Abstract
RATIONALE & OBJECTIVE It is unknown whether initiating renin-angiotensin system (RAS) inhibitor therapy in patients with advanced chronic kidney disease (CKD) is superior to alternative antihypertensive agents such as calcium channel blockers (CCBs). We compared the risks for kidney replacement therapy (KRT), mortality, and major adverse cardiovascular events (MACE) in patients with advanced CKD in routine nephrology practice who were initiating either RAS inhibitor or CCB therapy. STUDY DESIGN Observational study in the Swedish Renal Registry, 2007 to 2017. SETTINGS & PARTICIPANTS 2,458 new users of RAS inhibitors and 2,345 CCB users with estimated glomerular filtration rates<30mL/min/1.73m2 (CKD G4-G5 without KRT) who were being followed up by a nephrologist. As a positive control cohort, new users of the same drugs with CKD G3 (estimated glomerular filtration rate, 30-60mL/min/1.73m2) were evaluated. EXPOSURES RAS inhibitor versus CCB therapy initiation. OUTCOME Initiation of KRT (maintenance dialysis or transplantation), all-cause mortality, and MACE (composite of cardiovascular death, myocardial infarction, or stroke). ANALYTICAL APPROACH HRs with 95% CIs were estimated using propensity score-weighted Cox proportional hazards regression adjusting for demographic, clinical, and laboratory covariates. RESULTS Median age was 74 years, 38% were women, and median follow-up was 4.1 years. After propensity score weighting, there was significantly lower risk for KRT after new use of RAS inhibitors compared with new use of CCBs (adjusted HR, 0.79 [95% CI, 0.69-0.89]) but similar risks for mortality (adjusted HR, 0.97 [95% CI, 0.88-1.07]) and MACE (adjusted HR, 1.00 [95% CI, 0.88-1.15]). Results were consistent across subgroups and in as-treated analyses. The positive control cohort of patients with CKD G3 showed similar KRT risk reduction (adjusted HR, 0.67 [95% CI, 0.56-0.80]) with RAS inhibitor therapy compared with CCBs. LIMITATIONS Potential confounding by indication. CONCLUSIONS Our findings provide evidence from real-world clinical practice that initiation of RAS inhibitor therapy compared with CCBs may confer kidney benefits among patients with advanced CKD, with similar cardiovascular protection.

Abstract
BACKGROUND The aim of this study is to compare the long-term prognosis of non-ST elevation acute coronary syndrome (NSTE-ACS) patients with 3-vessel disease (3VD) who underwent percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) or medical therapy (MT).Methods and Results:Overall, 3,928 NSTE-ACS patients with 3VD were consecutively enrolled from April 2004 to February 2011 at Fu Wai Hospital. Patients were followed up for a median of 7.5 years, and were divided into PCI, CABG or MT groups according to their treatment. Compared with patients undergoing PCI, CABG patients had lower rates of myocardial infarction (MI), unplanned revascularization, major adverse cardiovascular and cerebrovascular events (MACCE) and a higher rate of stroke (all P<0.05). Compared with MT, PCI and CABG had lower incidences of all adverse outcomes (all P<0.05), except for a similar rate of stroke between PCI and MT. Kaplan-Meier analysis showed similar results. After adjusting for confounders, CABG was independently associated with a lower risk of cardiac death, revascularization and MACCE compared with PCI (all P<0.05). Compared with MT, PCI reduced long-term risk of death, whereas CABG reduced long-term risk of death, revascularization and MACCE events (all P<0.05). CONCLUSIONS In NSTE-ACS patients with 3VD, CABG is independently associated with a lower risk of long-term cardiac death, revascularization and MACCE compared with PCI. Patients who received MT alone had the highest risk of long-term MACCE.

Abstract
INTRODUCTION Albuminuria is an early marker of kidney disease and reduction of albuminuria translates into a decreased occurrence of cardiovascular and renal outcomes. AIMS To evaluate the changes in the prevalence of albuminuria in diabetic hypertensive patients treated with several combinations of renin-angiotensin aldosterone system with calcium channel blockers. METHODS We analysed data from 668 unselected patients from the PAIT survey (mean age 60.4 ± 10.2 years, prevalence of males 38%), with and without albuminuria, maintained for 6 months with the previous treatment with amlodipine-valsartan, amlodipine perindopril, lercanidipine-enalapril, verapamil-trandolapril, nitrendipine-enalapril and felodipine-ramipril Albuminuria was assessed, as urinary albumin-creatinine ratio, using a Multistic-Clinitek device analyzer. Microalbuminuria was defined as a loss of 3.4-33.9 mg albumin/mmol creatinine (30-300 mg/g) and macroalbuminuria as a loss of > 33.9 mg albumin/mmol creatinine (> 300 mg/g). Blood pressure was measured with a validated digital device. RESULTS At baseline, albuminuria was present in 310 subjects (46.4%) (microalbuminuria in 263 (84.8%), macroalbuminuria in 15.2%), and normoalbuminuria in 53.6% 358. After 6 months, the prevalence of subjects with albuminuria was significantly lowered (p < 0.01) by 23.5% (microalbuminuria - 23.9%, p < 0.01 and macroalbuminuria - 21.3%). The prevalence of subjects with microalbuminuria was reduced with all treatments: amlodipine-valsartan - 15.6%, amlodipine-perindopril - 11.8%, lercanidipine-enalapril - 41.3% and verapamil-trandolapril - 19.2%. Data with nitrendipine-enalapril and felodipine-ramipril were not analyzed, due to the low number of patients. The frequency of patients with normoalbuminuria was significantly higher (p < 0.01) with lercanidipine-enalapril compared with any other treatment. Blood pressure was significantly (p < 0.01) reduced, with a similar effect between treatments. CONCLUSIONS The treatments decrease the prevalence of subjects with albuminuria, showing a significant difference among the different drug combinations, favoring the use of new dihydropyridine calcium channel blockers, such as lercanidipine, combined with RAAS inhibitors, to control albuminuria in diabetic hypertensive patients.

Abstract
BACKGROUND Drug-eluting stent-induced vasospastic angina (DES-VSA) has emerged as a novel complication in the modern era of percutaneous coronary intervention (PCI). Although beta blockers (BBs) are generally recommended for coronary heart disease, they may promote incidence of DES-VSA. This study aimed to compare the effects of calcium channel blockers (CCBs) perceived to be protective against DES-VSA and BBs on subsequent coronary events after second-generation drug-eluting stent implantation. METHODS In this multicentre prospective, randomised study, 52 patients with coronary artery disease who underwent PCI for a single-vessel lesion with everolimus-eluting stent placement were randomised into post-stenting BB (N=26) and CCB (N=26) groups and followed for 24 months to detect any major cardiovascular events (MACE). A positive result on acetylcholine provocation testing during diagnostic coronary angiography (CAG) at 9 months was the primary endpoint for equivalence. MACE included all-cause death, non-fatal myocardial infarction, unstable angina, cerebrovascular disease or coronary revascularisation for stable coronary artery disease after index PCI. RESULTS At 9 months, 42 patients (80.8%) underwent diagnostic coronary angiography and acetylcholine provocation testing. Among them, seven patients in each group were diagnosed with definite vasospasm (intention-to-treat analysis 26.9% vs 26.9%, risk difference 0 (-0.241, 0.241)). Meanwhile, the secondary endpoint, 24-month MACE, was higher in the CCB group (19.2%) than in the BB group (3.8%) (p=0.01). In detail, coronary revascularisation for stable coronary artery disease was the predominant endpoint that contributed to the greater proportion of MACE in the CCB group (CCB (19.2%) vs BB (3.8%), p=0.03). CONCLUSIONS The incidence of acetylcholine-induced coronary artery spasms did not differ between patients receiving BBs or CCBs at 9 months after PCI. However, a higher incidence of 2-year MACE was observed in the CCB group, suggesting the importance of BB administration. TRIAL REGISTRATION NUMBER This study was registered at the Japanese University Hospital Medical Information Network (UMIN) Clinical Trial Registry (The Prospective Randomized Trial for Optimizing Medical Therapy After Stenting: Calcium-Beta Trial; UMIN000008321, https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000009536).

Özdemir, HI, van Dijk, CHB, Özdemir, AB, van Straten, BHM, Haanschoten, M, Soliman-Hamad, MA
Journal of cardiac surgery. 2019;(12):1505-1510
Abstract
BACKGROUND AND AIM OF THE STUDY In vitro studies have shown a reduction in radial artery spasm with the use of calcium antagonists. The purpose of this study was to evaluate the efficacy of topical treatment of the radial artery conduit using either verapamil or nicardipine before the anastomoses. METHODS This prospective randomized study included 131 patients, who underwent coronary artery bypass grafting surgery with the use of the radial artery as a conduit. In 65 patients, the harvested radial artery was topically treated with verapamil and in 66 patients with nicardipine. After harvesting the radial artery, the direct flow through the conduit was measured in vitro before 5-minute incubation in nicardipine or verapamil and measured again after incubation. The flow before and after incubation was compared. Postincubation flow was also compared in the two groups. After performing the anastomosis, the flow through the radial artery was measured in vivo. RESULTS The mean flow after NaCl incubation was 19.93 ± 12.66 mL/min and after incubation in the Ca+ channel blocker 47.16 ± 14.58 mL/min (P < .001). No significant difference in postincubation free flow was found between verapamil (46.29 ± 15.43 mL/min) and nicardipine (48.01 ± 13.77 mL/min; P = .503). CONCLUSION Topical treatment with Ca+ channel blockers reduces radial artery spasm and significantly increases the free flow through the radial artery conduit. Nicardipine is a safe and effective alternative of verapamil in preventing spasm of radial artery conduit.

[Effect of magnesium sulphate and milrinone on cerebral vasospasm after aneurysmal subarachnoid hemorrhage: a randomized study].
Soliman, R, Zohry, G
Brazilian journal of anesthesiology (Elsevier). 2019;(1):64-71
Abstract
BACKGROUND Aneurysmal subarachnoid hemorrhage is an important cause of premature death and disability worldwide. Magnesium sulphate is shown to have a neuroprotective effect and it reverses cerebral vasospasm. Milrinone is also used in the treatment of cerebral vasospasm. The aim of the present study was to compare the effect of prophylactic magnesium sulphate and milrinone on the incidence of cerebral vasospasm after subarachnoid hemorrhage. METHODS The study included 90 patients with aneurysmal subarachnoid hemorrhage classified randomly (by simple randomization) into two groups: magnesium sulphate was given as an infusion of 500 mg.day−1 without loading dose for 21 days. Group B: milrinone was given as an infusion of 0.5 μg.kg−1.min−1 without loading dose for 21 days. The cerebral vasospasm was diagnosed by mean cerebral blood flow velocity in the involved cerebral artery (mean flow velocity ≥ 120 cm.s−1), neurological deterioration by Glasgow coma scale, or angiography (the decrease in diameter of the involved cerebral artery >25%). RESULTS The mean cerebral blood flow velocity decreased significantly in the magnesium group compared to milrinone group through Day 7, Day 14 and Day 21 (p < 0.001). The incidence of cerebral vasospasm decreased significantly with magnesium compared to milrinone (p = 0.007). The Glasgow coma scale significantly improved in the magnesium group compared to milrinone group through Day 7, Day 14 and Day 21 (p = 0.036, p = 0.012, p = 0.016, respectively). The incidence of hypotension was higher with milrinone than magnesium (p = 0.012). CONCLUSIONS The incidence of cerebral vasospasm after aneurysmal subarachnoid hemorrhage was significantly lower and Glasgow coma scale significantly better with magnesium when compared to milrinone. Milrinone was associated with a higher incidence of hypotension and requirement for dopamine and norepinephrine when compared to magnesium.

Comparison of amlodipine versus other calcium channel blockers on blood pressure variability in hypertensive patients in China: a retrospective propensity score-matched analysis.
Zhang, L, Yang, J, Li, L, Liu, D, Xie, X, Dong, P, Lin, Y
Journal of comparative effectiveness research. 2018;(7):651-660
Abstract
AIM: Reducing the fluctuation of blood pressure has recently been recognized as a potential target for improving management of hypertension to prevent cardiovascular events, particularly for strokes. Some randomized controlled trials demonstrated that amlodipine can effectively reduce blood pressure as a well-established, long-acting calcium channel blocker (CCB). However, few data are available for amlodipine on blood pressure variability (BPV) in China in a real-world setting. This study aimed to assess the effect of amlodipine versus other CCB antihypertensive agents on BPV. MATERIALS & METHODS A retrospective propensity score-matched analysis was conducted, which retrieved the encounter data from 5582 hypertensive inpatients (with a median age of 69, female percentage of 48%, diastolic blood pressure ≥40 and <150 mmHg; systolic blood pressure (SBP) ≥70 mmHg and <260 mmHg), who had taken at least one antihypertensive agent and completed at least three SBP measurements during the visit. International Classification of Diseases was used to identify the hypertensive patients. BPV was calculated with standard deviation (SD) and coefficient of variation (CV) of SBP during a single inpatient visit. The Propensity Score Matching was used to balance the cohort of patients prescribed amlodipine or other CCBs. A series of appropriate statistical tests were applied to the propensity score-matched samples to examine the different effects on BPV. Additionally, the hypertensive patients with comorbidity such as coronary artery disease, diabetes mellitus, myocardial infarction, heart failure and chronic kidney disease were analyzed. RESULTS For the hypertensive patients (n = 1756, for each cohort), patients prescribed amlodipine showed lower BPV than patients prescribed other CCBs (12.90 vs 13.76 mmHg, p < 0.05 [SD] and 9.47 vs 10.06, p < 0.05 [CV]). For the hypertensive patients with comorbidity (n = 1080, for each cohort), patients prescribed amlodipine had lower BPV than patients prescribed other CCBs as well (13.24 vs 14.23 mmHg, p < 0.05 [SD] and 9.66 vs 10.28, p < 0.05 [CV]). CONCLUSION amlodipine was associated with lower BPV than other CCBs for both hypertensive patients and hypertensive patients with comorbidity.

Fujiwara, T, Yano, Y, Hoshide, S, Kanegae, H, Hashimoto, J, Kario, K
American journal of hypertension. 2018;(9):995-1001
Abstract
BACKGROUND We aimed to assess the association of changes in brachial or central nocturnal systolic blood pressure (SBP) with change in urine albumin-creatinine ratio (UACR) by a valsartan/amlodipine combination (80/5 mg) therapy in hypertensive patients. METHODS Twenty-three patients (age range, 47-78 years; mean, 68.0 years; 35% men, 65% with chronic kidney disease) with clinic brachial BP ≥140/90 mm Hg were treated with valsartan/amlodipine combination therapy for 16 weeks. At baseline and 16 weeks later, we measured brachial and central nocturnal SBP using an oscillometric Mobil-O-Graph device and UACR by spot urine in 23 patients. RESULTS The changes in brachial nocturnal SBP (r = 0.445, P = 0.033) and those in central nocturnal SBP (r = 0.616, P = 0.002) were significantly associated with change in UACR by intervention. In multivariable-adjusted multiple regression analyses including changes in both brachial and central nocturnal SBP jointly, only central nocturnal SBP change retained a statistically significant association with change in UACR (β = 0.919, P = 0.020). CONCLUSIONS Lowering central nocturnal SBP by a valsartan/amlodipine combination therapy was associated with reduction of UACR, independently of brachial nocturnal SBP reduction. Central nocturnal SBP may be a therapeutic target to protect the kidney. A larger scale interventional study will be needed to confirm the kidney protection conferred by lowering central nocturnal SBP. CLINICAL TRIALS REGISTRATION Trial Number UMIN000013519.

Burns : journal of the International Society for Burn Injuries. 2018;(6):1482-1488
Abstract
BACKGROUND Keloids and hypertrophic scars are due to overgrowth of dermal collagen following trauma to the skin that usually cause major physical, psychological and cosmetic problems. METHODS In this randomized controlled trial, with a paired design, 50 patients with 2 or more keloids were included. In the control group (50 lesions), intralesional triamcinolone acetonide (40mg/mL) was injected at three-week intervals for a total of 18weeks. In the other group (50 lesions), lesions were treated by verapamil (2.5mg/mL) with the same therapeutic sessions. Scar evaluation at each stage and at the end of 3months follow up was done by serial photographic records as well as by Vancouver Scar Scale (VSS). RESULTS Mean zero VSS scores were achieved with only triamcinolone in respect of scar height (week 15th) and pliability (week 15th). No therapeutic event (parameter=0) or significant improvement was seen in verapamil group. CONCLUSION Our results did not support verapamil's capability in treatment of keloid nor hypertrophic scars.
