During the 1980s and 1990s, improved treatment of hypertension and hyperlipidaemia and more successful management of myocardial infarction may have led to reduced mortality rates due to circulatory diseases, in spite of persistent or even increasing morbidity rates (Molstad and Andersen, 2002).
The increased morbidity and mortality rate prevailing in HCV infection and the increased burden of HCV-related infections have attracted widespread attention, with potential slow evolving characteristics at rapidly progressive signatures causing greater impact on public health [ 10– 13].
However, there is consistency in identifying an intraoperative onset (mainly during CPB) of hyperlactatemia as a determinant of bad outcomes, whereas late hyperlactatemia in the ICU is not associated with an increased morbidity and mortality rate [7].
Contrast-induced nephropathy (CIN) after coronary angiography is associated with increased morbidity and mortality rates.
Two to threefold increased morbidity and mortality rates are reported, especially if generalized tonic clonic seizures (GTCS) occur.
Maintaining homeostasis is of great importance, and acquired electrolyte disorders can occur as a manifestation of poor quality of care during the ICU stay and can result in increased morbidity or mortality rates [43, 44].
Epidemiological studies have confirmed a positive correlation between levels of particulate pollution and increased morbidity and mortality rates among general populations [12], [13].
Therefore, although the burden of infection will increase substantially within infected people which presumably results in increased morbidity and mortality rates, the number of people infected is unlikely to change.
Positive selection to maintain the high frequency of the heterozygotes should also overcome the negative selection imposed by the increased morbidity and mortality rates among the homozygotes and compounded heterozygotes.
