Article: Can quantitative regional myocardial dynamics contribute to the differential diagnosis of acute stress cardiomyopathy?
[show abstract] [hide abstract]
ABSTRACT: Acute stress-induced cardiomyopathy has excessive sympathetic stimulation, microvascular dysfunction similar to hypertension. Regional prominence of left ventricular (LV) septal base and stress-induced LV hypercontractility are the particular features of both acute and chronic stress-related conditions. Novel imaging methods have shown that stress-induced cavity dilation and myocardial wall abnormalities can be a reflection of underlying previous exaggerated hypertensive episodes due to sympathetic overdrive, which results in microvascular dysfunction. Hypertension-mediated chronic stress due to increased after load episodes is possibly the main reason for blunted LV myocardial wall motion capability in patients with stress-related exaggerated hypertension. In this short report, we discussed the interrelation of myocardial dynamics and stress-induced exaggerated hypertension episodes. In addition, quantitative echocardiographic methods which previously were used for description of particular features including LV regional dynamics in hypertensive heart disease can be an option in differential diagnosis of potential cases of acute stress-induced cardiomyopathy.Anadolu kardiyoloji dergisi: AKD = the Anatolian journal of cardiology 02/2012; 12(1):71-4. · 0.44 Impact Factor -
Article: Stress induced hypertensive response: should it be evaluated more carefully?
[show abstract] [hide abstract]
ABSTRACT: Various diagnostic methods have been used to evaluate hypertensive patients under physical and pharmacological stress. Several studies have shown that exercise hypertension has an independent, adverse impact on outcome; however, other prognostic studies have shown that exercise hypertension is a favorable prognostic indicator and associated with good outcome. Exercise hypertension may be encountered as a warning signal of hypertension at rest and future hypertensive left ventricular hypertrophy. The results of diagnostic stress tests support that hypertensive response to exercise is frequently associated with high rate-pressure product in hypertensives. In addition to the observations on high rate-pressure product and enhanced ventricular contractility in patients with hypertension, evaluation of myocardial contractility by Doppler tissue imaging has shown hyperdynamic myocardial function under pharmacological stress. These recent quantitative data in hypertensives suggest that hyperdynamic myocardial function and high rate-pressure product response to stress may be related to exaggerated hypertension, which may have more importance than that it has been already given in clinical practice.Cardiovascular Ultrasound 08/2011; 9:22. · 1.26 Impact Factor
