Objective: Sex-specific low flow was recently defined as stroke volume index (SVi) ≤40 ml/m² in men and ≤32 ml/m² in women. We tested the prognostic association of these cut-offs in patients with aortic stenosis (AS) with concordantly and discordantly graded AS (CGASEL and DGASEL) based on pressure recovery adjusted aortic valve area (energy loss, EL).

Methods: Data from 1351 patients with asymptomatic AS, peak jet velocity <4m/s and preserved left ventricular ejection fraction enrolled in the Simvastatin and Ezetimibe in AS study was used.

Article Synopsis
  • Rheumatoid arthritis (RA) is more common in women and linked to cardiovascular issues like hypertension and arterial stiffness; researchers studied changes in arterial stiffness in RA patients on DMARD therapy.
  • In a study of 77 RA patients, while disease activity (DAS28) improved over 22 months, arterial stiffness (measured by increasing pulse wave velocity) worsened, especially in those with higher baseline blood pressure, diabetes, and body mass index.
  • The findings suggest that managing cardiovascular risk factors is crucial for RA patients, as improvement in disease activity does not necessarily prevent increased arterial stiffness.

Background: Progressive arterial stiffening may increase the risk of recurrent cardiovascular events in ischemic stroke survivors. Information about factors associated with progressive arterial stiffening during the follow-up of young patients with ischemic stroke is lacking.

Methods: Arterial stiffness by carotid-femoral pulse wave velocity (cf-PWV) and ambulatory 24-hour blood pressure (24hBP) were assessed in 81 women and 190 men ≤60 years of age included in the Norwegian Stroke in the Young (NOR-SYS) study 3 months and 5.

Article Synopsis
  • The study examined the global myocardial work index (GWI), a new measure of heart function, in relation to sex and body mass index (BMI) among 467 individuals without known heart disease.
  • Women had higher BMI, aortic augmentation pressure, left ventricular global longitudinal strain (GLS), and GWI compared to men, with these differences being statistically significant.
  • The higher GWI in women was linked to increased left ventricular workload due to higher aortic augmentation pressure, which explained the sex difference but became non-significant when accounting for other hemodynamic factors.

  • Obesity is linked to increased arterial stiffness, but sex differences in this association have not been thoroughly investigated.
  • A study examined the arterial stiffness of 323 women and 225 men with overweight and obesity, finding that women had higher augmentation pressure (AP) and augmentation index (AIx), while men had higher carotid-femoral pulse wave velocity (cf-PWV).
  • Both age and 24-hour systolic blood pressure were significant factors affecting arterial stiffness in all subjects, while body fat measures like BMI had minimal influence.

Article Synopsis
  • Hypertension is a significant cardiovascular risk factor for patients with ankylosing spondylitis (AS), but its connection to cardiovascular organ damage is not well understood.* ! -
  • In a study of 126 AS patients, 34% had hypertension, which was linked to a high prevalence of cardiovascular organ damage (84%) compared to those without hypertension (29%) and healthy controls (30%).* ! -
  • The findings highlight that managing hypertension is crucial for minimizing cardiovascular organ damage in AS patients, as it substantially increases their risk.* !

Article Synopsis
  • The study aimed to investigate whether patients with asymptomatic aortic stenosis (AS) showing discordant grading after adjusting for pressure recovery have a higher cardiovascular risk.
  • Data from 1,353 patients enrolled in a specific study revealed that 14.5% had discordantly graded aortic stenosis (DGAS), which was linked to older age, female gender, and other risk factors.
  • Cox regression analysis demonstrated that DGAS significantly increased the risk of heart failure hospitalization, cardiovascular death, and all-cause mortality, independent of other factors.

Article Synopsis
  • - The study analyzed the connection between inflammation markers and blood pressure (BP) in midlife participants (3280 individuals) over 6 years, focusing on sex differences in these associations.
  • - Results showed that women exhibited lower average BP than men and that higher levels of inflammatory markers like hs-CRP were linked to increased BP specifically in women, not men.
  • - The findings indicate that inflammation and its impact on BP and hypertension differ between sexes, underscoring the importance of considering sex-specific factors in cardiovascular health research.

Psoriasis is an immune mediated disorder associated with T cell activation and cardiovascular disease (CVD). We explored the association of inflammation with left ventricular (LV) remodelling in psoriasis patients receiving treatment with the tumour necrosis factor-α (TNF-α) blocker infliximab. Psoriasis patients ( = 47, age 47 ± 14 years, 66% men) and 99 control subjects without psoriasis (age 47 ± 11 years, 72% men) were examined by echocardiography in a cross-sectional study.

Objective: We compared persistent cardiac organ damage in patients treated surgically or medically for primary aldosteronism.

Methods: Eighty-four patients (age 57 ± 11 years, 27% women) with primary aldosteronism underwent echocardiography at time of diagnosis and after one year of treatment (49% adrenalectomy, 51% medical treatment). Persistent cardiac organ damage was defined as presence of left ventricle (LV) hypertrophy, low LV midwall shortening, global longitudinal strain and/or enlarged left atrium both at baseline and at follow-up.

Article Synopsis
  • Researchers investigated how low myocardial energetic efficiency (MEEi) could predict mortality in asymptomatic aortic stenosis (AS) patients without diabetes or known cardiovascular disease.
  • Data from 1,703 AS patients were analyzed over 4.3 years, revealing that an MEEi value below 0.34 mL/s per gram correlated with a higher risk of cardiovascular and all-cause mortality.
  • The study concluded that low MEEi reflects increased cardiometabolic risk and reduced left ventricular function, independently predicting worse outcomes in this patient group.

We explored the association between subclinical cardiac organ damage (OD) with comorbidities and psoriasis severity in 53 psoriasis patients on infliximab treatment (age 47 ± 15 years, 30% women) and 99 controls without psoriasis (age 47 ± 11 years, 28% women). Cardiac OD was assessed by echocardiography as the presence of increased left ventricular (LV) relative wall thickness (RWT), LV hypertrophy or dilated left atrium. Psoriasis severity was graded using the psoriasis area and severity index (PASI).

Lower myocardial mechanic-energetic efficiency (MEEi), expressed as stroke volume/heart rate ratio (SV/HR) in mL/s/g of the left ventricular (LV) mass, is associated with the incidence of heart failure in subjects with cardiometabolic disorders. We explored the association of MEEi with LV systolic circumferential and longitudinal myocardial function in 480 subjects with increased body mass index (BMI) without known cardiovascular disease (mean age 47 ± 9 years, 61% women, 63% obese, 74% with hypertension) participating in the fat-associated cardiovascular dysfunction (FATCOR) study. Insulin resistance was assessed by the homeostasis model assessment insulin-resistance index (HOMA-IR).

Pulmonary embolism (PE) is associated with serious morbidity and mortality. In this case report, we describe a hemodynamically stable patient with submassive PE and a large thrombus in the inferior vena cava (IVC) protruding into the right atrium (RA), complicated by severe respiratory failure, elevated troponin T (TnT), and right ventricular (RV) dysfunction. The patient was stratified as intermediate-high risk of early death.
