ReviewDevelopments and Controversies in Invasive Diagnosis of Coronary Microvascular Dysfunction in Angina With Nonobstructive Coronary Arteries.
Approximately half of all coronary angiograms performed for angina do not show obstructive coronary artery disease, and many of these patients have coronary microvascular dysfunction (CMD). Invasive testing for CMD has increased with the advent and wider availability of thermodilution systems. We review CMD pathophysiology and invasive diagnostic testing using the Doppler and thermodilution systems. We report the results of a PubMed search of invasive microvascular testing and discuss limitations of current diagnostic algorithms in the diagnosis of CMD, including controversies regarding the optimal cutoff value for abnormal coronary flow reserve, use of microvascular resistance indices, and options for increasing sensitivity of testing.

Association Between Cognitive Function and Risk of Chronic Kidney Disease: A Longitudinal Cohort and Mendelian Randomization Study.
To investigate the causal dose-response association between cognitive function and the risk of chronic kidney disease (CKD) by a longitudinal cohort and mendelian randomization study. ⋯ A better cognitive function is causally associated with a lower risk of CKD in participants without prior dementia.

Effects of Colchicine on Major Adverse Limb and Cardiovascular Events in Patients With Peripheral Artery Disease.
To assess the effects of colchicine, which has been shown to reduce the risks of coronary artery disease but scarcely studied in peripheral artery disease (PAD), on major adverse limb events (MALE) in patients with PAD. ⋯ In patients diagnosed with PAD, the use of colchicine is associated with lower risks of MALE and cardiovascular death. Anti-inflammatory therapy with colchicine may provide benefits in vascular beds beyond the coronary arteries.
