Sepsis-induced cardiomyopathy (SIC), which is a common morbid condition, occurs in patients with severe sepsis and septic shock. The clinical characterization of SIC has been largely concept-driven. Heart function has traditionally been evaluated according to two basic conceptual models: a hydraulic pump system, whereby the output from the heart is entirely dependent on its input, or a hemodynamic pump, whereby the cardiac output is a function of preload, global ventricular performance, and afterload. Minimal attention has been given to the intrinsic contractile function of the heart or to the interaction between the peripheral circulation and the intrinsic myocardial function in sepsis. Currently, SIC is assumed to be the result of the interaction of microorganisms that activate the physiopathological pathways and cellular signaling mechanisms that lead to intrinsic myocardial dysfunction. However, the animal models used to study SIC exhibit multiple limitations. This review addresses the conceptual background, historical perspectives, physiologic mechanisms, current evidence, and limitations of SIC characterization. It also highlights potential future directions for the hemodynamic assessment of the intrinsic contractile function of the heart to overcome current methodological limitations. Finally, the present review recommends the exploration of additional potential mechanisms underlying SIC.

“…Although echocardiography is a more frequent method because of it is safe, rapid, reliable, and cost-effective for the evaluation of left ventricle size and functions, yet it may be inadequate especially in cases with limited echocardiographic window. [ 21 22 ] However, echocardiographic images can change with the change in probe angle and measurements because they are operator-dependent. [ 23 ] These situations are important for determining asymmetric septal hypertrophy in HT patients.…”

Is the increased septal perfusion the signal of asymmetrical septal hypertrophy?

In this study, we have compared scintigraphic and echocardiographic data in order to investigate whether increased septal perfusion represents asymmetrical septal hypertrophy (ASH), which is a symptom followed in the scintigraphy of myocardial perfusion. The study consists of a total of 186 patients (120 females and 66 males with an average age of 59.45 ± 11.54 years) who had normal myocardial perfusion scintigraphy and echocardiography examinations. Statistical comparison of septal wall thickness measurements obtained from echocardiography and septal-to-lateral wall ratios (S/L ratio) was performed scintigraphically. Left ventricular mass values were obtained as both scintigraphic and echocardiographic data and their correlations were evaluated in order to assess the presence of left ventricular hypertrophy (LVH). In statistical analyses, the values of interventricular septal thickness in diastole (IVSd), left ventricle posterior wall thickness in diastole (LVPWd), left ventricle mass (LVM), and left ventricle mass index (LVMI) were found to be significantly higher in group 2 (S/L ratio >1) compared to group 1 (S/L ratio <1). In addition, S/L ratio is significantly correlated with echocardiographic IVSd, LVPWd, LVM, LVMI, and scintigraphic LVM (rest) values. Furthermore, echocardiographic LVM and LVMI values were significantly correlated with LVM and LVMI values obtained from scintigraphy. It should be known that increased S/L ratio that can be monitored during scintigraphic studies can be an indicator of septal hypertrophy and/or LVH, however, further examination and close follow-ups should be performed in necessary cases.

“…[7] Three dimensional echocardiography is thought to underestimate left ventricular parameters though there has been improvements in measurements using this method however magnetic resonance imaging remains the reference point. [8,9] Poor health seeking behaviour and late presentation for health care has been documented amongst Nigerians [10] and it is not surprising to find that people with newly diagnosed hypertension have significant cardiac morbidities present at the time of diagnosis. [11,12] Based on several guidelines on the use of echocardiography, an indication for echocardiography exists in many of these patients.…”
