In patients with pulmonary hypertension (PHT), the assessment of left ventricular (LV) diastolic function by echocardiography may not be reliable. PHT can affect Doppler parameters of LV diastolic function such as mitral inflow velocities and mitral annular velocities. The current guidelines for the assessment of LV diastolic function do not recommend specific adjustments for patients with PHT. ⋯ Our study suggests E/average e' may be the only reliable tissue Doppler parameter of LV diastolic dysfunction in patients with PHT, and that septal e' is paradoxically decreased in patients with PHT and normal left-sided filling pressures.

Statins are recommended for secondary prevention. Our aims were to describe the proportion of very elderly patients receiving statins after non-ST segment elevation acute coronary syndrome (NST-ACS) and to determine the prognostic implications of statins use. ⋯ Although most octogenarians presenting a NST-ACS are already on statins before the episode, their LDL cholesterol is frequently >2.6 mmol/L. Octogenarians who do not receive statins have a high-risk profile, with significant frailty and comorbidity.

Non-ST elevation myocardial infarction (NSTEMI) is one of the most common manifestations of acute coronary syndromes (ACS). We evaluated the prognostic role of cardiac troponin I (cTnI) at presentation and peak cardiac troponin I in patients with NSTEMI. ⋯ These findings documented the different prognostic significance of cTnI at presentation and peak cTnI in patients presenting with NSTEMI, and highlighted the importance of monitoring the levels of cTnI in this high-risk population.
