Insights

Cyclic variation of myocardial-integrated backscatter (CV-IB) shows altered myocardial structure in end-stage renal disease (ESRD) and essential hypertension (EH) patients. CV-IB values were lower in EH patients than controls and ESRD patients, and lower in ESRD patients than controls.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Nephrology

Background:

  • Cyclic variation of myocardial-integrated backscatter (CV-IB) is a non-invasive method for assessing myocardial contractile function.
  • Limited data exists on CV-IB in patients with end-stage renal disease (ESRD).

Purpose of the Study:

  • To investigate and compare CV-IB in essential hypertensive (EH) patients, ESRD patients, and healthy controls.
  • To assess myocardial ultrasonic tissue characteristics using CV-IB.

Main Methods:

  • Compared 40 EH patients, 24 ESRD patients, and 10 healthy controls using 2D-Doppler echocardiography.
  • Analyzed CV-IB at the interventricular septum (IVS) and left ventricular (LV) posterior wall (PW) during systole and diastole.

Main Results:

  • EH patients had significantly higher blood pressure than ESRD patients and controls.
  • Left ventricular mass index (LVMI) was elevated in both EH and ESRD patients compared to controls.
  • CV-IB values were significantly lower in EH patients compared to ESRD patients and controls, and lower in ESRD patients compared to controls.

Conclusions:

  • CV-IB provides valuable parameters for evaluating myocardial structure in EH and ESRD patients.
  • Further research is warranted to fully elucidate the role and implications of CV-IB in ESRD patients.

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
