Organ congestion upstream of the dysfunctional left and/or right ventricle, with preserved stroke volume, is the most frequkeywordent feature of myocardial failure.Clinical manifestations do not necessarily correlate with the degree of left ventricular systolic dysfunction (i.e. left ventricular ejection fraction).Systolic and/or diastolic dysfunction may be present, with systolic dysfunction usually predominating.Pulmonary oedema is related to left ventricular diastolic dysfunction. Compensatory mechanisms (within the heart and/or periphery) may prove paradoxically disadvantageous on ventricular stroke work and stroke volume.

Sepsis And Septic Shock

Background: Left ventricular systolic dysfunction (LVSD) and LV diastolic dysfunction (LVDD) are commonly seen in severe sepsis and septic shock; however, their role in patients with concurrent invasive mechanical ventilation (IMV) is less well defined. Methods: This was a prospective observational study on all patients admitted to all the intensive care units (ICUs) at Mayo Clinic, Rochester from August 2007 to January 2009. All adult patients with severe sepsis and septic shock and concurrent IMV without prior heart failure underwent transthoracic echocardiography within 24 hours. Patients with active pregnancy, prior congenital or valvular heart disease, and prosthetic cardiac valves were excluded. Left ventricular systolic dysfunction was defined as LV ejection fraction (LVEF) <50% and LVDD as E/e′ >15. Primary outcome was hospital mortality, and secondary outcomes included IMV duration, ICU length of stay (LOS), and total LOS. Two-tailed P value of <.05 was considered statistically significant. Results: In a total of 106 patients, 58 (54.7%) met our inclusion criteria, with 17 (29.3%), 11 (19.0%), and 5 (8.6%) having LVSD, LVDD, and both, respectively. The cohorts with and without LVSD and LVDD did not differ significantly in their baseline characteristics and laboratory and ventilatory parameters. Compared to those without LVSD, patients with LVSD had higher LV end-systolic diameters but were not different in their left atrial diameters or E/e′ ratio. Patients with LVDD had a higher E velocity and E/e′ ratio compared to those without LVDD. Hospital mortality was not different in patients with and without LVSD (8 [47%] vs 21 [51%], P = 1.00) and LVDD (8 [73%] vs 21 [45%], P = .18). Secondary outcomes were not different between the 2 groups. Conclusion: Left ventricular systolic or diastolic dysfunction did not influence in-hospital outcomes in patients with severe sepsis and septic shock and concurrent IMV.

Background: Patients diagnosed with hypertension will deteriorate into hypertensive heart disease which is characterized by diastolic dysfunction first followed by systolic dysfunction later in the course of the disease. Diastolic dysfunction of the left ventricle causes an increase in LVEDP as well as in the dimension of the left atrium. P-Wave Terminal Force V1 (PTFV1) which is derived from 12 lead ECG could help diagnose diastolic dysfunction in centers where echocardiography is not available. The purpose of this study was to determine the correlation of PTFV1 on the 12-lead Electrocardiography with diastolic dysfunction in patients diagnosed with hypertension in the outpatient clinic of Cardiac Center Adam Malik General Hospital in Medan. Methods: This is a cross-sectional study conducted from March 2019 until August 2019. Patients with hypertension who met the inclusion criteria were examined electrocardiographically to obtain PTFV1 value. Then echocardiography examination was then performed to assess the grades of diastolic dysfunction and other parameters. Analysis of correlation between PTFV1 values and diastolic dysfunction was then conducted. Results: From the clinical characteristics, there is no difference regarding age, sex , and risk factorsbetween the three diastolic dysfunction groups, while echocardiography characteristic shows more reduced EF in grade III diastolic dysfunction (36.5±7.7). Significant differences in PTFV1 are found among diastolic dysfunction groups. Grade I diastolic dysfunction has PTFV1 value of 23.8 mm.ms, grade II diastolic dysfunction has PTFV1 value of 34.1 mm.ms, and grade III diastolic dysfunction has PTFV1 value of 52.1 mm.ms, Significance of  p value is <0.001. There is a strong correlation between PTFV1 and diastolic dysfunction grade (r = 0.63 (P <0.001)). Cut off point of PTFV1 > 29.8 mm.ms can discriminate patients who have increased LAP with a sensitivity of 84% and specificity of 71%. Conclusions: PTFV1 is a simple screening tool which is widely available and correlate well with left ventricular diastolic dysfunction in patients with hypertension, which makes it a good alternative tool especially in areas where echocardiography is not readily available.
