Conflicting results are reported about daytime variation on mortality and cardiac outcomes after non-cardiac surgeries. In this cohort study, we evaluate whether the period of the day in which ...surgeries are performed may influence all-cause mortality and cardiovascular outcomes in patients undergoing non-cardiac arterial vascular procedures.
1,267 patients who underwent non-cardiac arterial vascular surgeries between 2012 and 2018 were prospectively included in our cohort and categorized into two groups: morning (7 a.m. to 12 a.m., 79%) and afternoon/night (12:01 p.m. to 6:59 a.m. in the next day, 21%) surgeries. Primary endpoint was all-cause mortality within 30 days and one year. Secondary endpoints were the incidence of perioperative myocardial injury/infarction (PMI), and the incidence of major adverse cardiac events (MACE, including acute myocardial infarction, acute heart failure, arrhythmias, cardiovascular death) at hospital discharge.
After adjusting for confounders in the multivariable Cox proportional regression, all-cause mortality rates at 30 days and one year were higher among those who underwent surgery in the afternoon/night (aHR 1.6 95%CI 1.1-2.3, P = 0.015 and aHR 1.7 95%CI 1.3-2.2, P < 0.001, respectively). Afternoon/night patients had higher incidence of PMI (aHR 1.4 95%CI 1.1-1.7, P < 0.001). There was no significant difference in the incidence of MACE (aHR 1.3 95%CI 0.9-1.7, P = 0.074).
In patients undergoing arterial vascular surgery, being operated in the afternoon/night was independently associated with increased all-cause mortality rates and incidence of perioperative myocardial injury/infarction.
Perioperative cardiovascular guidelines endorse functional capacity estimation, based on ‘cut-off’ daily activities for risk assessment and climbing two flights of stairs to approximate 4 metabolic ...equivalents. We assessed the association between self-reported functional capacity and postoperative cardiac events.
Consecutive patients at elevated cardiovascular risk undergoing in-patient noncardiac surgery were included in this predefined secondary analysis. Self-reported ability to walk up two flights of stairs was extracted from electronic charts. The primary endpoint was a composite of cardiac death and cardiac events at 30 days. Secondary endpoints included the same composite at 1 yr, all-cause mortality, and myocardial injury.
Among the 4560 patients, mean (standard deviation) age 73 (SD 8 yr) yr, classified as American Society of Anesthesiologists physical status ≥3 in 61% (n=2786/4560), the 30-day and 1-yr incidences of major adverse cardiac events were 5.7% (258/4560) and 11.2% (509/4560), respectively. Functional capacity less than two flights of stairs was associated with the 30-day composite endpoint (adjusted hazard ratio 1.63, 95% confidence interval CI 1.23–2.15) and all other endpoints. The addition of functional capacity information to the revised cardiac risk index (RCRI) significantly improved risk classification (functional capacity plus RCRI vs RCRI: net reclassification improvement NRIEvents 6.2 95% CI 3.6–9.9, NRINonevents19.2 95% CI 18.1–20.0).
In patients at high cardiovascular risk undergoing noncardiac surgery, self-reported functional capacity less than two flights of stairs was independently associated with major adverse cardiac events and all-cause mortality at 30 days and 1 yr. The addition of self-reported functional capacity to surgical and clinical risk improved risk classification.

Highlights ► Nearly 50% of patients with acute coronary syndromes (ACS) after noncardiac surgery have evidence of coronary plaque rupture. ► The only independent predictor of plaque rupture in ...coronary angiography was having the diagnosis of ACS. ► ACS after non-cardiac surgery and spontaneous ACS have similar pathophysiology.
•Patients with isolated right-sided fungal endocarditis had better survival.•Heart failure/medical treatment only were related to death in Candida endocarditis.•Isolated right-sided endocarditis a ...less harmful illness in Candida endocarditis.
To compare the clinical and epidemiological features, treatments, and outcomes of patients with isolated right-sided and left-sided fungal endocarditis and to determine the risk factors for in-hospital mortality in patients with Candida sp endocarditis.
A retrospective review of all consecutive cases of fungal endocarditis from five hospitals was performed. Clinical features were compared between patients with isolated right-sided and left-sided endocarditis. In the subgroup of fungal endocarditis due to Candida species, binary logistic regression analysis was performed to determine variables related to in-hospital mortality.
Seventy-eight patients with fungal endocarditis were studied. Their median age was 50 years; 55% were male and 19 patients (24%) had isolated right-sided endocarditis. Overall, cardiac surgery was performed in 46 patients (59%), and in-hospital mortality was 54%. Compared to patients with left-side fungal endocarditis, patients with isolated right-sided endocarditis had lower mortality (32% vs. 61%; p=0.025) and were less often submitted to cardiac surgery (37% vs. 66%; p=0.024). The most frequent etiology was Candida spp (85%). In this subgroup, acute heart failure (odds ratio 5.0; p=0.027) and exclusive medical treatment (odds ratio 11.1; p=0.004) were independent predictors of in-hospital death, whereas isolated right-sided endocarditis was related to a lower risk of mortality (odds ratio 0.13; p=0.023).
Patients with isolated right-sided fungal endocarditis have particular clinical and epidemiological features. They were submitted to cardiac surgery less often and had better survival than patients with left-sided fungal endocarditis. Isolated right-sided endocarditis was also a marker of a less harmful illness in the subgroup of Candida sp endocarditis.
•Studies reporting the etiology of prosthetic valve endocarditis (PVE) are an unmet clinical need.•A prospective cohort study was performed along with a literature review to describe the distribution ...of the etiology of PVE.•At >120days after valve surgery, there is a decrease in the incidence of resistant microorganisms.•PVE occurring at >120days after surgery may be treated with the same empirical treatment as for late PVE.•This approach could lead to higher antibiotic efficacy and less damage to the patient’s natural flora.
To determine the annual incidence of prosthetic valve endocarditis (PVE) and to evaluate its current classification based on the epidemiological distribution of agents identified and their sensitivity profiles.
Consecutive cases of PVE occurring within the first year of valve surgery during the period 1997–2014 were included in this prospective cohort study. Incidence, demographic, clinical, microbiological, and in-hospital mortality data of these PVE patients were recorded.
One hundred and seventy-two cases of PVE were included, and the global annual incidence of PVE was 1.7%. Most PVE cases occurred within 120days after surgery (76.7%). After this period, there was a reduction in resistant microorganisms (64.4% vs. 32.3%, respectively; p=0.007) and an increase in the incidence of Streptococcus spp (1.9% vs. 23.5%; p=0.007). A literature review revealed 646 cases of PVE with an identified etiology, of which 264 (41%) were caused by coagulase-negative staphylococci and 43 (7%) by Streptococcus spp. This is in agreement with the current study findings.
Most PVE cases occurred within 120days after valve surgery, and the same etiological agents were identified in this period. The current cut-off level of 365days for the classification of early-onset PVE should be revisited.
Highlights • We report four cases of infective endocarditis caused by Granulicatella species. • Subacute symptoms and large vegetations are frequently observed. • The development of heart failure, ...embolism and perivalvular abscess is common.
Background: As infective endocarditis has particular characteristics compared to other infectious diseases, it is not clear if sepsis scores are reported with good accuracy in these patients. The aim ...of this study is to evaluate the accuracy of the qSOFA and SOFA scores to predict mortality in patients with infective endocarditis. Methods: Between January 2010 and June 2019, 867 patients with suspected left-sided endocarditis were evaluated; 517 were included with left-sided infective endocarditis defined as "possible" or "definite" endocarditis, according to the Modified Duke Criteria. ROC curves were constructed to assess the accuracy of qSOFA and SOFA sepsis scores for the prediction of in-hospital mortality. Results: The median age was 57 years, 65% were male, 435 (84%) had pre-existing heart valve disease, and the overall mortality was 28%. The most frequent etiologies were Streptococcus spp. (36%), Enterococcus spp. (10%), and Staphylococcus aureus (9%). The sepsis scores from the ROC curves used to predict in-hospital mortality were qSOFA 0.601 (CI95% 0.522-0.681) and SOFA score 0.679 (CI95% 0.602-0.756). A sub-group analysis in patients with and without pre-existing valve disease for SOFA >= 2 showed ROC curves of 0.627 (CI95% 0.563-0.690) and 0.775 (CI95% 0.594-0.956), respectively. Conclusions: qSOFA and SOFA scores were associated with increased in-hospital mortality in patients with infective endocarditis. However, as accuracy was relatively lower compared to other sites of bacterial infections, we believe that this score May have lower accuracy when predicting the prognosis of patients with IE, because, in this disease, the patient's death May be more frequently linked to valvular and cardiac dysfunction, as well as embolic events, and less frequently directly associated with sepsis.
Worldwide distribution of surgical interventions is unequal. Developed countries account for the majority of surgeries and information about non-cardiac operations in developing countries is scarce. ...The purpose of our study was to describe the epidemiological data of non-cardiac surgeries performed in Brazil in the last years.
This is a retrospective cohort study that investigated the time window from 1995 to 2007. We collected information from DATASUS, a national public health system database. The following variables were studied: number of surgeries, in-hospital expenses, blood transfusion related costs, length of stay and case fatality rates. The results were presented as sum, average and percentage. The trend analysis was performed by linear regression model. There were 32,659,513 non-cardiac surgeries performed in Brazil in thirteen years. An increment of 20.42% was observed in the number of surgeries in this period and nowadays nearly 3 million operations are performed annually. The cost of these procedures has increased tremendously in the last years. The increment of surgical cost was almost 200%. The total expenses related to surgical hospitalizations were more than $10 billion in all these years. The yearly cost of surgical procedures to public health system was more than $1.27 billion for all surgical hospitalizations, and in average, U$445.24 per surgical procedure. The total cost of blood transfusion was near $98 million in all years and annually approximately $10 million were spent in perioperative transfusion. The surgical mortality had an increment of 31.11% in the period. Actually, in 2007, the surgical mortality in Brazil was 1.77%. All the variables had a significant increment along the studied period: r square (r(2)) = 0.447 for the number of surgeries (P = 0.012), r(2) = 0.439 for in-hospital expenses (P = 0.014) and r(2) = 0.907 for surgical mortality (P = 0.0055).
The volume of surgical procedures has increased substantially in Brazil through the past years. The expenditure related to these procedures and its mortality has also increased as the number of operations. Better planning of public health resource and strategies of investment are needed to supply the crescent demand of surgery in Brazil.
