The Devereux formula [14] was used to calculate the left ventricular mass index (LVMI), as follows: LVMI (g/m 2 ) = LVM (calculated by 0.8 × 1.04 [(IVSd + PWTd + LVDd) 3 − LVDd 3 ] + 0.6)/BSA .LVMI is especially useful in cardiology to assess cardiac adaptation to conditions such as hypertension, obesity, or aortic stenosis. Calculation Formula. The formula to calculate the LV Mass Index is: \[ LVMI = \frac{\text{LV Mass (grams)}}{\text{Body Surface Area (m²)}} \] Where: LV Mass is the measured mass of the left ventricle in grams.LVMi was higher in patients with HFrEF than in those with HFpEF (118 vs. 98; P < 0.001). The rhythm, whether sinus rhythm or AF, did not affect the LVMi in HFrEF patients (118 vs. 117; P = 0.91). In contrast, patients with HFpEF in sinus rhythm had a higher LVMi compared with HFpEF patients with AF (103 vs. 93; P = 0.023) (Tables 5 and 6).
Left ventricular mass index (LVMI) is a parameter used in echocardiography and cardiac MRI. LVMI is calculated using the following equations: LVMI = LVM (left ventricular mass)/body surface area; left ventricular mass = 0.8{1.04[([LVEDD + IVSd +PWd] 3 - . LVMI: Left Ventricular Mass Index (g/m²) LV Mass: Left Ventricular Mass (g) Body Surface Area: Usually derived using renowned methodologies like the Dubois formula or Mosteller formula. Both these approaches utilize an individual’s height and weight to deduce the Body Surface Area. The LVM correlated well with the gestational age, body weight, and BSA. The LVMI correlated well with body weight and BSA. Reference ranges with the mean ± SD, range, and interquartile range were calculated for the LVM and LVMI according to the BSA. A significant gradual increase was observed in a LVM with increasing BSA.
The equation for calculating LVMI was formulated as LVMI=93.85+6.91 (1 SD of blood pressure) −3.09 duration of hypertension.12 In our study, we had included both old and new cases of hypertension in the age group of 35 to 85 years of age. We did not find a significant correlation based on gender and therefore conceived a single model for both .
We assessed LVMI that was collected during annual health examinations in round 1 (2010–2012), round 2 (2013–2014), and round 3 (2015–2016) with 2 allometric scalings, height 2.7, and body surface area, in a cohort of participants with hypertension to identify 6‐year trajectories of LVMI by latent class trajectory modeling.We followed up with participants for . Background— Left ventricular (LV) hypertrophy (LVH) in children is widely defined as a left ventricular mass index (LVMI, g/m2.7) >95th percentile. However, LVMI increases with decreasing height in young children; thus, the 95th percentile LVMI will depend on the height distribution of the reference population. The objective of this study was to compare the .Mistake Tip; Incorrect BSA Calculation: Using outdated or incorrect formulas for BSA can lead to inaccurate results.: Use the Mosteller Formula: This is widely accepted and provides reliable BSA calculations.: Ignoring Gender Differences: Applying the same LV Mass Index reference values to both men and women.: Use Gender-Specific Ranges: Always reference the correct normal .
Left ventricular mass index (LVMI) was calculated using a formula, and participants were divided into tertiles based on their LVMI tertiles. During a median follow-up period of median, 8.9 years . The formula is: LVMI = LV mass / BSA. How to calculate LV mass on echo? LV mass on echocardiography can be calculated using the formula: LV mass = 0.8 * (1.04 * ((LVEDD + IVSd + PWd)^3 - (LVEDD)^3)) + 0.6.
LVMI was calculated using the following equations: LV mass = 0.8 (1.04 [LVID + PWTd + SWTd] 3 – [LVID] 3) + 0.6 g. LVMI = LVM/body surface area. RWT was calculated by dividing the sum of SWTd and PWTd by the LVIDd. According to the ASE/EAE, RWT of 0.22 to 0.42 was regarded as normal.LVMI – Linksventrikulärer Massenindex, in Gramm pro Quadratmeter (g/m²) angegeben. LV-Masse – Linksventrikuläre Masse, im obigen Absatz berechnet, in Gramm (g). BSA – Körperoberfläche, die anhand des Gewichts und der Größe deines Patienten berechnet und in Quadratmeter (m²) angegeben wird.
Figure 1. Calculation of left ventricular mass. mass LV = 1.05 (mass total – mass cavity) LV = left ventricle; 1.05 = mycoardial mass constant. Left ventricular hypertrophy (LVH) A diagnosis of left ventricular hypertrophy is based on total .

GT and LVMI could characterize patients as having a normal LV mass and wall thickness, concentric remodeling, concentric hypertrophy, or eccentric hypertrophy, and the three abnormal groups had . The equation for calculating LVMI was formulated as LVMI=93.85+6.91 (1 SD of blood pressure) −3.09 duration of hypertension. 12 In our study, we had included both old and new cases of hypertension in the age group of 35 to 85 years of age. We did not find a significant correlation based on gender and therefore conceived a single model for . Ejection Fraction (EF) calculated by following formula: (LVEDV – LVESV)/LVEDV × 100. LVMI, PWT, IVST, and RWT were selected for the LV dimension parameters. Peak velocities of the early (E) and late (A) phases of the mitral inflow were also measured and their ratio (E/A) was calculated.The recommended formula for echocardiographic estimation of LVM uses linear measurements and is based on the assumption of the left ventricle as a prolate ellipsoid of revolution. . adding complexity to the calculation of LVMi. The most commonly used formula for computing BSA—the Dubois and Dubois regression (BSA = 0.007184 x weight(Kg) 0. .
Remember that LV Mass (LVM) is a formula that your ultrasound machine will calculate for you, once you enter the measurements needed to complete the formula. You do not need to worry about the actual formula but for all you curious folks here it is: LVM(g) = 0.8 x 1.04 x [(IVSd + LVd + PWd) 3 – LVd 3] + 0.6g. Helpful Hints: Altogether, a cutoff level of 150 g/m 2 seems appropriate for LVMI measured with the leading-edge–to–leading-edge convention and the Troy formula, corresponding to 131 g/m 2 measured with the Penn convention and the modified cube formula. 15 Left ventricular mass by both conventions correlates well with left ventricular mass determined at . LVM indexed to body surface area (LVMI) and MWT were significantly higher at TTE compared with MRI (105 g/m 2 ± 48 vs 78 g/m 2 ± 36, P < .001 and 14 mm ± 4 vs 13 . (LVMI) calculated using the Mosteller formula . Papillary muscles were excluded from LVM.surface area (LVMI) calculated using the Mosteller formula (14). Papillary muscles were excluded from LVM. LV end-diastolic MWT was visually assessed and was measured on short-axis cine SSFP images at the thickest segment perpen-dicular to the LV long axis (Fig 1, ). LVH at cardiac MRI B was defined as LVMI greater than 72 g/m 2 in men and greater
