Guideline-driven management of hypertension: an evidence-based update.
This paper is an evidence-based update to the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline. The authors conducted a literature review of relevant observational studies, randomized clinical trials, and meta-analyses published between January 2018 and March 2021. Topics included blood pressure (BP) measurement, patient evaluation, patient evaluation for secondary hypertension, cardiovascular disease risk assessment and BP threshold for drug therapy, lifestyle and pharmacological management, treatment target BP goal, management of hypertension in older adults, diabetes, chronic kidney disease, resistant hypertension, and optimization of care using patient, provider, and health system approaches.

Association of blood pressure variability and diuretics with cardiovascular events in patients with chronic kidney disease stages 1-5.
This study looked at whether blood pressure variability (BPV) is associated with cardiovascular outcomes and end-stage kidney disease (ESKD) in patients with chronic kidney disease. The authors studied US veterans with nondialysis chronic kidney disease stages 1-5 and hypertension on nondiuretic antihypertensive monotherapy. This case-control study compared veterans on only one antihypertensive prescription with those who were prescribed a second antihypertensive prescription. Each group had 31,394 participants. BPV was associated with composite cardiovascular events. It was associated with cardiovascular events and death but not ESKD in patients with chronic kidney disease.

Effect of concomitant deep venous reflux on truncal endovenous ablation outcomes in the Vascular Quality Initiative.
This study looked at outcomes for patients with varicose veins (C2 disease) undergoing truncal endovenous ablation with and without deep venous reflux. Data from the Vascular Quality Initiative was analyzed from 2015 to 2019. A total of 4881 patients were included, with 46.2% having combined deep and superficial reflux. Follow-up around a year later (median 336.5 days) was conducted after. Patients with deep reflux were less likely to be female, more likely to be Caucasian, and had no difference in BMI. Additionally, there were no differences in rates of prior varicose vein treatments, number of pregnancies, or history of deep venous thrombosis. However, patients without deep reflux were more likely to use anticoagulants at the time of the procedure. Patients without deep reflux had slightly higher median preprocedural Venous Clinician Severity Score (VCSS) scores as well as postprocedural VCSS scores. Total symptom score was higher for patients without deep reflux before and after the procedure, but there was no change in symptom score after the procedure. Patients with deep reflux had substantially higher rates of complications with a particular increase in proximal thrombus extension.

Outcomes after truncal ablation with or without concomitant phlebectomy for isolated symptomatic varicose veins (C2 disease).
This study looked outcomes of patients with varicose veins (C2 disease) who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry. Data between January 2015 and March 2015 was used to investigate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy. Out of 3375 patients, 40.1% underwent isolated truncal ablation and the rest had the combined procedure of ablation and phlebectomy. Complications were low for both procedures (8.4% and 8.7%). Overall, improvement in symptoms was experienced by 94.4% of patients with more increases in patients undergoing ablation and phlebectomy than ablation alone. Both procedures are recommended by the authors to be covered by insurance.

Risk of kidney failure, death, and cardiovascular events after lower limb complications in patients with CKD.
Investigators sought to determine how interim lower limb complications modify the subsequent risk of progression to kidney failure, all-cause mortality before kidney failure, and cardiovascular events in a cohort of patients with chronic kidney disease (CKD) stages G3 to G5. Patient-level data obtained from several administrative databases from Manitoba, Canada, were analyzed. They found that interim lower limb complications were associated with an increased risk of kidney failure, all-cause mortality before kidney failure, and cardiovascular-related hospitalization. They stated that clinical trials of screening and treatment strategies for patients with CKD at risk for lower limb complications may help determine optimal strategies to manage this risk.

Comparison of unilateral vs bilateral and staged bilateral vs concurrent bilateral truncal endovenous ablation in the Vascular Quality Initiative.
This study compares outcomes in patients who have undergone unilateral vs bilateral venous ablation procedures or between staged and concurrent bilateral procedures. Data from the Vascular Quality Initiative from 2015 to 2019 was used to investigate immediate postoperative as well as long-term clinical and patient-reported outcomes. A total of 5029 patients were included, of whom 75.2% underwent unilateral procedures. Follow-up was conducted with a median of 227 days after. Unilateral patients were less likely to be female and white and had lower BMI compared with patients undergoing bilateral procedures. In addition, unilateral patients had fewer prior varicose vein treatments and had higher Venous Clinical Severity Scores (VCSS). There were no differences in complications in patients undergoing unilateral vs bilateral procedures. Systemic complications were rare in both groups.
