Background and Aims: Among the various biomarkers, high sensitivity C-Reactive Protein (hs-CRP) has been widely studied and is easy to use in the prognostication of patients with acute ST elevation myocardial infarction (STEMI). This study aimed to associate serum level of hs-CRP with in-hospital mortality in patients presented with acute STEMI. Methods: This was a hospital-based prospective observational study conducted in Shahid Gangalal National Heart Centre among patients presented to the emergency department with chest pain of less than 24 hours duration, who were diagnosed subsequently to have STEMI. Patients who had known chronic inflammatory diseases, septic foci and chest pain of over 24 hours were excluded from the study. Blood sample for Hs-CRP was sent from the emergency department and was measured with Finecare TM FIA system; Model number: FS-112. The study was conducted from April 2019 to March 2020. Patient outcomes were stratified as per the four groups of serum level of hs-CRP and among them the relationship between mortality and hs-CRP level was tested with chi-square test. The p-value across the groups was again tested for inter-group significance using the Bonferroni adjusted significance level. Results: 140 patients (112 males and 28 females) with mean age of 58.1±14.86 years were enrolled in the study. There was no increased in-hospital mortality in acute STEMI patients who had serum level of hs-CRP below 3 mg/l. In-hospital mortality showed an increasing trend above this level but it reached statistical significance beyond 10 mg/l only. Thirty five percent of our patients of acute STEMI were found to have serum level of hs-CRP above this threshold. The total in-hospital mortality was 13 (9.28%). Conclusion: The increased serum level of hs-CRP was associated with increased in-hospital mortality in patients with acute STEMI.

Background: The natural history of acute myocardial infarction (AMI) as the most prevalent public health issue in Iran has changed with the introduction of novel therapeutic strategies that have reduced its mortality significantly. Major depressive disorder (MDD) is a prevalent and disabling psychiatric disorder and frequently co-exist with AMI. There are proposed pathophysiological links between the two diseases among which inflammation is the most important. With more patients surviving a myocardial infarction (MI) event, post-MI depression has become an important determinant of disability and mortality. Materials and Methods: In this study we defined a 1-month post-MI depressive scale of 200 patients using Beck’s inventory questionnaire II and measured serum high Sensitivity C-Reactive Protein (hs-CRP) and carotid intima-media thickness (CIMT) to look for the association between inflammatory state and atherosclerosis in different depression score categories. Results: Minimum and maximum Beck scores were 1 and 43, respectively with a mean of 13±8. The mean CIMT was 0.77±0.26 mm. Serum hs-CRP level was measured with a mean of 1.51±1.6 mg/L. According to BDI-II scores, 44.2% of patients 1-month post-MI suffered from more than mild depression. Being affected was not correlated with either the level of hs-CRP or CIMT. Nearly 44 percent of patients suffered more than mild depression. There was a negative association between serum hs-CRP level and CIMT as a measure of atherosclerosis in groups of depressed versus non-depressed patients. This may indicate that the extent of atherosclerosis is not correlated with the inflammatory state after MI in depressed versus non-depressed patients. Conclusions: The results of this study indicate that the extent of atherosclerosis is not correlated with the inflammatory state after MI in depressed versus non-depressed patients. Nonetheless, the prognostic indications of increased hs-CRP and depression after AMI remains to be investigated further. [GMJ.2021;10:e1512]

INTRODUCTION Implantation of bare metal or drug eluting stents supported by dual antiplatelet therapy (DAPT) is standard treatment for the management of patients with ST elevation myocardial infarction (STEMI). Individual response to aspirin and clopidogrel is heterogeneous, and decreased response is associated with thrombotic events following stenting. We postulated that systemic inflammation at the time of STEMI would diminish responsiveness to DAPT. The aim of this study is to evaluate the correlation between elevated high-sensitivity C-reactive protein (hs-CRP) as a marker of inflammation and decreased platelet sensitivity to DAPT in STEMI. METHODS We recruited patients with STEMI undergoing percutaneous coronary intervention (PCI) who received oral clopidogrel 600 mg loading dose followed by 75 mg daily maintenance dose and aspirin 325 mg daily. Platelet reactivity and hs-CRP were measured within 72 hours of PCI and at 6 weeks. For patients receiving eptifibatide, blood samples were taken 48 hours after discontinuation. Platelet reactivity was assessed using the VerifyNow platelet function analyzer. A cut-off value of 208 platelet reaction units (PRU) was used to define high on-clopidogrel platelet reactivity (HCPR) and a value of 454 aspirin reaction units (ARU) was used to define high on-aspirin platelet reactivity (HAPR). RESULTS In 20 patients aged 31 to 85, in hospital and 6 weeks after STEMI, hs-CRP was 6.7 (SD 4.0) and 2.6 (SD 3.2) respectively, p< 0.01. Changes in ARU from 408.3 (SD 54.3) to 425.2 (SD 68.2) and PRU from 157.8 (SD 74.7) to 164.2 (SD 75) were not statistically significant. 2 patients had HAPR in hospital; 1 became sensitive at follow up. 2 patients developed HAPR and HCPR. We saw a trend towards higher PRU in diabetic patients and those prescribed statins. CONCLUSIONS Although we found a significant difference in hs-CRP levels between the first and second time point, no significant difference was found in on-aspirin and on-clopidogrel platelet reactivity between the time points.Thus, in this small series, the acute inflammatory state associated with STEMI did not appear to influence the on-DAPT reactivity at the dosages used. Trends among those with diabetics and prescribed statins will be discussed

Background. Accumulating evidence suggests that inflammation plays a key role in acute kidney injury (AKI) pathogenesis. We explored the relationship between high-sensitivity C-reactive protein (hs-CRP) and AKI in acute myocardial infarction (AMI). Methods. We prospectively included 2,063 AMI patients in whom hs-CRP was measured at admission. AKI incidence and a clinical composite of in-hospital death, cardiogenic shock, and acute pulmonary edema were the study endpoints. Results. Two-hundred-thirty-four (11%) patients developed AKI. hs-CRP levels were higher in AKI patients (45 ± 87 vs. 16 ± 41 mg/L; p < 0.0001). The incidence and severity of AKI, as well as the rate of the composite endpoint, increased in parallel with hs-CRP quartiles (p for trend <0.0001 for all comparisons). A significant correlation was found between hs-CRP and the maximal increase of serum creatinine (R = 0.23; p < 0.0001). The AUC of hs-CRP for AKI prediction was 0.69 (p < 0.001). At reclassification analysis, addition of hs-CRP allowed to properly reclassify 14% of patients when added to creatinine and 8% of patients when added to a clinical model. Conclusions. In AMI, admission hs-CRP is closely associated with AKI development and severity, and with in-hospital outcomes. Future research should focus on whether prophylactic renal strategies in patients with high hs-CRP might prevent AKI and improve outcome.

ObjectiveWe investigated whether serum high-sensitivity C reactive protein (hs-CRP) levels measured in an emergency department (ED) are associated with inhospital mortality in patients with cardiovascular disease (CVD).DesignA retrospective cohort study.SettingED of a teaching hospital in Japan.Participants12 211 patients with CVD aged ≥18 years who presented to the ED by an ambulance between 1 February 2006 and 30 September 2014 were evaluated.Main outcome measuresInhospital mortality.Results1156 patients had died. The inhospital mortality increased significantly with the hs-CRP levels (<3.0 mg/L: 7.0%, 95% CI 6.4 to 7.6; 3.1–5.4 mg/L: 9.6%, 95% CI 7.9 to 11.3: 5.5–11.5 mg/L: 11.2%, 95% CI 9.4 to 13.0; 11.6–33.2 mg/L: 12.3%, 95% CI 10.5 to 14.1 and ≥33.3 mg/L: 19.9%, 95% CI 17.6 to 22.2). The age-adjusted and sex-adjusted HR for total mortality was increased significantly in the three ≥5.5 mg/L groups compared with the <3.0 mg/L group (5.5–11.5 mg/L: HR=1.32, 95% CI 1.09 to 1.60, p=0.005; 11.6–33.2 mg/L: HR=1.38, 95% CI 1.14 to 1.65, p=0.001 and ≥33.3 mg/L: HR=2.15, 95% CI 1.84 to 2.51, p<0.001). Similar findings were observed for the CVD subtypes of acute myocardial infarction, heart failure, cerebral infarction and intracerebral haemorrhage. This association remained unchanged even after adjustment for age, sex and white cell count and withstood Bonferroni adjustment for multiple testing. When the causes of death were divided into primary CVD and non-CVD deaths, the association between initial hs-CRP levels and mortality remained significant, but the influence of hs-CRP levels was greater in non-CVD deaths than CVD deaths. The percentage of non-CVD deaths increased with hs-CRP levels; among the patients with hs-CRP levels ≥33.3 mg/L, non-CVD deaths accounted for 37.5% of total deaths.ConclusionOur findings suggest that increased hs-CRP is a significant risk factor for inhospital mortality among patients with CVD in an ED. Particular attention should be given to our finding that non-CVD death is a major cause of death among patients with CVD with higher hs-CRP levels.

Abstract Background High-sensitivity C-reactive protein (hs-CRP) elevation frequently occurs in acute myocardial infarction (AMI) and is associated with adverse outcomes. Since diabetes mellitus (DM) is characterized by an underlying chronic inflammation, hs-CRP may have a different prognostic power in AMI patients with and without DM. Methods We prospectively included 2064 AMI patients; hs-CRP was measured at hospital admission. Patients were grouped according to hs-CRP quartiles and DM status. The primary endpoint was a composite of in-hospital mortality, cardiogenic shock, and acute pulmonary edema. Two-year all-cause mortality was the secondary endpoint. Results Twenty-six percent (n = 548) of patients had DM and they had higher hs-CRP levels than non-DM patients (5.32 vs. 3.24 mg/L; P < 0.0001). The primary endpoint incidence in the overall population (7%, 9%, 13%, 22%; P for trend < 0.0001), in DM (14%, 9%, 21%, 27%; P = 0.0001), and non-DM (5%, 8%, 10%, 19%; P < 0.0001) patients increased in parallel with hs-CRP quartiles. The adjusted risk of the primary endpoint increased in parallel with hs-CRP quartiles in DM and non-DM patients but this relationship was less evident in DM patients. In the overall population, the adjusted OR of the primary endpoint associated with an hs-CRP value ≥ 2 mg/L was 2.10 (95% CI 1.46-3.00). For the same risk, hs-CRP was 7 and 2 mg/L in patients with and without DM. A similar behavior was observed for the secondary endpoint when the HR associated with an hs-CRP value ≥ 2 mg/L found in the overall population was 2.25 (95% CI 1.57-3.22). For the same risk, hs-CRP was 8 and 1.5 mg/L in DM and non-DM patients. Conclusions This study shows that hs-CRP predicts in-hospital outcome and two-year mortality in AMI patients with and without DM. However, in DM patients, the same risk of developing events as in non-DM patients is associated to higher hs-CRP levels.

Background: Inflammatory biomarkers are associated with adverse cardiovascular events during ST-elevation acute myocardial infarction (STEMI). We aimed to investigate the role of inflammatory biomarkers, high-sensitivity C-reactive protein (hs-CRP), and soluble ST-2 (sST2), for prediction of adverse cardiovascular events in STEMI. Methods: This was a prospective cohort study that consecutively enrolled patients with STEMI. Subjects were observed during hospitalization until discharge or fatal events happened. Adverse cardiovascular event was a compilation of cardiac mortality, acute heart failure, cardiogenic shock, reinfarction, and malignant ventricular arrhythmia. Blood samples were withdrawn on admission and inflammatory biomarkers (hs-CRP and sST2) were measured. The receiver operator characteristics curve and multivariable analysis were performed to determine which inflammatory biomarkers predict in-hospital adverse cardiovascular events and mortality. Result: Of 166 subjects, the in-hospital adverse cardiovascular events occurred in 41 subjects (24.6%) and mortality occurred in 16 subjects (9.6%). Subjects with in-hospital adverse cardiovascular events and mortality had a significantly higher hs-CRP level, but comparable sST2 level than subjects without events. The hs-CRP level was the most precise biomarkers to predict in-hospital adverse cardiovascular events (hs-CRP cut-off ≥2.75 mg/L) and mortality (hs-CRP cut-off ≥7 mg/L). Multivariable analysis indicated hs-CRP ≥2.75 mg/L as an independent predictor for in-hospital adverse cardiovascular events (adjusted odds ratio [OR]: 2.79, 95% confidence interval [CI]: 1.05-7.39, P = .039) and hs-CRP ≥7 mg/L for mortality (adjusted OR: 5.45, 95% CI: 1.13-26.18, P = .034) in STEMI. Conclusion: On admission, hs-CRP level independently predicted in-hospital adverse cardiovascular events, at cut-off level ≥2.75 mg/L, and mortality, at cut-off level ≥7 mg/L, in STEMI patients.

Background: Elevated hs-CRP is associated with worse cardiovascular outcomes in patients with acute myocardial infarction (AMI), but little is known about predictors of elevated hs-CRP after AMI. Methods: TRIUMPH and VIRGO are prospective AMI registries that assessed hs-CRP levels 30 days after AMI. TRIUMPH assessed hs-CRP levels at 6 months. Multivariable regression analysis was conducted to examine predictors of elevated hs-CRP [≥2.0 mg/L] at 30 days and at 6 months after an AMI (TRIUMPH only). Results: Of 3410 patients in both registries, 58.6% had elevated hs-CRP 30 days post AMI. Patients with elevated hs-CRP were more likely to be female, black, obese, smokers, to have had higher LDL-C at the time of their AMI, with more peripheral vascular disease and history of heart failure, and were less likely to have had a prior PCI (Table). In TRIUMPH, baseline hs-CRP ≥2 mg/L (n=1301) was significantly associated with elevated hs-CRP at 6 months (p<0.001). Patients with elevated hs-CRP at 6 months (n=407) were more likely to be black, obese, smokers, have peripheral vascular disease and have higher baseline hs-CRP. Conclusions: hs-CRP remains elevated in a large proportion of patients following AMI. We identified several predictors of elevated hs-CRP at 1 and 6 months post AMI. Further studies are needed to validate the findings and understand the utility of routine screening of hs-CRP in post AMI patients.
