RESUMO

We hereby report a puzzling case of multiple sclerosis (MS) relapse presenting as Takotsubo syndrome (TTS). Female, 42-years old, who presented herself to the Emergency Room of University Hospital "ASST Spedali Civili" of Brescia, Italy, for a severe headache and a non-ST-segment elevation acute coronary syndrome. Coronary angiogram showed no signs of coronary atherosclerosis. Upon further neurological evaluation, a diagnosis of MS relapse, related to TTS, was made, and treatment was started accordingly. The patient was discharged after 12 days after the admission, free of symptoms, and without signs of neurological and cardiological active disease. A hallmark of TTS is its association with a preceding stressful event. It may also be connected to a wide variety of diseases, including neurological ones, such as stroke, intracranial bleeding, head trauma, migraine, and seizures. However, up to our knowledge, only few cases of MS-induced TTS were previously described. Whether it is plausible to consider TTS as an uncommon extra-neurological manifestation of MS is still debated, however all the evidence points in that direction, considering the central role of catecholamines in TTS pathogenesis. With this case report the authors hope to encourage research on this field and on the intricate topic of brain-heart connections.

RESUMO

BACKGROUND AND OBJECTIVES: The complement system plays an important role in the development of acute coronary syndrome (ACS). Complement C1q is an important initial component of the classical complement pathway and closely related to many chronic inflammatory diseases, including atherosclerosis (AS). We aimed to determine whether there was association between serum complement C1q and the severity of coronary stenosis. SUBJECTS AND METHODS: 320 patients who underwent coronary arteriography (CAG) were stratified into non-ACS group (control group, n = 74), unstable angina group (UA group, n = 197) and acute myocardial infarction group (AMI group, n = 49) according to the severity of coronary stenosis and clinical manifestations. The severity of coronary stenosis was represented in Gensini score, and serum complement C1q level was compared using immunity transmission turbidity among three groups. RESULTS: The level of complement C1q in AMI group was lower significantly than control group and UA group (P < 0.05), but there was no correlation between serum complement C1q and Gensini score (ß=-0.086, P = 0.125). In nitrate-taking patients, serum complement C1q had a negative association with Gensini score (r=-0.275, P = 0.001), and in non-smokers, there was also a negative correlation (ß=-0.159, P = 0.036). After calibrating smoking, drinking or statins, the serum complement C1q levels of control group, UA group and AMI group decreased in sequence (P <  0.05). Logistic regression analysis showed that the decreasing of serum complement C1q was an unfavorable factor for acute myocardial infarction (OR=0.984, 95 %CI=0.972∼0.997, P = 0.015) and for ACS (OR=0.984, 95 %CI=0.971∼0.984, P = 0.025) in drinking patients. Regrettably, ROC curve suggested that the accuracy in diagnosing coronary atherosclerotic heart disease by serum complement C1q was low (AUC=0.568, 95 %CI= 0.492-0.644, P = 0.076, sensitivity 73.6 %, specificity 58.1 %). CONCLUSION: Serum complement C1q in ACS patients, in particular AMI patients, showed lower level. This finding suggests further decrease of complement C1q level in ACS patients may be a contributory factor to instability or rupture of atherosclerotic plaques. Combined with other clinical indicators, it can be helpful to predict the risk and severity of coronary stenosis.

RESUMO

Acute coronary syndrome occurring during the course of a type I hypersensitivity reaction constitutes Kounis syndrome. We report a case of a 64-year-old man who presented with a non-ST elevation myocardial infarction and peripheral blood eosinophilia. He had rhinitis and constitutional symptoms for several days prior to presentation. Blood investigations revealed moderate eosinophilia and elevated IgE levels. A cardiac MRI showed generalised oedema with a subtle wall motion abnormality in basal inferior/inferolateral wall, and subendocardial high signal on late gadolinium enhancement suggesting a localised myocardial infarction. A coronary angiogram then revealed triple vessel disease. A diagnosis of Kounis syndrome was made. Within days of starting appropriate treatment, the patient's eosinophil count returned to normal with improvement of clinical picture.

RESUMO

The occurrence of myocardial ischemia and myocardial infarction in pregnancy is relatively rare, the occurrence of myocardial infarction in pregnancy is associated with cardiovascular risk factors. The deficiency of coagulation regulatory systems in the occurrence of venous thrombosis is well established; however, their role in arterial thrombosis is controversial. Here, we present an interesting case of a 34-year-old of acute myocardial syndrome without persistent ST segment elevation, which revealed transient protein S deficiency. Management of acute coronary syndrome (ACS) during pregnancy may represent a unique clinical challenge. In this manuscript, we review the clinical presentation, anatomic considerations, and management strategy in our patient presenting with ACS. Objective: this case highlights the importance of multimodality approach to help to obtain a more timely diagnosis of myocardial infarction in pregnancy and the importance collaboration between obstetricians, cardiologists, pediatricians and anesthesiologists to ensure optimal care.

RESUMO

Acute coronary syndrome (ACS) leads to clinical symptoms such as chest pain, dyspnea, and arrhythmia. The occurrence of ACS is mainly related to the vulnerable plaques in the coronary arteries. MicroRNA-21 (miR-21) is widely expressed in cardiovascular disease and considered as a marker of myocardial infarction, but its role in vulnerable atherosclerotic plaque of ACS is poorly studied. The cases of ACS and control group were selected in 2 years. Our results revealed that miR-21 was highly positively correlated with the maximum lipid core area, the number of diseased vessels, the number of macrophages, the number of vulnerable plaques, and negatively correlated with the thickness of fiber caps. In the high expression group, the number of coronary artery lesions, the number of vulnerable plaques, the core area of lipid pools and the number of macrophages were significantly higher than those in the low expression group and the middle expression group. But the high expression group of the thickness of the fiber cap was significantly lower than that of the low expression group and the medium expression group. These studies show that miR-21 is an important factor leading to vulnerable plaque instability in ACS, and it can be a predictor of acute adverse events in coronary heart disease.

RESUMO

A 54-year-old man suffered a leg cramp while diving in the ocean at a depth of 20 meters. He began to surface, with his ascent based on a decompression table. He lost consciousness at the surface and was rescued by a nearby boat. The boat staff judged him to be in cardiac arrest, so they performed chest compressions. When the boat reached port where an ambulance was waiting, emergency medical technicians confirmed that the patient was in cardiac arrest; his initial rhythm was asystole. Treated with basic life support, the patient was then transported to a rendezvous point, where a physician-staffed helicopter waited. The patient remained in cardiac arrest, so the staff of the helicopter performed tracheal intubation with mechanical ventilation, securing a venous route, infusion of adrenaline, and mechanical chest compression. On arrival at our hospital 100 minutes after collapse, he remained in cardiac arrest. Continued advanced cardiac life support failed to obtain spontaneous circulation. Whole-body computed tomography (CT) at 120 minutes after the collapse showed multiple gas bubbles in the heart, aorta, inferior vena cava, cerebral artery, coronary artery and portal vein with lung edema. This is the first case to show gas in the bilateral coronary arteries on CT. The present case clearly demonstrates that decompression sickness can also induce acute coronary syndrome.

RESUMO

BACKGROUND: Near-infrared spectroscopy (NIRS) intravascular ultrasound imaging can detect lipid-rich plaques (LRPs). LRPs are associated with acute coronary syndromes or myocardial infarction, which can result in revascularisation or cardiac death. In this study, we aimed to establish the relationship between LRPs detected by NIRS-intravascular ultrasound imaging at unstented sites and subsequent coronary events from new culprit lesions. METHODS: In this prospective, cohort study (LRP), patients from 44 medical centres were enrolled in Italy, Latvia, Netherlands, Slovakia, UK, and the USA. Patients with suspected coronary artery disease who underwent cardiac catheterisation with possible ad hoc percutaneous coronary intervention were eligible to be enrolled. Enrolled patients underwent scanning of non-culprit segments using NIRS-intravascular ultrasound imaging. The study had two hierarchal primary hypotheses, patient and plaque, each testing the association between maximum 4 mm Lipid Core Burden Index (maxLCBI4mm) and non-culprit major adverse cardiovascular events (NC-MACE). Enrolled patients with large LRPs (≥250 maxLCBI4mm) and a randomly selected half of patients with small LRPs (<250 maxLCBI4mm) were followed up for 24 months. This study is registered with ClinicalTrials.gov, NCT02033694. FINDINGS: Between Feb 21, 2014, and March 30, 2016, 1563 patients were enrolled. NIRS-intravascular ultrasound device-related events were seen in six (0·4%) patients. 1271 patients (mean age 64 years, SD 10, 883 [69%] men, 388 [31%]women) with analysable maxLCBI4mm were allocated to follow-up. The 2-year cumulative incidence of NC-MACE was 9% (n=103). Both hierarchical primary hypotheses were met. On a patient level, the unadjusted hazard ratio (HR) for NC-MACE was 1·21 (95% CI 1·09-1·35; p=0·0004) for each 100-unit increase maxLCBI4mm) and adjusted HR 1·18 (1·05-1·32; p=0·0043). In patients with a maxLCBI4mm more than 400, the unadjusted HR for NC-MACE was 2·18 (1·48-3·22; p<0·0001) and adjusted HR was 1·89 (1·26-2·83; p=0·0021). At the plaque level, the unadjusted HR was 1·45 (1·30-1·60; p<0·0001) for each 100-unit increase in maxLCBI4mm. For segments with a maxLCBI4mm more than 400, the unadjusted HR for NC-MACE was 4·22 (2·39-7·45; p<0·0001) and adjusted HR was 3·39 (1·85-6·20; p<0·0001). INTERPRETATION: NIRS imaging of non-obstructive territories in patients undergoing cardiac catheterisation and possible percutaneous coronary intervention was safe and can aid in identifying patients and segments at higher risk for subsequent NC-MACE. NIRS-intravascular ultrasound imaging adds to the armamentarium as the first diagnostic tool able to detect vulnerable patients and plaques in clinical practice. FUNDING: Infraredx.

RESUMO

Pulmonary sequestration (PS) is a rare congenital malformation, even more when its arterial supply is a coronary artery. We present a case of a 68-year-old man admitted in the emergency room with an acute coronary syndrome and no evidence of significant coronary disease. Instead, he had an abnormal branch from the circumflex coronary artery nourishing a mass in the left lower pulmonary lobe. A coronary steal phenomenon was proposed to explain the clinical presentation. An anterior left thoracotomy with ligation of the abnormal branch and atypical resection of the lung segment comprising the sequestration was performed.

RESUMO

The Cabrol technique employs a synthetic graft to connect the coronary arteries to an aortic graft in patients with complex disease of the ascending aorta. Acute Cabrol graft thrombosis is a life-threatening situation that presents as acute coronary syndrome, as it leads to acute coronary hypoperfusion. We present a patient with unstable anginal symptoms who had undergone aortic surgery 6 months prior to presentation. Cardiac catheterisation was concerning for aortic dissection yet was later revealed to be acute occlusion of a Cabrol graft. The patient ultimately died of cardiogenic shock. We review the Cabrol technique, complications and management of acute graft thrombosis.

RESUMO

BACKGROUND: Elevated lipoprotein (a) is recognized as a risk factor for incident cardiovascular events in the general population and established cardiovascular disease patients. However, there are conflicting findings on the prognostic utility of elevated lipoprotein (a) level in patients with coronary artery disease (CAD).Thus, we performed a meta-analysis to evaluate the prognostic value of elevated lipoprotein (a) level in CAD patients. METHODS AND RESULTS: A systematic literature search of PubMed and Embase databases was conducted until April 16, 2019. Observational studies reporting the prognostic value of elevated lipoprotein (a) level for cardiac events (cardiac death and acute coronary syndrome), cardiovascular events (death, stroke, acute coronary syndrome or coronary revascularisation), cardiovascular death, and all-cause mortality in CAD patients were included. Pooled multivariable adjusted risk ratio (RR) and 95% confidence interval (CI) for the highest vs. the lowest lipoprotein (a) level were utilized to calculate the prognostic value. Seventeen studies enrolling 283,328 patients were identified. Meta-analysis indicated that elevated lipoprotein (a) level was independently associated with an increased risk of cardiac events (RR 1.78; 95% CI 1.31-2.42) and cardiovascular events (RR 1.29; 95% CI 1.17-1.42) in CAD patients. However, elevated lipoprotein (a) level was not significantly associated with an increased risk of cardiovascular mortality (RR 1.43; 95% CI 0.94-2.18) and all-cause mortality (RR 1.35; 95% CI 0.93-1.95). CONCLUSIONS: Elevated lipoprotein (a) level is an independent predictor of cardiac and cardiovascular events in CAD patients. Measurement of lipoprotein (a) level has potential to improve the risk stratification among patients with CAD.

RESUMO

BACKGROUND The aim of this study was to systematically evaluate the effect of oral Xa inhibitors plus antiplatelet therapy in the treatment of coronary artery disease. MATERIAL AND METHODS All randomized controlled trials (RCTs) about antiplatelet therapy plus Xa factor inhibitors for coronary artery disease from database inception to January 2019 were searched for and collected from PubMed, Embase, and the Cochrane Library. Two reviewers extracted and analyzed the data independently. Additionally, RevMan 5.0 software was applied for meta-analysis. RESULTS Seven RCTs with 50 044 patients were included. The meta-analysis results showed that treatment with antiplatelet therapy plus Xa factor inhibitors in patients with coronary artery disease could significantly reduce the risk of ischemic events (P<0.00001). Besides, risk of all-cause mortality (P=0.003), myocardial infarction (P=0.02) and ischemic stroke (P<0.0001) were also significantly reduced. However, risk of massive hemorrhage after TIMI (P<0.00001), minor hemorrhage after TIMI (P<0.00001), and intracranial hemorrhage (P=0.006) were significantly increased, respectively. Xa inhibition drugs also intended to increase risk of fatal bleeding, but there was no significant difference (P=0.08). CONCLUSIONS Antiplatelet therapy plus Xa factor inhibitors in patients with coronary artery disease was effective, which could reduce the risk of ischemic composite endpoints, all-cause mortality, myocardial infarction, and ischemic stroke. However, it could significantly increase risk of bleeding in terms of safety.

RESUMO

BACKGROUND: An increasing amount of evidence confirms that abnormalities in glucose metabolism are associated with cardiovascular morbidity and mortality in acute coronary syndromes (ACS). The in-hospital management of hyperglycemic diabetic patients with ACS is complex, and the traditional clinical-organizational approaches show a high degree of heterogeneity nationwide in Italy. METHODS: The current survey (March 2016-January 2017), carried out through the Delphi method, was focused on some management issues to verify the modalities/possibilities of resolution in daily clinical practice. In addition to the 12 members of the Board, who defined the web-based questionnaire and coordinated the various stages of the process, 66 specialists, cardiologists or diabetologists, were involved in 6 Italian Regions (Lombardy, Tuscany, Lazio, Friuli-Venezia Giulia, Puglia and Sicily). Three iterative rounds of evaluation of the 24 statements included in the questionnaire were scheduled. For each statement, the median evaluation value and the degree of convergence of the Panel of specialists were determined. RESULTS AND CONCLUSIONS: The final analysis reveals two key aspects with a broad convergence of opinions: (i) the need, since admission to hospital, of a close collaboration between cardiologists and diabetologists in the assistance of high-risk patients; and (ii) the opportunity of a specific diagnostic therapeutic care pathway extended to post-discharge management, where the role of the general practitioner should be adequately emphasized.

RESUMO

PURPOSE: To compare the predictive capacity of the CHA2DS2-VASc and AHEAD scores in predicting acute coronary syndrome (ACS), ischemic stroke (IS), and mortality in patients with heart failure (HF). METHODS: A total of 404,635 patients hospitalized for HF between 2000 and 2011 were recruited from a large national database in Taiwan. The predictive value of both scores was evaluated by analysis of the area under the receiver operating characteristic curve (AUROC), and the difference in their discriminative capacity was assessed using the DeLong test. RESULTS: The AUROC for the CHA2DS2-VASc score was significantly higher than that for the AHEAD score in predicting ACS and IS: 0.53 (95% CI = 0.53-0.54) versus 0.51 (95% CI = 0.51-0.52) for ACS, and 0.57 (95% CI = 0.56-0.57) versus 0.52 (95% CI = 0.51-0.52) for IS, respectively (all DeLong tests p < 0.001). By contrast, for mortality risk, the AUROC was significantly lower for the CHA2DS2-VASc score (0.56, 95% CI = 0.55-0.56) than the AHEAD score (0.60, 95% CI = 0.59-0.60; DeLong test p < 0.001). CONCLUSIONS: The ability of the CHA2DS2-VASc score to predict macrovascular complications (ACS and IS) in HF patients was higher than that of AHEAD.

RESUMO

Treatment of acute coronary syndromes secondary to septic coronary valvular embolism in endocarditis patients remains unclear. Several revascularization strategies have been described, including thromboaspiration, stent implantation, balloon angioplasty, and surgical intervention. We herein present an illustration of an atypical case of an acute coronary syndrome related to a coronary bifurcation occlusion due to a septic embolism in a patient presenting with infective endocarditis. We also summarized previous similar cases and their management.

RESUMO

New-onset atrial fibrillation (NOAF) has been associated with poor outcome in patients with acute coronary syndromes (ACSs). The objective of this study was to investigate the relationship between the development of NOAF and severity of coronary artery disease using the SYNTAX score (SS) and SYNTAX score II (SSII) in patients with non-ST-segment elevation ACS (NSTE-ACS) who were treated with percutaneous coronary intervention (PCI). A total of 662 patients with NSTE-ACS were consecutively enrolled. The incidence of NOAF was 11.4% among the patients with NSTE-ACS. Mean age was significantly higher in NOAF group (P = .011). White blood cell count, peak troponin I, high sensitivity C-reactive protein, uric acid, left atrial volume index, and ratio between early mitral inflow velocity and mitral annular early diastolic velocity were significantly higher in NOAF group (respectively, P = .024, P = .017, P = .002, P = .009, P = .025, P < .001, and P < .001). The hemoglobin, ejection fraction, and post PCI thrombolysis in myocardial infarction grade <3 were significantly lower in NOAF group (P = 001, P = .010, P = .038). The SS and SSII were significantly higher in NOAF group (all P < .001). According to the results of multivariate logistic regression analysis, the SSII was correlated with NOAF (P < .001) in the study groups. We demonstrated that high SSII is significantly associated with NOAF.

RESUMO

Objective Although several clinical trials have shown that the mid- and long-term safety and efficacy of prasugrel are better than those of clopidogrel after percutaneous coronary intervention (PCI), there are few data regarding the short-term safety. Methods In this study, we retrospectively analyzed the short-term (72 hours) PCI-related bleeding complications and mid-term (12 months) efficacy in 250 consecutive coronary artery disease patients who underwent PCI and received aspirin plus prasugrel (prasugrel group; 67.7±10.0 years, 200 men). Patients The comparison group consisted of 250 age- and gender-matched patients who received aspirin plus clopidogrel (clopidogrel group: 67.2±11.2 years, 199 men). Results The incidence of a composite of PCI-related bleeding complications in the acute phase post-PCI was significantly higher in the prasugrel group than in the clopidogrel group (22.4% vs. 13.2%, p=0.007), although the incidence of non-PCI-related bleeding complications over 12 months was comparable between the 2 groups. The cumulative incidence of major cardiovascular events (MACEs) was comparable between the prasugrel and clopidogrel groups (log-rank test; p=0.561). A multivariate logistic regression analysis of the 250 prasugrel-treated patients showed that acute coronary syndrome tended to be negatively associated with the incidence of PCI-related bleeding complications (p=0.061). Conclusion Prasugrel and clopidogrel may have similar efficacy for preventing cardiovascular events as the post-PCI antiplatelet regimen; however, prasugrel should be used cautiously because of the risk of PCI-related bleeding complications.

RESUMO

BACKGROUND: Patients with acute coronary syndrome (ACS) and previous cardiovascular disease (CVD) (stroke, peripheral arterial disease [PAD] or coronary artery disease [CAD]) are at high risk of serious events and mortality. Current clinical guidelines recommend new antiplatelet drugs (NADs) for high cardiovascular risk patients with ACS; however, these drugs are underused in different scenarios. METHODS: This study included 1717 ACS patients from 3 tertiary hospitals. Of them, 641 (37.33%) suffered from previous CVD: 149 patients with stroke, 154 patients with PAD and 541 patients with CAD. Bleeding, mortality and major adverse cardiac events (MACE) at 1 year of follow-up after hospital discharge were analyzed. RESULTS: NADs administration during hospital stay and at discharge was less frequent in patients with previous CVDs (P<0.001, for both). Cox analysis in this cohort of patients showed that clopidogrel prescription at discharge was independently associated with MACEs (HR: 1.59 [95% CI: 1.03-2.45]; P=0.036) and with death (HR: 1.99 [95% CI: 1.00-3.98]; P=0.049) in multivariate analysis. More specifically, when ticagrelor prescription at discharge was compared with clopidogrel, a significant death reduction was found in both, the univariate and the multivariate Cox analysis (HR: 4.54 [95% CI: 2.26-9.13]; P<0.001 and HR: 2.61 [95% CI: 1.16-5.90]; P=0.021, respectively). CONCLUSIONS: New antiplatelet drugs, especially ticagrelor, showed lower rates of mortality in patients with CVD without differences for bleeding. Despite the recommendations of current clinical guidelines for high risk patients with ACS, the use of NADs is very low in "real-life" patients with previous CVD.

RESUMO

INTRODUCTION: Spontaneous coronary artery dissection (SCAD) accounts for up to 4% of acute coronary syndromes (ACS) on coronary angiography and predominantly affects women (>90%). SCAD most often occurs in patients with few or no conventional cardiovascular risk factors. This condition remains underdiagnosed due to a lack of awareness among health-care providers and misdiagnosis on coronary angiography. Areas covered: In this review, authors aim to summarize contemporary data on the etiology, morbidity and mortality risks, as well as management strategies in order to raise awareness. Expert opinion: The last decade of extensive research revealed that SCAD is not as rare as previously thought and needs to be in the differential diagnosis of all MI patients, especially in young to middle-aged women. Predisposing factors, such as fibromuscular dysplasia, and potential triggers like physical or emotional stresses, are frequently linked. Coronary angiography is the first-line diagnostic tool and should be performed meticulously because of more fragile vessel architecture to avoid iatrogenic dissections. If angiographic findings are uncertain, the use of intravascular imaging may be required. Conservative therapy is favored over revascularization unless patients have high-risk features. Recurrent cardiovascular events post-SCAD are frequent, and patients should be closely monitored after a SCAD event.
