AimsHypertensive disorders of pregnancy (HDP) predict future cardiovascular events. We aim to investigate relations between HDP history and subsequent hypertension (HTN), myocardial structure and function, and late gadolinium enhancement (LGE) scar.Methods and resultsWe evaluated a prospective cohort of women with suspected ischaemia with no obstructive coronary artery disease (INOCA) who underwent stress/rest cardiac magnetic resonance imaging (cMRI) with LGE in the Women’s Ischemia Syndrome Evaluation-Coronary Vascular Dysfunction study. Self-reported history of pregnancy and HDP (gestational HTN, pre-eclampsia, toxaemia and eclampsia) were collected at enrollment. In our cohort of 346, 20% of women report a history of HDP. HDP history was associated with 3.2-fold increased odds of HTN. Women with a history of both HDP and HTN had higher cMRI measured left ventricular (LV) mass compared with women with HDP only (99.4±2.6 g vs 87.7±3.2 g, p=0.02). While we found a similar frequency of LGE scar, we observed a trend towards increased LGE scar size (5.1±3.4 g vs 8.0±3.4 g, p=0.09) among the women with HDP history compared to women without.ConclusionIn a high-risk cohort of women with suspected INOCA, 20% had a history of HDP. Women with HDP history were more likely to develop HTN. Our study demonstrates higher LV mass in women with HDP and concomitant HTN. Although the presence of LGE scar was not different in women with and without HDP history, we observed a trend towards larger scar size in women with HDP. Future studies are needed to better assess the relationship of HDP and cardiac morphology and LGE scarring in a larger cohort of women.

Abstract Introduction A history of hypertensive disorders of pregnancy (HDP) has the unique potential to identify women at higher risk of future maternal cardiovascular disease (CVD), for whom targeted risk-reduction interventions may be particularly helpful. Purpose The aim of the study was to assess the factors and biomarkers of cardiometabolic risk in women with a history of hypertensive disorders of pregnancy. Methods Cross-sectional study of risk factors and biomarkers of cardiometabolic risk among young women with a history of HDP in comparison with normotensive patients during pregnancy. 117 women were studied: gr. 1 – 33 with a history of HDP, 40 [40–43] years; gr. 2 – 44 without a history of HDP, 39 [32–43] years. The control group consisted of 40 patients, 25 [23–28] years. The time interval after delivery was on average 5 to 19 years. We measured serum glucose, insulin, HOMA-IR, lipids, leptin, adiponectin. Left ventricular mass index (LVMI) was estimated by TTE. Data are presented as M±SD and Me (Q25–Q75). Results Women with HDP more often had hypertension (n=27; 82%), obesity (n=20; 39%) and smoking (n=9; 27%), p1–2,3 <0.05. A higher plasma levels of glucose mmol/L (5.5±0.7 vs 5.2±0.6 and 5.1±0.5), leptin ng/ml (42 [30–50] vs 24 [13–32] and 19 [10–29]) and lower plasma levels of adiponectin were observed in gr.1 vs gr. 2 and controls. Mean value of LVMI (g/m2) was statistically higher in women with HDP vs. without HDP and controls (119.9±23.7 vs 85.9±15.2 and 77.6±11.3), p1–2,3 <0.05. Conclusion It is shown that in women with a history of HDP subsequent changes in carbohydrate and lipid metabolism in combination with arterial hypertension and abdominal obesity, which constitute a cluster of the metabolic syndrome, are revealed after careful examination. These changes are also accompanied by insulin resistance, hyperinsulinemia, adipokine imbalance and more pronounced target organ damage.

In 17 patients with end-stage renal disease, we evaluated the effects of treatment with CAPD on L V anatomy and function by M -mode echocardiography. All patients had a history of hypertension and had echocardiographic evidence of increased LV mass related to both concentric and eccentric hypertrophy. On CAPD, blood pressure returned to normal in a consistent manner. L V mass decreased in most (14/17) patients as a result of a decrease in both L V wall thickness and LV dimension. Initially four of the 17 patients had diminished LV function. On CAPD, LV function improved in three of these four and no patient showed deterioration. These results indicate that CAPD improves L V hypertrophy and L V function by normalizing both pressure and volume overload.

Abstract Background We aimed to identify sex differences in the network properties and to recognize the geometric alteration effects of long-term swim training in a rat model of exercise-induced left ventricular (LV) hypertrophy. Methods Thirty-eight Wistar rats were divided into four groups: male sedentary, female sedentary, male exercised and female exercised. After training sessions, LV morphology and function were checked by echocardiography. The geometry of the left coronary artery system was analysed on pressure-perfused, microsurgically prepared resistance artery networks using in situ video microscopy. All segments over > 80 μm in diameter were studied using divided 50-μm-long cylindrical ring units of the networks. Oxidative-nitrative (O-N) stress markers, adenosine A2A and estrogen receptor (ER) were investigated by immunohistochemistry. Results The LV mass index, ejection fraction and fractional shortening significantly increased in exercised animals. We found substantial sex differences in the coronary network in the control groups and in the swim-trained animals. Ring frequency spectra were significantly different between male and female animals in both the sedentary and trained groups. The thickness of the wall was higher in males as a result of training. There were elevations in the populations of 200- and 400-μm vessel units in males; the thinner ones developed farther and the thicker ones closer to the orifice. In females, a new population of 200- to 250-μm vessels appeared unusually close to the orifice. Conclusions Physical activity and LV hypertrophy were accompanied by a remodelling of coronary resistance artery network geometry that was different in both sexes.

Myxomas arising from the left ventricle (LV) are extremely rare and can be easily mistaken for a thrombus. We report a case of a 35-year-old man who presented with an acute cerebrovascular accident, having had a prior history of an anterior wall myocardial infarction 2 years back with an echocardiographic evaluation showing mild LV systolic dysfunction. His present prothrombotic workup revealed hyperhomocystinaemia and elevated levels of factor VIII. Present echocardiography revealed a mass arising from a scarred LV wall. Considering the possibility of a thrombus, he was initially started on parenteral anticoagulation. Unfortunately, consequent echocardiogram evaluation showed no reduction in size of the LV mass hence surgical removal was done. Histopathological evaluation unveiled the mass to be a myxoma.

Background: Cardiovascular functions and hemodynamics dramatically change during pregnancy such as cardiac output, expanded blood volume, reduced systematic vascular resistance, and heart chamber enlargement. Hypertensive disorders of pregnancy (HDP) may affect the cardiac load during pregnancy; however, the data about plasma concentration of cardiac troponin in pregnant women with HDP is very limited. Methods: We prospectively collected data of 751 pregnant women between 2012 and 2013 in Japanese general hospital. We analyzed laboratory data and echocardiographic findings after delivery. The elevated cTnI was defined as >0.015 ng/mL because the normal population have serum cTnI of less than 0.015 ng/mL in this assay. Results: The HDP were observed in 32 patients; the elevated cTnI was observed 40 patients. The age of patients with HDP (33.7 ±4.3 years) was not different from that of those without HDP (33.3 ± 5.0 years). The brain natriuretic peptides levels were not different between those with and without HDP. The proportion of elevated cTnI was higher in those with HDP (21.8%) than those without (3.6%, P<0.0001). After adjusting for confounders, the risk of elevated cTnI in those with HDP relative to those without HDP remained significant (odds ratio 4.52, 95% confidence interval 1.45-14.5). There were no women with reduced left ventricular ejection fraction. Conclusions: HDP was associated with elevated cTni, suggesting myocardial microinjury might occur more frequently in those with HDP.

ObjectivesCompare the predictive performance of Framingham Risk Score (FRS), Pooled Cohort Equations (PCEs) and Systematic COronary Risk Evaluation (SCORE) model between women with and without a history of hypertensive disorders of pregnancy (hHDP) and determine the effects of recalibration and refitting on predictive performance.MethodsWe included 29 751 women, 6302 with hHDP and 17 369 without. We assessed whether models accurately predicted observed 10-year cardiovascular disease (CVD) risk (calibration) and whether they accurately distinguished between women developing CVD during follow-up and not (discrimination), separately for women with and without hHDP. We also recalibrated (updating intercept and slope) and refitted (recalculating coefficients) the models.ResultsOriginal FRS and PCEs overpredicted 10-year CVD risks, with expected:observed (E:O) ratios ranging from 1.51 (for FRS in women with hHDP) to 2.29 (for PCEs in women without hHDP), while E:O ratios were close to 1 for SCORE. Overprediction attenuated slightly after recalibration for FRS and PCEs in both hHDP groups. Discrimination was reasonable for all models, with C-statistics ranging from 0.70-0.81 (women with hHDP) and 0.72–0.74 (women without hHDP). C-statistics improved slightly after refitting 0.71–0.83 (with hHDP) and 0.73–0.80 (without hHDP). The E:O ratio of the original PCE model was statistically significantly better in women with hHDP compared with women without hHDP.ConclusionsSCORE performed best in terms of both calibration and discrimination, while FRS and PCEs overpredicted risk in women with and without hHDP, but improved after recalibrating and refitting the models. No separate model for women with hHDP seems necessary, despite their higher baseline risk.
