Letter by Di Bella et al Regarding Article, “Effect of Combined Systolic and Diastolic Functional Parameter Assessment for Differentiation of Cardiac Amyloidosis From Other Causes of Concentric Left Ventricular Hypertrophy”

Objective: Prehypertensive individuals are at increased risk for developing hypertension and their complication. Many studies show that 2/3 prehypertensive individuals develop hypertension after 4 years. ECG and echocardiography are the routine tests used to assess LV mass. The objective of the research to determine the percentage of change in left ventricular morphology in the ECG, echocardiography, which explore the characteristics of left ventricular structural changes by echocardiography in pre-hypertensive subjects. Materials and method: We studied a total of 50 prehypertensive, 30 males (60%) and 20 females (40%), mean age 48.20±8.47years. 50 normotensive volunteers as control participants. These subjects were examined for ECG and echocardiography. Results: In prehypertensive group, with 18% of left ventricular hypertrophy on electrocardiogram, 12% of left ventricular hypertrophy on echocardiography; in the control group, we did not find any subjects with left ventricular hypertrophy. In the group with left ventricular hypertrophy, mostly eccentric left ventricular hypertrophy (83.33%), concentric left ventricular hypertrophy is 16.67%. Restructuring of left ventricular concentric for 15.9% of subjects without left ventricular hypertrophy on echocardiography. Conclusion: There have been changed in left ventricular morphology even in prehypertensive

Different Types

Among the different types, immunoglobulin light chain (AL) cardiac amyloidosis is associated with the highest morbidity and mortality. The outcome, however, is significantly better when an early diagnosis is made and treatment initiated promptly. We present a case of cardiac amyloidosis with left ventricular hypertrophy criteria on the electrocardiogram. After 9 months of follow-up, the patient developed low voltage in the limb leads, while still maintaining the Cornell criteria for left ventricular hypertrophy as well. The relative apical sparing by the disease process, as well as decreased cancellation of the opposing left ventricular walls could be responsible for this phenomenon. The discordance between the voltage in the frontal leads and precordial leads, when present in conjunction with other findings, may be helpful in raising the clinical suspicion of cardiac amyloidosis.
