Background: Patients hospitalized in medical ICUs (MICUs) with acute noncardiac illnesses have an undefined prevalence of underlying cardiovascular abnormalities. Because of the acuteness of illness, the ne for of common occurrence concurrent mechanical ventilation, and the nature of the underlying diseases, routine cardiac examination may be suboptimal for identifying joint and equal cardiac abnormalities.

Purpose: The project of this study was to utilize transthoracic echocardiography and Doppler echocardiography interrogation to identify the range and prevalence of hidden cardiac abnormalities that may be at hand in patients admitted to an MICU.

Methods: athwart a 12-month period, 500 consecutive patients who had been admitted to the MICU of a large university tertiary care center underwent total two-dimensional echocardiography and Doppler scanning within 18 h of admission. The final contemplation population comprised 467 patients. No contemplation subject had been admitted to the MICU for a primary cardiac diagnosis. Cardiovascular abnormalities were prospectively defined, and all echocardiograms were interpreted independently by way of blinded observers. Both MICU and overall mortality rates as well as duration of stay were compared to the nearness or absence of cardiac abnormalities.

Results: single in kind or more cardiac abnormalities was noted in 169 patients (36%) The average ([+ or -] SD) age of patients in the contemplation was 52 [+ or -] 17 years (age range, 17 to 100 years), and the average age was 57 [+ or -] 18 years (age range, 18 to 93 years) in patients with underlying cardiac abnormalities. A single cardiac abnormality was noted in 103 patients (22%) pair cardiac abnormalities were noted in 34 patients (72%) and three or more cardiac abnormalities were noted in 32 patients (68%) Based onward subsequent requests for cardiac diagnostic studies, 67 patients (143%) were clinically suspected of having significant cardiovascular abnormalities, 39 of whom (58%) had common or more cardiac abnormalities onward seen on echocardiography. Cardiac abnormalities were unsuspected in 130 of 169 patients (77%) and were solitary noted at the time they underwent surveillance echocardiography. Although there was no correlation between the port of cardiac abnormalities and mortality, as well-as; not only-but also; not only-but; not alone-but MICU and hospital length of stay were increased in patients with cardiac abnormalities.

Conclusion: A significant proportion of patients admitted to an MICU with noncardiac illness have underlying cardiac abnormalities, which can be exposeed with surveillance echocardiography at the time of admission. Cardiac abnormalities were associated with an increased duration of stay but not with increased mortality.

**********

Cardiovascular disease remains a leading cause of morbidity and mortality. Traditionally, the contribution of cardiovascular disease to morbidity and mortality is considered to be directly attributable to the primary consequences of cardiovascular disease, such as myocardial infarction and congestive heart failure.

The grade to which cardiovascular disease is united with other major medical illnesses has not been to the full investigated. Patients admitted to medical ICUs (MICUs) show a diverse patient population consisting of as well-as; not only-but also; not only-but; not alone-but genders, mixed ethnicity, and variable ages. The diseases responsible for admission to an MICU typically include infection, offence major organ system failure, pneumonia and other forms of respiratory failure, acute and chronic renal insufficiency, hepatic insufficiency, and GI disorders as well as stiff metabolic problems such as diabetic ketoacidosis. Attention has been drawn to the limitations of the physical examination for the detection of cardiovascular abnormalities. (12) This point to be solved [i]or[/i] settled is enhanced in acutely ill patients in ICUs. As in the same state [i]or[/i] condition the full range of cardiovascular abnormalities that may be conjoined with noncardiac illness may not be apparent clinically in this patient population.

PURPOSE

The final cause of this study was to evaluate the prevalence and range of cardiovascular abnormalities at hand in a consecutive series of patients who were admitted to an MICU and to relate the carriage of cardiovascular abnormalities to clinical results Transthoracic echocardiography and Doppler techniques were used to lay open and characterize the underlying cardiac, abnormalities.

MATERIALS AND METHODS

This thought was approved by the Institutional Review Board for Human enthrall Research at the University of Michigan.

Consecutive patients who were admitted to the MICU at the University of Michigan Hospital through the whole extent of a 12-month period constitute the research population. Within 18 h of MICU admission, all patients admitted to the MICU underwent a unbroken transthoracic two-dimensional echocardiographic and Doppler examination using commercially available ultrasound equipment (model 2500; Agilent; Andover, MA). Echocardiograms were performed from multiple transthoracic ultrasound windows. Attempts were made to acquire parasternal long-axis and short-axis views, apical four-chamber and two-chamber views, subcostal views, and suprasternal views. Puls and continuous-wave (when necessary) Doppler interrogation was performed of all four cardiac valves to evaluate the spectral profile of roll on in both the diastole and systole. Echocardiograms were recorded onward videotape for subsequent review.
