Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a promising target for lowering plasma low-density lipoprotein cholesterol and preventing cardiovascular (CV) disease. Whether plasma PCSK9 measured during the acute phase predicts recurrent CV events in patients with acute myocardial infarction (AMI) remains unresolved. Methods and Results: Plasma PCSK9 levels were measured in 1,646 patients with AMI from the China PEACE-Prospective AMI Study at the acute phase. Additionally, 248 patients were resampled and measured at 1 month post-AMI. Associations of acute-phase PCSK9 tertiles with clinical characteristics and recurrent CV events within 1 year were assessed. Female gender (OR 1.94, 95% CI 1.24–3.03), premature coronary heart disease (CHD; OR 2.12, 95% CI 1.37–3.26), higher high-sensitivity C-reactive protein (OR 1.67, 95% CI 1.44–1.95), and higher triglycerides (OR 1.46, 95% CI 1.03–2.09) were associated with higher baseline PCSK9. Plasma PCSK9 levels in the highest tertile (versus lowest) did not have an increased risk of 1-year recurrent CV events in the AMI cohort (HR 0.78, 95% CI 0.52–1.16) or any subgroup. There was also no association between percentage changes in PCSK9 over the first month and 1-year recurrent events, although there was a trend of differences between patients in the upper versus lower tertiles. Conclusion: Plasma PCSK9 levels measured during the acute phase were associated with high-sensitivity C-reactive protein, triglycerides, premature CHD, and gender in patients with AMI but did not predict recurrent CV events within 1 year. Dynamic changes in PCSK9 suggested a trend yet no significance value in predicting recurrent CV events.

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 : Inflammation plays a role in the development and progression of coronary artery disease (CAD), with circulating markers of vascular inflammation being used in risk assessment including high sensitivity C-reactive protein (hsCRP) and lipoprotein-associated phospholipase A 2 (LpPLA 2 ). While hsCRP responds to the systemic inflammatory stimulus of acute myocardial infarction (AMI), LpPLA 2 has been proposed to be more vascular-specific and to vary minimally based upon clinical presentation. To test this hypothesis, we evaluated both biomarkers among CAD patients presenting with stable angina (SA), unstable angina (USA) or acute myocardial infarction (AMI). Methods : LpPLA 2 (PLAC TM test, diaDexus, Inc.) and hsCRP were measured from samples donated by consenting patients (N=1,010) enrolled in the registry of the Intermountain Heart Collaborative Study that underwent angiographic evaluation for CAD. Patients were categorized by presentation status (SA=637; USA=205; and AMI=168), stratified according to median levels of LpPLA 2 (350.2 ng/mL) and hsCRP above and below 3 mgl/L and followed for 7.5 ± 2.4 years for CAD death. Results : Age averaged 64 ± 12 years and 70% were male. While median hsCRP (mg/L) levels differed significantly by presentation [2.86, 2.80, and 13.7 for SA, USA, and AMI, respectively (p<0.0001)], median LpPLA 2 (ng/mL) levels [350.2, 353.1, and 348.1 for SA, USA, and AMI, respectively (p=0.67)], did not. LpPLA 2 was not only a better predictor of CAD death among the entire cohort (LpPLA 2 : adjusted Hazard Ratio [HR]= 1.47, p=0.04; hsCRP: adjusted HR=0.95, p=0.81), it was a better predictor among patients presenting with AMI (LpPLA 2 : adjusted HR3 1.80, p=0.30; hsCRP adjusted HR=0.76, p=0.63). Conclusions : Among CAD patients, LpPLA 2 varies minimally among differing presentations compared to hsCRP and is a better a predictor of CAD death among those presenting with AMI. This information supports the hypothesis that LpPLA 2 is a vascular specific marker of inflammation and independent of transient systemic inflammatory effects.
