Open in a separate window In absence of Resminostat hydrochloride obstructive coronary artery disease, whether the myocardial injury is definitely secondary to oxygen supply-demand imbalance (Type 2 MI), acute myocarditis, stress cardiomyopathy or cardiac involvement in cytokine release syndrome is a challenging issue. polypharmacotherapy, will be explored. The novel coronavirus type 2 (SARS-CoV-2) illness, which leads to severe acute respiratory syndrome in its most severe forms, has been 1st reported in December 2019 in the Chinese province of Hubei and consequently designated like a pandemic from the World Health Corporation (WHO) on March 11th 2020. Globally, as of 13 January 2021, there have been 90,054,813 confirmed instances of COVID-19, including 1,945,610 deaths, reported to WHO.[1] After the Chinese outbreak, Europe overtook China with the highest number of reported instances and deaths. The pandemic now is propagating across Americas, where over 25,958,213 instances and 717,028 deaths has been reported in November 2020.[1] The case-fatality rate (CFR, i.e., number of deaths/quantity of diagnosed instances) differ significantly around the world, showing improved prevalence with improving age. In particular, the CFR is definitely 1% for individuals 50 years of age, 1.3% for 50-year-old individuals, 3.6% for 60-year-old individuals, 8% for 70-year-old individuals, and 14.8% for octogenarians. [2] A number of important comorbidities are associated with worse medical results and CFR in individuals with COVID-19. While CFR in individuals with no medical history is definitely low (0.9%), it raises to 5%-10% when frailty conditions are present [10.5% for cardiovascular disease (CVD), 7.3% for diabetes mellitus (DM), 6.3% for chronic obstructive pulmonary disease, 6% for arterial hypertension, and 5.6% for cancer].[2] Among the predictors of outcome, age offers consistently been reported as an independent and strong covariate associated with mortality.[3] Focusing on seniors patients, a recent cohort study of Resminostat hydrochloride nursing home residents with COVID-19 offers found impaired cognitive physical function as self-employed predictors of mortality with this population.[4] COVID-19 AND CARDIOVASCULAR SYSTEM A number of studies suggest an association between pre-existing CVD and severe COVID-19,[3,5-7] but the viral infection prospects itself to CV complications or exacerbation of pre-existing CVD.[6,7] particularly in the geriatric population.[8] PATHOPHYSIOLOGY COVID-19 and Cardiovascular System: Hypothesis of Interaction and Mechanisms of Damage COVID-19 interacts with various systems, becoming responsible for a broad spectrum of clinical manifestations. Angiotensin transforming enzyme-2 Rabbit polyclonal to ABCA13 (ACE2) has been demonstrated to be the SARS-CoV-2 cell access receptor, after activation of the viral surface spike protein S by transmembrane protease serine 2 (TMPRSS2).[9] ACE2 Resminostat hydrochloride is highly indicated in the lung (principally type II alveolar cells), but has also been found in multiple tissues, including heart, intestinal epithelium, vascular endothelium and kidneys.[6] Relevantly, by cleaving angiotensin II (Ang II), ACE2 produces Ang 1-7, which counteracts the pro-inflammatory and pro-oxidant effects of Ang II.[10,11] Beyond direct cell damage due to viral infiltration, SARS-CoV-2 seems to downregulate ACE 2 expression and Ang 1-7 production, leading to increased levels of Ang II.[12] Consequently, alveolar apoptosis and fibrosis together with cytokine storm and systemic inflammation can result in acute respiratory distress syndrome (ARDS) and multiorgan dysfunction.[13] Cardiovascular complications are often observed in individuals with COVID-19, especially those with severe manifestations. The mechanisms of cardiac injury remain under investigation, but it has been supposed to involve three possible mechanisms: direct myocardial illness through ACE2 receptors indicated in myocardial cells, indirect injury due to the systemic inflammatory response and improved cardiac stress due to hypoxemia (Number 1).[14-16] Open in a separate window Figure 1 Possible mechanisms of cardiovascular injury due to COVID-19. ACE-2: angiotensin transforming enzyme-2; ACS: acute coronary syndrome; AHF: acute heart failure; Ang II: angiotensin II; ARDS: acute respiratory distress syndrome; CS: cardiogenic shock; NF-kB: nuclear element kappa-light-chain-enhancer of triggered B cells; SARS-CoV-2: severe acute respiratory syndrome coronavirus 2; VTE: venous thromboembolism. Evidence suggests that ACE2 takes on a double part in cardiovascular complication of COVID-19. First, ACE2 is largely indicated by myocardial pericytes, [17] consequently representing a potential portal of viral access, resulting in cellular death and swelling. On the other hand, viral replication seems to induce ACE2 downregulation.[18] This may alter the ACE/ACE2 balance leading to hyperactivation of the ACE/Ang II/AT1 system, responsible of vasoconstrictive, pro-inflammatory and pro-oxidant effects, potentially culminating in acute heart failure, endothelial dysfunction and intravascular coagulopathy.[19] The cardiovascular damage mediated by SARS-CoV-2 can also result from the immune-mediated pathway caused by activated T and B cells, leading to a cytokine storm (we.e., interleukin-1 (IL-1), IL-6, Resminostat hydrochloride and TNF-a)[20] that can exert a negative inotropic effect, promote cardiomyocyte.
