Influence of diabetes mellitus on the invasive assessment of myocardial ischemia in patients with coronary artery disease.
Current guidelines recommend physiological evaluation of borderline coronary artery stenoses using hyperemic (fractional flow reserve [FFR]) and nonhyperemic (instantaneous wave‑free ratio [iFR] and resting full‑cycle ratio [RFR]) methods. However, comorbidities, such as diabetes mellitus (DM), may influence the results of the assessment. ⋯ The rate of FFR and iFR/FFR discordance was similar regardless of the diabetes status, and insulin‑treated DM was associated with an increased risk of negative FFR and positive iFR/RFR discordance.

D-dimer in diagnosis and prevention of venous thrombosis: recent advances and their practical implications.
D‑Dimers derive from degradation of cross‑linked fibrin by plasmin, and thus their level is a marker of coagulation and fibrinolytic system activation. Guidelines recommend that D‑dimers are determined if the pretest probability (PTP) is low or intermediate, to exclude venous thromboembolism (VTE), either deep vein thrombosis or pulmonary embolism, and to avoid imaging tests. If the PTP is high or D‑dimer level is above the suggested thresholds, imaging is recommended. ⋯ As a result, there have been several proposals to improve the diagnostic accuracy of D‑dimer levels by adjusting the cutoffs according to patient characteristics, such as age, PTP, pregnancy, renal function, or cancer. D‑Dimer levels can also predict clinical severity of COVID‑19, and escalated anticoagulation based on D‑dimer levels can be associated with a lower risk of mortality in patients with severe COVID‑19. Finally, D‑dimer levels have been incorporated in prediction models for recurrent VTE to help identify patients who may benefit from prolonged anticoagulation.

Randomized Controlled Trial
Long-Term Blood Pressure Control After Hypertensive Pregnancy Following Physician-Optimized Self-Management: The POP-HT Randomized Clinical Trial.
Pregnancy hypertension results in adverse cardiac remodeling and higher incidence of hypertension and cardiovascular diseases in later life. ⋯ In this single-center trial, self-monitoring and physician-guided titration of antihypertensive medications was associated with lower blood pressure during the first 9 months postpartum than usual postnatal outpatient care in the UK.
