A polymorphism in the cytochrome P450 3A CYP3A5 enzyme has been implicated in BP (blood pressure) control and arterial hypertension. Carriers of the CYP3A5*1 allele had high, whereas homozygous carriers of the CYP3A5*3 allele exhibit low, CYP3A5 expression in the kidney, where CYP3A5 represents the major CYP3A enzyme. The aim of the present study was to investigate the association of the CYP3A5*1 allele with BP, arterial hypertension, LVM [(left ventricular) mass] and LV geometry in a large Caucasian-population-based cohort. We compared BP, LVM and the prevalence of hypertension between carriers (CYP3A5*1/*1 and CYP3A5*1/*3 genotypes) and non-carriers (CYP3A5*3/*3 genotype) of the CYP3A5*1 allele in the echocardiographic substudy of the third MONICA (MONItoring trends and determinants in CArdiovascular disease) Augsburg survey. After exclusion of 269 individuals who were taking antihypertensive medication, 530 women and 554 men were available for analysis, revealing allele frequencies of 5.8 and 94.2% for the CYP3A5*1 and CYP3A5*3 alleles respectively. Overall, the presence of the CYP3A5*1 allele exhibited no effect on systolic or diastolic BP in either gender. One-third of the individuals in this cohort were hypertensive (BP ≥140/90 mmHg), and the genotype distribution between normotensive and hypertensive individuals revealed no association between CYP3A5*1 and hypertension after adjustment for age, BMI and gender (odds ratio, 1.02; P=0.92). Moreover, no effect of CYP3A5*1 on LVM, thickness of the septal and posterior wall and LV end-diastolic diameter was found. We conclude that CYP3A5*1 exhibits no significant effect on BP, LVM and LV geometry in the KORA/MONICA echocardiographic substudy.

Ventricular Mass

Abstract: Left ventricular hypertrophy (LVH) is target organ damage of cardiac with high prevalence in patients with hypertension. Increase of left ventricular mass was caused by increase in wall thickness as compensatory mechanism to minimize wall stress in response to elevated blood pressure. Left Ventricular Mass Index (LVMI) is one of echocardiography parameters used to diagnose LVH. The purpose of this study is to know the correlation between blood pressure and LVMI in patients with hypertension. A cross sectional study was performed at Cardiac Vascular and Brain Centre/ Central General Hospital of Prof. Dr. R. D Kandou. Sample was determined with consecutive sampling. Blood pressure of subjects were measurement and LVMI were taken from medical record. Data were analyzed used SPSS 21. Fifty one subjects, including 34 subjects with adequate blood pressure control and 17 subjects with inadequate blood pressure control are enrolled with ≥60 years old and men (64.7%) mostly found in this study. Pearson Correlation Test found a positive and significant correlation between systolic blood pressure and LVMI (r=0.488;p<0.05) while Spearman Correlation Test found a positive but not significant correlation between diastolic blood pressure and LVMI (r=0.226;p>0.05). In conclusion, there is a positive correlation between blood pressure and LVMI in patients with hypertension but a significant correlation was just found between systolic blood pressure and LVMI.Keywords: hypertension, Left ventricular hypertrophy (LVH), blood pressure, echocardiography, left ventricular mass index (LVMI)Abstrak: Hipertrofi ventrikel kiri (Left Ventricular Hypertrophy= LVH) merupakan kerusakan target organ jantung dengan prevalensi yang tinggi pada penderita hipertensi. Peningkatan massa ventrikel kiri disebabkan oleh penebalan dinding ventrikel kiri sebagai mekanisme kompensasi untuk meminimalkan tegangan dinding akibat respon terhadap peningkatan tekanan darah. Indeks massa ventrikel kiri (Left Ventricular Mass Index= LVMI) merupakan salah satu parameter ekokardiografi yang digunakan dalam mendiagnosa LVH. Tujuan dari penelitian ini adalah mengetahui korelasi antara tekanan darah dan LVMI pada penderita hipertensi. Penelitian dengan desain potong lintang dilakukan di instalasi pusat jantung dan pembuluh darah RSUP Prof Dr. R. D. Kandou. Sampel ditentukan secara consecutive sampling. Pengukuran tekanan darah dilakukan pada subyek penelitian dan LVMI diperoleh dari rekam medik. Data dianalisa menggunakan SPSS 21. Sebanyak 51 subyek penelitian, termasuk 34 subyek dengan hipertensi terkontrol dan 17 subyek dengan hipertensi tidak terkontrol, terdaftar pada penelitian ini dengan usia ≥60 tahun (39,2%) dan pria (64,7%)paling banyak ditemukan.Uji Korelasi Pearson menemukan tekanan darah sistolik mempunyai korelasi positif dan signifikan dengan LVMI (r=0,488;p<0,05) sedangkan uji Korelasi Spearman menemukan korelasi yang positif namun tidak signifikan antara tekanan darah diastolik dan LVMI (r=0,226;p>0,05). kesimpulan dari penelitian ini adalah terdapat korelasi positif antara tekanan darah dan LVMI pada penderita hipertensi, namun hubungan yang signifikan hanya ditemukan antara tekanan darah sistolik dan LVMI.Kata Kunci : hipertensi, hipertrofi ventrikel kiri, tekanan darah, ekokardiografi, indeks massa ventrikel kiri

Obesity Indices

The aims of this study were to investigate the association between different obesity indices and left ventricular mass (LVM) and to develop interventions for obese hypertensive patients to delay the progression of left ventricular hypertrophy (LVH). The association between the visceral adiposity index (VAI) and LVM was explored using multiple regression analysis in all subjects (n = 1,035), the subgroups of patients aged < 65 (n = 713) and ≥65 years (n = 322), and perimenopausal women (n = 319). The VAI was the only obesity index associated with LVH (OR = 1.134; 95% CI 1.025–1.254, p = 0.015). In the subgroup of patients aged < 65 years, both systolic blood pressure and VAI were risk factors for LVH. However, in the subgroup aged ≥65 years, only systolic blood pressure was a risk factor, and there was no association between VAI and LVH (p = 0.13). Perimenopause was an independent risk factor (OR = 1.786; 95% CI 1.125–2.837, p = 0.014). Reducing the VAI rather than the BMI or waist circumference may prevent LVH complications in obese hypertensive patients. For patients aged < 65 years strict control of blood pressure and obesity may be important, and for those aged ≥65 years blood pressure control should be the priority. Estrogen replacement may be useful in postmenopausal women to prevent LVH.
