Introduction. Kounis syndrome is the concurrence of an acute coronary syndrome (ACS) caused by coronary vasospasms, acute myocardial infarctions, or stent thromboses in case of allergic or hypersensitivity reactions. Kounis syndrome is mediated by mast cells that interact with macrophages and T-lymphocytes, causing degranulation and inflammation with cytokine release. It is a life-threatening condition that has many trigger factors and is most commonly caused by medicines. Case Presentation. A 71-year-old male was admitted with a fever of five days’ duration associated with cellulitis, for which he had been treated with clindamycin and flucloxacillin before admission. He was a diagnosed patient with hypertension and dyslipidemia five years ago. After taking the antibiotics, he had developed generalized itching followed by urticaria suggesting an allergic reaction. Therefore, he was admitted to the hospital. After admission, he developed an ischaemic-type chest pain associated with autonomic symptoms and shortness of breath. An immediate ECG was taken that showed ST-segment depressions in the chest leads V4–V6, confirmed by a repeat ECG. Troponin I was 8 ng/mL. Acute management of ACS was started, and prednisolone 10 mg daily dose was given. After complete recovery, the patient was discharged with aspirin, clopidogrel, atorvastatin, metoprolol, losartan, isosorbide mononitrate, and nicorandil. Prednisolone 10 mg daily dose was given for five days after discharge. Conclusion. In immediate hypersensitivity, with persistent cardiovascular instability, Kounis syndrome should be considered, and an electrocardiogram and other appropriate assessments and treatments should be initiated. Prompt management of the allergic reaction and the ACS is vital for a better outcome of Kounis syndrome.

A patient presenting an ST-segment elevation could represent a life-threatening condition in Emergency Department (ED). This case shows how sometimes, a chronic, and more often, an acute abuse of alcohol is related to important harmful effects on myocardial contractility. The authors present a case of a 19-year-old male of oriental-Asiatic origin admitted unconscious to ED with alcoholic fetor: on electrocardiogram a significant and widespread STsegment elevation was observed. A bedside echocardiography showed no abnormalities in segmental kinetics; therefore electrocardiogram- alterations could be related to a coronary spasm. The literature is poor about this effect induced by acute alcohol ingestion: the pathophysiological mechanism at the base of the abnormal muscle contractility, seems to be related to an impairment in cyclic guanosine monophosphate production, although a second and less probable hypothesis could be an altered intracellular concentration of calcium levels.

Background: Kounis syndrome is an allergy-related acute coronary syndrome that is induced by various pharmacological and environmental factors. Given that many clinicians are not aware of this condition, many cases may be underdiagnosed. We report a case of type II Kounis syndrome induced by phloroglucinol.Case Summary: A 52-year-old man with pre-existing coronary artery stenosis presented with a 30-min history of chest pain and erythematous rash after intramuscular administration of phloroglucinol. An electrocardiogram demonstrated ST-segment elevation in leads II, III and aVF. Emergency coronary angiography revealed severe stenosis in the distal right coronary artery. Intravascular ultrasound showed plaque rupture and thrombosis, and the minimum lumen area was 3.0 mm2. A 3.5 × 38 mm stent was implanted in the distal right coronary artery. Troponin I levels were elevated. A diagnosis of type II Kounis syndrome induced by phloroglucinol was made, and the condition manifested as acute ST-segment elevation myocardial infarction.Conclusions: Clinicians should be aware of Kounis syndrome as a possible diagnosis in a patient who presents with chest pain and allergic manifestations given that an increasing number of triggers are being reported.

Kounis syndrome (KS) is defined as acute coronary syndrome (ACS) triggered by mast cell and platelet activation in the setting of allergic or anaphylactic insults. KS is a unique and complex cause of ACS and many cases may be missed due to its highly variable clinical manifestations. In this report, we present a case of KS type I triggered by metamizole in the absence of a previous history of allergy to this drug. Following the administration of metamizole, the patient developed generalized acute urticaria, chest pain and diaphoresis. Electrocardiography (ECG) showed ST-segment elevation suggestive of myocardial infarction complicated by ventricular tachycardia. No coronary disease was observed on coronary angiography. The cardiac manifestations of KS may be life-threatening, and so it is important to appropriately recognize and treat this condition.

Life-threatening anaphylaxis is a systemic hypersensitivity reaction that may be allergic or non-allergic. Kounis syndrome is an acute coronary syndrome caused by an allergic reaction. Food, environmental factors, drugs, radiological contrast agents and some disease states are among the etiological factors that trigger an allergic reaction. Kounis syndrome is a relatively rarely recognized cause of myocardial infarction, which is most likely due to its underdiagnosis. The presented case concerns a patient with a history of ischemic heart disease after coronary angioplasty. Until the insect stings, the course of the angina was stable. The course of the allergic reaction was turbulent and met the criteria for anaphylactic shock. Subsequently, the patient developed unstable angina. The clinical picture and additional tests allowed to diagnose a myocardial infarction in the patient. The coincidence of myocardial infarction with a history of an insect sting allows for the recognition of an allergic reaction as a trigger for acute coronary syndrome. The described case highlights the need for a multidisciplinary approach to the patient and regular supervision during the use of specific immunotherapy in the course of allergy to Hymenoptera venom, as well as the inclusion of Kounis syndrome in the differential diagnosis of acute coronary syndromes.

AbstractST-segment elevation myocardial infarction (STEMI) is a life-threatening condition that requires emergent, complex, well-coordinated treatment. Although the primary goal of treatment is simple to describe—reperfusion as quickly as possible—the management process is complicated and is affected by multiple factors including location, patient, and practitioner characteristics. Hence, this narrative review will discuss the recommended management and treatment strategies of STEMI in the circumstances.

Kounis syndrome or allergic myocardial infarction is an acute coronary syndrome in the course of an allergic reaction. In allergic patients in response to a specific condition - nourishment, inhalation, environmental substances, drug or insect bite there is an allergic reaction involving many different cells and mediators that can cause coronary artery spasm or initiate the process of rupture and activation of atherosclerotic plaque resulting in acute coronary syndrome. The paper describes a case of a young man with allergy to pollen and confirmed sensitization to nuts, who developed a full-blown anaphylactic shock after eating the nut mix and experienced a rapidly passing acute coronary syndrome with troponin up to 4.7 μg/L. An increased concentration of tryptase (15 μg/L), total IgE (> 3,000 IU/mL) and specific anti-nut IgE (55.1 kUA/L) were found. Based on the course of the disease and the results of allergic and cardiac tests, allergic type 1 myocardial infarction, i.e. caused by coronary artery spasm, was diagnosed. During the hospitalization, the patient’s condition improved quickly and after a few days he left the hospital without the signs of permanent damage to the heart muscle.

Abstract Background Loeffler’s endocarditis is an inflammatory cardiac condition of hypereosinophilic syndrome which rarely involves coronary artery. When coronary artery is involved, known as eosinophilic coronary periarteritis, the clinical presentation, electrocardiographic changes and troponin level are extremely nonspecific and may mimic acute coronary syndrome. It is very important to make differential diagnosis for ECPA in order to avoid the unnecessary further invasive coronary angiography. Case presentation We report a case with chest pain, ST-segment depression in electrocardiogram and increased troponin-I mimicking acute non-ST-segment elevation myocardial infarction. However, quick echocardiography showed endomyocardial thickening with normal regional wall motion, which corresponded to the characteristics of Loeffler’s endocarditis. Emergent blood analysis showed marked increase in eosinophils and computed tomography angiography found no significant stenosis of coronary artery. Manifestations of magnetic resonance imaging consisted with findings of echocardiography. Finally, the patient was diagnosed as Loeffler’s endocarditis and possible coronary spasm secondary to eosinophilic coronary periarteritis. Conclusion This case exhibits the crucial use of quick transthoracic echocardiography and the emergent hematological examination for differential diagnosis in such scenarios as often if electrocardiogram change mimicking myocardial infarction.

Abstract Allergic reactions related to drug use is a common entity presenting often from minor urticaria to life-threatening anaphylactoid reactions. A common but easily overlooked diagnosis, Kounis syndrome, is an established hypersensitivity coronary disorder induced by drugs, foods, environmental factors, and coronary stents that can present in the same way as non-allergy-induced acute coronary syndrome. Here within, we present a unique case of dual presentation of Kounis syndrome and prolonged QTc in a young patient after a single dose of Domperidone and Lansoprazole.

Abstract Introduction Obstructive sleep apnea (OSA) is prevalent and carries prognostic implication in patients with acute coronary syndrome (ACS). The relative contribution of pathophysiological mechanisms in ACS towards OSA is not well-studied. We examined the correlation between severity of OSA and myocardial necrosis, inflammation, wall stress, and fibrosis. Methods A total of 89 patients admitted with ACS underwent an overnight sleep study during index admission. Plasma levels of peak troponin I, high-sensitivity C-reactive protein (hs-CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP), and suppression of tumorigenicity 2 (ST2) were prospectively analyzed. Two patients diagnosed with central sleep apnea were excluded. Results The recruited patients were divided into no (AHI <5 events/hour, 9.2%), mild (5-<15, 27.6%), moderate (15-<30, 21.8%), and severe (≥30, 41.4%) OSA. The respective Epworth Sleepiness Scale scores were 3.8±3.7, 5.3±4.9, 4.0±2.8, and 5.5±4.5 (p=0.734). Compared to the no, mild and moderate OSA groups, the severe OSA group had a higher body mass index (p=0.005). They were also more likely to present with ST-segment elevation ACS (vs non-ST-segment elevation ACS) (p=0.041), have undergone previous coronary artery bypass grafting (p=0.013), demonstrate complete coronary occlusion during baseline coronary angiography (p=0.049), and have a larger left atrium diameter measured on echocardiography (p=0.029). Likewise, the severe OSA group had higher plasma levels of troponin I (10584±13078, 11699±20130, 19280±30670, 37571±31269 µg/L; p=0.017), hs-CRP (8.1±9.2, 23.1±52.3, 9.3±17.1, 39.4±44.7 mg/L; p=0.004), and NT-proBNP (667±604, 765±856, 636±728, 1395±1220 pg/mL; p=0.004), but not ST2 (p=0.10). After adjusting for the effects of the confounding variables, severe OSA was independently associated with troponin I (i.e., myocardial necrosis; OR 1.00003, 95% CI 1.000013-1.000048; p=0.001) and NT-proBNP (i.e., myocardial wall stress; OR 1.00081, 95% CI 1.00021-1.00141; p=0.008). Conclusion Severe OSA during the acute phase of ACS was associated with extensive myocardial necrosis and myocardial wall stress, but not with inflammation and myocardial fibrosis. Support Nil

Mast cells are abundant in the heart, among myocardial fibers, around coronary arteries, within arterial intima and intramural vessels, and in atherosclerotic plaques. Their mediators can be released during anaphylaxis and be responsible for acute coronary syndrome. This condition has been described as Kounis syndrome (KS). We report three cases of acute myocardial ischemia, which fulfill the definition for KS. In Cases 1 and 2, the association of intense chest pain with acute urticaria after an allergenic contact (wasp sting and betalactam antibiotic administration, respectively) was suspected to be an attack of angina related to an allergic reaction. No signs of an allergic reaction were observed in Case 3, but only the history of a wasp sting suggested its relationship to loss of consciousness and heart ischemia when hypersensitivity to venom was ascertained. These cases strongly recommend measurement of anaphylactic biomarkers, such as tryptase, during acute coronary syndromes to detect the possible involvement of an allergic reaction. Conversely, measurement of cardiac biomarkers during anaphylaxis, even without obvious signs of myocardial ischemia, might identify patients at risk of myocardial injury.
