Chemotherapy for TC induces acute alterations in diastolic heart function, paralleled by unfavourable metabolic changes.
Further studies are needed to determine how the observed alterations in heart mass and function evolve over time.
In line with previous observations, we observed that PPARα activation of WT animals led to reduced body weight and substantial alterations in heart weight and function (Zungu et al., 2009).
Although these results should be confirmed by different groups in different settings, it is interesting to mention that this paper opens our eyes to a new concept that platelets may release, over days, exosomes that induce and maintain alterations of heart function in septic patients.

Fortunellin significantly attenuated the score of histopathological alterations and alleviated heart function, accompanied with reduced inflammation and oxidative stress.
It was interestingly shown that PDE5A was upregulated in different models of cardiac disease [15], [21] and that early correction of PDE5 alterations could restore heart function and prevent cardiac hypertrophy [22], [23].
Autonomic function effects manifested as alterations in heart rate and heart rate variability (HRV) have been associated with PM2.5 exposure.
Moreover, our results suggest that alterations in heart rate variability may precede changes in traditional markers of cardiovascular function (i.e. blood pressure) in non-apneic snoring individuals.
