ABSTRACT

A 67-year-old woman presented to the emergency department for a simple partial seizure of her left upper and lower limbs that lasted for 1 hour and ultimately resolved before her presentation. She had no history of coronary artery disease, and her neurological exam was normal. Five hours later, she complained of chest pain. An electrocardiogram showed ST segment elevation in the lateral leads, and her troponin level was increased. She was diagnosed with takotsubo cardiomyopathy. This case reflects the brain-heart connection and is the first reported case of takotsubo cardiomyopathy following a simple partial seizure.

ABSTRACT

Coronary stent thrombosis is a life-threatening condition induced by multiple factors, including allergic reactions. A 64-year-old man presented with stent thrombosis in the left anterior descending artery and multiple cardiorespiratory arrests immediately after the first dose of the BNT162b1 mRNA vaccine. He underwent emergent percutaneous coronary intervention. Anaphylaxis-induced stent thrombosis, or type III Kounis syndrome, is a highly possible diagnosis. Cardiogenic shock can hide the skin manifestations of anaphylaxis, making this syndrome challenging to diagnose. This clinical case underscores the importance of surveillance for at least 30 minutes after vaccine administration, especially in patients at risk.

ABSTRACT

A 72-year-old woman undergoing percutaneous intervention to a calcified proximal left anterior descending (LAD) coronary artery lesion using Shockwave Intravascular Lithotripsy (S-IVL) developed new atrial flutter. She then returned to sinus rhythm after treatment with amiodarone. S-IVL can cause cardiomyocyte depolarization. We hypothesize that pacing can occur during atrial repolarization, inducing supraventricular tachyarrhythmias and even triggering atrial macro re-entrant circuits. We recommend synchronizing shock wave delivery with R waves on the electrocardiogram to lower the risk of arrhythmias.

ABSTRACT

OBJECTIVE: Describe a mechanical method of perforation-dilatation of the pulmonary valve in pulmonary atresia with intact interventricular septum (PA-IVS), with or without stenting the patent ductus arteriosus (PDA) and medium-term results. METHOD: Since 2007, all patients with PA-IVS and a right ventricle adequate for biventricular repair, benefited from a transcatheter attempt to perforate-dilate the valve with or without stenting the PDA, and were included in this retrospective study. TECHNIQUE: A catheter was percutaneously introduced through the femoral vein and positionned in front of the atretic pulmonary valve. A lasso catheter was introduced through the femoral artery to the other side of the pulmonary valve. The tip of a rigid guidewire was then pushed through the atretic valve and taken with the lasso, creating a loop that allowed for balloon valvuloplasty. If the child remained ductal dependant following PGE1 withdrawal, a stent is placed in the ductus arteriosus. RESULTS: Five patients were included in this series. Four patients were successfully dilated, and two patients necessitated stents. The procedure had to be interrupted in one patient. FOLLOW-UP: One patient with a patent stent was operated at the age of one year and died in the postoperative period. The other patient with a stent is now 16 months old with a patent stent and an oxygen saturation of 98%. The two remaining patients without stent are now 3- and 18-month-old with oxygen saturation of 85% and 96% respectively. CONCLUSION: The percutaneous treatment of PA-IVS is feasible and avoids early high risk surgery. Stenting the ductus arteriosus may replace a Blalock shunt. However, the prognosis is still related to the severity of the anomaly.

ABSTRACT

BACKGROUND AND AIM: The effect of ezetimibe-statin combination on inflammatory markers in acute coronary syndrome is unknown. The aim of our study is to evaluate the effect of this combination on the lipid profile, the CRP hs and the sCD40 ligand levels in acute coronary syndrome (ACS) patients. METHODS: This is a randomized, double-blind study including 93 patients admitted for ACS randomized in 2 groups, ezetimibe 10 mg + atorvastatin 10 mg vs atorvastatin 20 mg + placebo, for 12 weeks follow-up; blood samples were collected for lipid profile, ALT, AST, CRP and sCD40L at baseline, 12 hours, 4 weeks, and 12 weeks. RESULTS: There was no significant difference in total cholesterol levels, HDL, LDL, CRP, but there was a significant decrease in sCD40L levels in the ezetimibe combination group, with less side effects in the combination group, mainly myalgia (p = 0.012). CONCLUSION: Ezetimibe combination with low dose statin in patients in acute coronary syndrome could be a safe, potent therapy to reduce LDL level with antiinflammatory effect.

ABSTRACT

Secretory phospholipase A2 (sPLA2) is an enzyme that plays an important role in the pathogenesis of atherosclerosis and of adverse cardiovascular events. It is currently the target of emerging therapeutic agents. Our study was designed to investigate the effect of aggressive lowering of low-density lipoprotein (LDL) cholesterol with ezetimibe and atorvastatin on sPLA2 activity. We randomized 100 patients with stable coronary artery disease (CAD) or CAD equivalent (diabetes, stroke, or peripheral vascular disease) to receive ezetimibe 10 mg/day in association with atorvastatin 40 mg/day (combination therapy group) versus atorvastatin 40 mg/day and placebo (monotherapy group). Patients on statin therapy before inclusion were allowed to enter the study as long as the potency of the statin was lower than atorvastatin 40 mg/day. Lipid profile, high-sensitivity C-reactive protein (hs-CRP), and sPLA activity were measured at baseline and after 8 weeks of therapy. The decrease in LDL cholesterol was more significant in the combination therapy group, but the decrease in hs-CRP was similar. sPLA2 activity significantly decreased in the ezetimibe/atorvastatin group from 29 U/ml (interquartile range 23 to 35) to 26 U/ml (23 to 29, p = 0.001) but remained similar in the placebo/atorvastatin group (23 U/ml, 19 to 32, vs 22 U/ml, 19 to 28, p = NS). In a multivariate stepwise linear regression model, change in sPLA2 correlated with change in hs-CRP (p <0.001), baseline LDL cholesterol level (p = 0.001), body mass index (p = 0.003), diabetes mellitus (p = 0.04) and combination therapy with ezetimibe/atorvastatin (p = 0.05). In conclusion, this study demonstrates that coadministration of ezetimibe and atorvastatin decreases sPLA2 activity.

ABSTRACT

Ezetimibe is effective in providing additional low-density lipoprotein (LDL) cholesterol lowering when coadministered with statins, but its effect beyond LDL cholesterol lowering is unknown. Oxidized LDL (ox-LDL) is a better predictor of adverse cardiovascular events than standard lipid parameters. The objective of this study was to investigate the effect of ezetimibe on ox-LDL. A total of 100 patients with coronary artery disease or coronary artery disease equivalent were randomized to atorvastatin 40 mg/day and ezetimibe 10 mg/day or to atorvastatin 40 mg/day and placebo. LDL cholesterol, LDL cholesterol subfractions, and ox-LDL were measured at baseline and after 8 weeks of therapy. The ezetimibe group had a larger reduction in total LDL cholesterol compared to placebo. This was due mainly to a larger reduction in large buoyant LDL (24% vs 10%, p = 0.008). Ox-LDL level did not change in the placebo group (50 +/- 13 vs 51 +/- 13 U/L), while it decreased in the ezetimibe group, from 51 +/- 13 to 46 +/- 10 U/L (p = 0.01 vs baseline and p = 0.02 vs final level in placebo). The change in ox-LDL correlated significantly with those in total LDL and in large buoyant LDL (r = 0.6 and r = 0.5, respectively, p <0.01 for both), but not with that of small dense LDL, high-density lipoprotein, or very low density lipoprotein. In conclusion, this study demonstrates that ezetimibe decreases ox-LDL cholesterol through reductions in total LDL cholesterol and in large buoyant LDL cholesterol.

ABSTRACT

BACKGROUND: Tirofiban at the bolus dose of 10 microg/kg does not suppress the inflammatory response following percutaneous coronary intervention (PCI). This may be due to less than optimal inhibition of platelet aggregation. High bolus dose tirofiban (25 microg/kg) allows better inhibition of platelet aggregation but its anti-inflammatory effect remains unknown. HYPOTHESIS: High bolus dose tirofiban exhibits anti-inflammatory activity. METHODS: A total of 100 patients referred for PCI were randomized to receive high bolus dose tirofiban followed by a 24-h infusion or a bolus and an infusion of saline. Patients with elevated troponin or with thrombus in the culprit lesion were excluded. Inflammatory markers were measured at baseline and at 24 h. RESULTS: Levels of soluble CD40 ligand (sCD40L) were not affected by PCI while those of interleukin-6 (IL-6) and of high sensitivity C-reactive protein (hs-CRP) significantly increased. Despite inhibiting platelet's aggregation by > 90%, tirofiban did not suppress the rise of IL-6 and hs-CRP. Median (interquartile range) elevation of IL-6 was 0.6 pg/mL (-1.5-3.6) versus 0.4 pg/mL (-0.7-1.8) and that of hs-CRP was 2.1 mg/L (0.7-5.2) versus 2.4 mg/L (1-4.7) in the tirofiban and the control groups, respectively (p = ns). However, in patients with diabetes mellitus, tirofiban significantly suppressed the rise of hs-CRP by 65% (p = 0.01), but did not significantly affect the rise of IL-6. CONCLUSION: In low-risk patients undergoing PCI, tirofiban did not attenuate the rise of inflammatory markers. However, the significant effect in diabetics suggests that tirofiban may have anti-inflammatory activity in higher risk patients.

ABSTRACT

OBJECTIVE: The primary endpoint of this prospective clinical study is to ascertain the degree of blood pressure control in the early-morning hours after 8 weeks of treatment with Telmisartan in hypertensive patients using home blood pressure measurements. METHODS: Two hundred forty Lebanese patients with uncontrolled hypertension are enrolled in the study. The blood pressure is measured at the initial visit, then at week 4 of follow-up (optional visit) and after the 8 weeks period, by the physician at his office (with pulse rate) and by the patient at home in the morning. RESULTS: The blood pressure measured by the patient at home in the morning has a mean value of 129.7/79.1 mmHg, significantly less than 135/85 mmHg (P < 10(-1)), and it is reduced by 31.9/13.5 mmHg (P < 10(-5)). At the physician's office, the reduction is 34.8/16 mmHg (P < 10(-4)). Heart rate is decreased by 4.7+/-0.5 bpm (P < 10(-5)). The drug was well tolerated. CONCLUSION: This study has demonstrated that Telmisartan, by his long half-life, protects the patients against the early-morning hours blood pressure surge, period during which coronary and cerebral events are the most frequent.

ABSTRACT

OBJECTIVE: The study was designed to examine the effect of percutaneous coronary intervention (PCI) on adiponectin and leptin levels. We have previously demonstrated that PCI triggers a systemic inflammatory response. We hypothesized that inflammation participates in the pathogenesis of diabetes mellitus and the metabolic syndrome by modulating levels of adiponectin and leptin. DESIGN: Prospective study in which inflammation was induced by PCI. PATIENTS: Forty-eight patients with stable coronary artery disease and without diabetes mellitus. MEASUREMENTS: High-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), leptin and adiponectin were measured at baseline and 48 h after the procedure. RESULTS: Following PCI, hs-CRP increased by 211%, IL-6 by 87% and leptin by 19%, while adiponectin decreased by 14% (P < 0.001 for all). The change in IL-6 correlated with that in hs-CRP (rho = 0.32; P = 0.027), as did the changes in IL-6 and leptin (rho = 0.31; P = 0.03). The change in adiponectin, however, did not correlate with the change in any of the other markers. CONCLUSION: This study demonstrates that PCI affects the levels of adiponectin and leptin within 48 h. These effects may be secondary to the inflammatory response triggered by PCI.

ABSTRACT

This study assessed the effects of tirofiban and statins on high-sensitivity C-reactive protein, interleukin-6, and soluble CD40 ligand after percutaneous coronary intervention in patients who had stable coronary artery disease. Tirofiban insignificantly limited the increase of soluble CD40 ligand after revascularization, especially in patients who had high levels of this marker at baseline (p = 0.06), whereas statins significantly inhibited increases in interleukin-6 and, to a lesser extent, high-sensitivity C-reactive protein without affecting the soluble CD40 ligand.

ABSTRACT

BACKGROUND: In the setting of acute myocardial infarction (AMI), several investigators have demonstrated that emergency coronary angioplasty (PTCA) reduces in-hospital mortality of primary cardiogenic shock (CS) from 90% to less than 50% ; however, few studies have focused on the current outcome of non selected patients in whom the onset of AMI is immediately complicated by CS. PURPOSE OF THE STUDY: To evaluate in-hospital mortality of the patients admitted to our institution for Q wave AMI presented in CS. MATERIAL AND METHOD: Between 05/93 and 05/03, 30 consecutive pts, 26 men and 4 women, in CS following AMI were treated with direct PTCA, 26 without thrombolysis and 4 as rescue after failed streptokinase. AMI was defined by prolonged chest pain and > or =1 mm ST segment elevation in > or =2 contiguous peripheral leads or > or =2 mm for precordial leads on the admission ECG. The diagnosis of CS was based on the combination of systolic blood pressure of <90 mm Hg, unresponsive to volume expansion, signs of acute circulatory failure (cyanosis, cold extremities, restlessness, mental confusion or coma) and congestive heart failure secondary to myocardial dysfunction. In 40% of cases the diagnosis of CS was only clinical and in 60% of cases was confirmed by a Swan Ganz catheter. Mean age was 62.3 +/- 12.3 years, 7 had triple vessel disease, 14 a double vessel disease, 8 a single vessel disease and in one case a left main disease. The AMI was anterior in 22 pts (73%), inferior in 8 (27%). Intraaortic balloon was used in 3 pts, CPR in 16 (47%), transitory pacemaker in 1 pt, inotropes in 25 pts, emergency coronary artery bypass grafting (CABG) in 1 pt. RESULTS: Success for PTCA with a residual stenosis < 50% and a TIMI flow III was obtained in 26 pts (87%). Mean time between CS and revascularization was 219 +/- 302 minutes. 19 pts (63%) survived and 11 pts (37%) died while at the hospital, 6 from intractable shock, 4 from multiple organ failure and in 1 case from pulmonary hemorrhage. Mean time of revascularization for the surviving was 190 +/- 329 min, and for the dead 295 +/- 212 min. Hospital mortality for inferior infarction is 12.5% after successful angioplasty. Comparison of surviving and non surviving number of patients according to revascularization time showed a significant difference of these groups whether the revascularization was accomplished before or after 120 minutes. [table: see text] CONCLUSION: Direct PTCA for AMI immediately complicated by CS, can be achieved with a high success rate, and can significantly reduce in-hospital mortality; this improvement of survival is most evident if revascularizarion is performed early.
