Article Synopsis
  • Women with a history of hypertensive disorders during pregnancy face a significantly higher risk of major adverse cardiovascular events after undergoing coronary artery stenting compared to those without such a history.
  • In a study involving over 8,000 women, 13.4% reported hypertensive disorders, and after a median follow-up of 5 years, a notable percentage experienced severe cardiovascular outcomes.
  • The increased hazard rate for these women became evident after 4-8 years following the procedure, particularly impacting those with gestational hypertension.

Background: Women with a history of adverse pregnancy outcomes have a higher risk of coronary heart disease. Emerging evidence suggests that women with a history of preeclampsia have a different pattern of overall coronary atherosclerosis and that they at the time of myocardial infarction (MI) more frequently present with ST-segment elevation MI (STEMI) compared to women with no such history.

Objectives: The purpose of this study was to determine whether among women with MI, those with a history of adverse pregnancy outcomes are more likely to present with STEMI or other clinical characteristics indicating a more severe myocardial injury.

Background: The extent to which a history of hypertensive disorders of pregnancy is associated with incident cardiovascular disease also among women with diabetes is unknown.

Methods: In this nationwide register-based cohort study, parous women aged 18 to 69 years with a first delivery in the Swedish Medical Birth Register, regardless of diabetic status at that time, and a subsequent clinical visit in the Swedish National Diabetes Register were included. Time to first cardiovascular disease event (myocardial infarction, stroke, or heart failure) before age 70 years by hypertensive disorders of pregnancy history was separately analyzed by diabetes type using Cox regression models that included conventional risk factors.

Background: Whereas outdoor temperature is linked to both mortality and hydration status, the hormone vasopressin, measured through the surrogate copeptin, is a marker of cardiometabolic risk and hydration. We recently showed that copeptin has a seasonal pattern with higher plasma concentration in winter. Here, we aimed to investigate the association between outdoor temperature and copeptin.

Background: Women are at a greater risk of a major adverse cardiovascular event (MACE) after percutaneous coronary intervention than men. A history of preterm delivery is a female-specific risk factor for coronary artery disease, but its relevance in the treatment of coronary artery disease is unknown.

Objectives: The purpose of this study was to analyze the association between a history of preterm delivery and MACE after the first coronary artery stenting.

Background A history of preeclampsia is associated with increased risk of coronary artery disease and experimental evidence suggests that a history of preeclampsia also increases the risk of restenosis. However, the extent to which a history of preeclampsia is associated with risk of restenosis after percutaneous coronary intervention in women is unknown. Methods and Results We included 6065 parous women aged ≤65 years with first percutaneous coronary intervention on 9452 segments 2006 to 2017, linking nationwide data on percutaneous coronary intervention and delivery history in Sweden.

Objectives: Studies suggest preeclampsia as a risk factor for long term cardiovascular diseases (CVD), while evidence is limited regarding the risk of high blood pressures (BP) in early pregnancy.

Study Design: A register-based follow-up of 2434 mothers in the Helsingborg Birth Cohort. Associations of high BP in early pregnancy (>95th percentile systolic [SBP], diastolic [BDP], or mean arterial BP [MAP]) during the first antenatal visit and/or preeclampsia with an incident CVD event (ischemic heart disease or stroke) were assessed.

Aims: Heart failure (HF) is a common disease with increasing prevalence and poor prognosis. The vasopressin (VP) marker copeptin predicts development of diabetes mellitus, diabetic heart disease, coronary artery disease, and premature mortality. Copeptin is elevated in HF patients and predicts a worse outcome.

We aimed to determine the relationship between handgrip strength, smoking, and alcohol consumption in young men and fracture risk at middle age. Thus, we carried out a cohort study including young men undergoing conscription examination in Sweden from September 1969 to May 1970 at a typical age of 18 years. Data on muscle strength, height, weight, and lifestyle factors were linked to the National Patient Register 1987-2010.

Aim: To evaluate whether history of pregnancy complications [pre-eclampsia, gestational hypertension, preterm delivery, or small for gestational age (SGA)] improves risk prediction for cardiovascular disease (CVD).

Methods And Results: This population-based, prospective cohort study linked data from the HUNT Study, Medical Birth Registry of Norway, validated hospital records, and Norwegian Cause of Death Registry. Using an established CVD risk prediction model (NORRISK 2), we predicted 10-year risk of CVD (non-fatal myocardial infarction, fatal coronary heart disease, and non-fatal or fatal stroke) based on established risk factors (age, systolic blood pressure, total and HDL-cholesterol, smoking, anti-hypertensives, and family history of myocardial infarction).

Background: Women with a history of hypertensive disorders of pregnancy (HDP) are at increased risk of hypertension, cardiovascular disease, and type 2 diabetes. Offspring from pregnancies complicated by HDP also have worse cardiometabolic status in childhood and young adulthood, but the offspring risk of clinical hypertension in adulthood is largely unknown.

Methods: We studied 13,893 first-born adult offspring (49.

Background: Ischemic heart disease and stroke are two severe types of cardiovascular disease (CVD), a major contributor to the global burden of disease. The preventive framework currently includes promotion of both adequate cardiorespiratory and muscular fitness. Although muscle fitness is established as an indicator of health, it is currently unknown whether muscle strength is associated with later CVD independently of cardiorespiratory fitness.
