Fulltext Beneficial effects of ACE inhibitors in severe mitral stenosis

Sebastian VJ, Bhattacharya S, Ray S, Jaafar SM

Med J Malaysia, 1989 Dec;44(4):291-5.
PMID: 2562442

There are several reports of beneficial effects of ACE inhibitors in both primary and secondary pulmonary hypertension. However the effect of ACE inhibitors in mitral stenosis is not documented. The authors report three patients with severe mitral stenosis in whom surgery was delayed. They had initial symptomatic improvement with diuretics and sodium restriction, but had recurrence of their symptoms while on treatment. Enalapril not only relieved their symptoms in particular exertional dyspnoea and haemoptysis but prevented recurrence and improved their effort tolerance without causing excessive fall of blood pressure or impairment of renal function.

ACE inhibitors are important therapeutic agents in controlling hypertension, correcting some of its pathophysiological derangement and improving its prognosis. While there are many such agents, there may be some important differences between them. This placebo run-in, double blind, crossover study, using 24-hour ambulatory blood pressure monitoring, compares the efficacy of perindopril 4-8 mg and enalapril 10-20 mg as once daily antihypertensive agents on 32 patients. For diastolic blood pressure (DBP), perindopril had a placebo-corrected peak (P) reduction of blood pressure (BP) of -6.4 +/- 1.3 mmHg vs its placebo-corrected trough (T) of -5.2 +/- 1.7 mmHg. Enalapril had a reduction in DBP of -8.5 +/- 1.3 mmHg (P) and -5.7 +/- 1.7 mmHg (T). For systolic blood pressure (SBP), perindopril had a reduction of -7.5 +/- 1.6 mmHg (P) vs -7.3 +/- 2.2 mmHg (T) compared to enalapril with -10.8 +/- 1.6 mmHg (P) vs -8.3 +/- 2.3 mmHg (T). Placebo-corrected trough-to-peak ratio (SBP/DBP) for perindopril was 0.97/0.81 vs 0.77/0.67 for enalapril. There was no difference noted in 24-hour mean BP, area under the curve or post-dose casual BP measurements. Both perindopril and enalapril were well tolerated and the two treatment groups had similar safety profiles. Perindopril thus had a predictable and sustained blood pressure effect giving a 24-hour cover for the patient without excessive peak effect or poor trough effect.

First-dose response to angiotensin-converting enzyme inhibition in congestive cardiac failure: a Malaysian experience

Navookarasu NT, Rahman AR, Abdullah I

Int J Clin Pract, 1999 Jan-Feb;53(1):25-30.
PMID: 10344062

Despite their proven value in reducing morbidity and mortality in different grades of heart failure, angiotensin converting enzyme (ACE) inhibitors continue to be underused. One reason for this is clinicians' apprehension of first-dose hypotension. We conducted a double-blind, randomised, placebo-controlled parallel group study to investigate the effect of various ACE inhibitors on first-dose hypotension. Eighty unselected patients were randomised into five treatment groups: placebo, captopril 6.25 mg, enalapril 2.5 mg, perindopril 2 mg and lisinopril 2.5 mg. Blood pressure was measured at baseline, half hourly for two hours and hourly for three hours after drug treatment. The maximum drops in mean arterial pressure (in mmHg +/- SD) were placebo 5.89 +/- 2.65, perindopril 5.29 +/- 2.49, enalapril 13.28 +/- 3.31, lisinopril 15.04 +/- 5.74 and captopril 16.76 +/- 5.74 (all p < 0.05 vs placebo except for perindopril). Perindopril, unlike the other ACE inhibitors studied, did not produce first-dose hypotension following its initiation in patients with congestive heart failure.

RAS Genetic Variants in Interaction with ACE Inhibitors Drugs Influences Essential Hypertension Control

Heidari F, Vasudevan R, Mohd Ali SZ, Ismail P, Arkani M

Arch Med Res, 2017 Jan;48(1):88-95.
PMID: 28577874 DOI: 10.1016/j.arcmed.2017.03.003

BACKGROUNDS AND AIMS: Essential Hypertension (EH) is a common disorder associated with increased cardiovascular morbidity and mortality in Malaysia. To investigate how genetic polymorphisms of the renin-angiotensin-aldosterone system (RAS) influence EH control with angiotensin-converting enzyme inhibitor drugs (ACEI).
METHODS: A case-control, cross-sectional population-based nested study (n = 142) included hypertensive subjects treated with ACEI drugs, either lisinopril or enalapril (20 mg, once daily) as monotherapy for 24 weeks. In total seven possible polymorphisms of RAS genes were genotyped. The association between those polymorphisms and the changes in blood pressure were observed in the 24 week treatment.
RESULTS: Statistically significant associations of I, G, T, M and G alleles of ACE (I/D, G2350A), AGT (M235T, T175M and G-6A) respectively were observed in essential hypertensive subjects. The decrease in systolic blood pressure and diastolic blood pressure after 24 weeks of treatment of the patients carrying II, GG, and TT genotypes were greater than the groups carrying DD, AA, MM, MM and GG of I/D, G2350A, M235T, T174M and G-6A genotypes respectively. In contrast, No significant difference was observed between renin gene polymorphisms (Bg/I and MboI) and hypertensives.
CONCLUSIONS: Although this study shows a possible association of polymorphisms of RAS genes with the risk of non-control of HT in ACEI-treated patients and indicates the importance of all this system's components in regulating HT, it needs to be replicated in other data sources.

Fulltext Dual blockade of the renin-angiotensin-aldosterone system is safe and effective in reducing albuminuria in Asian type 2 diabetic patients with nephropathy

PMID: 20358155

INTRODUCTION: Blockade of the renin-angiotensin-aldosterone system (RAAS) by either the angiotensin converting enzyme inhibitor (ACE-I) or the angiotensin II receptor blocker (ARB) has been shown to reduce albuminuria and delay the progression of diabetic nephropathy. This study evaluated the effect of dual blockade of the RAAS by adding an ACEI or an ARB to the administration of either drug alone on albuminuria in Asian type 2 diabetic patients with nephropathy.
METHODS: 34 patients were randomly assigned to receive either enalapril 20 mg or losartan 100 mg once daily for eight weeks. Following this, all patients received a combination of enalapril 10 mg and losartan 50 mg daily for eight weeks, followed by enalapril 20 mg and losartan 100 mg daily for another eight weeks. The blood pressure and 24-hour urinary albumin excretion (UAE) were monitored.
RESULTS: Following monotherapy with enalapril, there was a mean and standard error (SE) reduction in the UAE and mean arterial pressure (MAP) of 9.8 (SE 6.8) percent (p-value is 0.061) and 5.3 (SE 2.2) mmHg (p-value is 0.026), respectively; the reduction in UAE and MAP following monotherapy with losartan was by 10.9 (SE 14.1) percent (p-value is 0.053) and 4.5 (SE 1.9) mmHg (p-value is 0.034), respectively. Combination therapy with enalapril and losartan further reduced the UAE (11.2 [SE 8.7] percent, p-value is 0.009] despite there being no significant change in the MAP (-1.2 [SE 1.47] mmHg, p-value is 0.42). The adverse effects included dry cough (seven [19.4 percent] patients, resulting in the withdrawal of medication in two patients), and transient hyperkalaemia (two [six percent] patients).
CONCLUSION: Dual blockade of the RAAS is safe and effective in reducing albuminuria in Asian type 2 diabetic patients with nephropathy.

Several studies show that the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene has been associated with hypertension in various populations. The present study sought to determine the association of the I/D gene polymorphism among Malay male essential hypertensive subjects in response to ACE inhibitors (enalapril and lisinopril).

Fulltext Pattern of potential drug-drug interactions in diabetic out-patients in a tertiary care teaching hospital in Nepal

Dinesh KU, Subish P, Pranaya M, Shankar PR, Anil SK, Durga B

Med J Malaysia, 2007 Oct;62(4):294-8.
PMID: 18551932

A prospective study was conducted at Manipal Teaching Hospital, Pokhara, Nepal to identify and analyze the pattern of the potential DDIs (drug-drug interaction) in diabetes patients. A total of 182 patients who were prescribed 685 drugs (average, 3.76 drugs per prescription) were enrolled. Patients 51 to 60 years of age had a higher risk [43 patients, or (23.6%)] of developing DDIs. It was found that 174 (92.1%) of the potential DDIs were of "moderate" severity. Cardiovascular drugs carried a risk of DDIs (187 drugs, or 49.5%). The most common potential DDI observed was between metformin and enalapril (n = 64).
