive tool for detection and quantitation of this disease. METHODS: We performed intravascular ultrasound imaging in 132 (106 men, 50 +/- 10 years) patients, 1 to 9 years after transplantation using a 30-MHz ultrasound catheter. RESULTS: All three coronary arteries were visualized in 49, two in 62 and one in 21 patients. Of the 1,188 coronary artery segments, 706 were imaged (74% proximal, 64% mid- and 40% distal). At least one site with atherosclerosis (intimal thickness > or = to 0.5 mm) was found in 83% of patients. Atherosclerosis was noted in 64% of proximal, 43% of mid- and 26% of distal segments. Disease was diffuse in 48% and focal in 52%, circumferential in 66% and noncircumferential in 34%. Focal atherosclerosis was more common in proximal (59%) than mid- (48%) and distal segments (27%) (p=0.001). Noncircumferential plaques were more common in the proximal (42%) than mid- (28%) and distal segments (12%) (p=0.001). This pattern of focal and noncircumferential disease proximally, diffuse and circumferential disease distally, was observed irrespective of the time from transplantation. CONCLUSION: Atherosclerosis was detected in more than 80% of patients, with proximal segments most frequently involved. Diffuse and circumferential atherosclerosis was more common in mid- and distal segments. However, focal and noncircumferential involvement was more frequent proximally, a similar pattern to native atherosclerosis. These findings suggest that transplant coronary artery disease has a dual etiology based on the dichotomous pattern of atherosclerosis seen by intravascular ultrasound.

Lack of ventricular remodeling in non-Q-wave myocardial infarction.

We prospectively examined 45 patients with serial echocardiography to measure left ventricular end-diastolic volume index within 1 week and at 6 weeks after infarction. Left ventricular volume increased in patients with Q-wave infarction but not in those with non-Q or in control patients without recent infarction. Peak creatine phosphokinase levels were greater in Q-wave infarction compared with those in non-Q-wave infarction. There was a strong correlation between the change in the left ventricular end-diastolic index and the peak creatine phosphokinase level. After correcting for infarct size, there was still a difference between the two groups. Our data indicate that ventricular remodeling does not occur in non-Q-wave as opposed to Q-wave infarcts, and this may be related both to the limited amount of myocardial necrosis and to the nontransmural extent of the necrosis.

Fetal fibronectin in vaginal specimens predicts preterm delivery and very-low-birth-weight infants.

OBJECTIVE: The purpose of this study was to evaluate the association of vaginal fetal fibronectin expression to risk of preterm delivery and delivery of very-low-birth-weight infants. STUDY DESIGN: Vaginal secretions were obtained from women between 22 and 35 weeks' pregnant with minimal cervical dilation (< or = 2 cm) and threatened preterm delivery. The secretions were analyzed for the presence of fetal fibronectin. Other clinical information including cervical dimensions, uterine activity, serum C-reactive protein concentration, vaginal pH, evidence of vaginal or systemic infection, and vaginal bleeding were also obtained. RESULTS: Of the 112 patients recruited, 40 (35.7%) were delivered prematurely (<37 weeks). For prediction of preterm delivery, the fetal fibronectin test result had a sensitivity, specificity, and positive and negative predictive values of 67.5, 90.3, 79.4, and 83.3%, respectively (odds ratio 19.3, p < 0.0001). Women with a positive fetal fibronectin test had a nearly 13-fold increased probability of being delivered of an infant weighing <1500 gm than did women with a negative fetal fibronectin test (32.4% vs 2.5%, p<0.0001). Categoric analysis and multiple logistic regression demonstrated that fetal fibronectin was an independent risk factor for prediction of preterm delivery and birth weight <1500 gm. CONCLUSION: Vaginal fetal fibronectin expression is an independent risk factor for preterm delivery and birth of very-low-birth-weight infants in symptomatic women with intact amniotic membranes and minimal cervical dilatation.
