Since the last incidence, no inpatient hospitalizations have been reported.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Background&lt;/h3&gt;&lt;div&gt;Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. It is due to abnormal electrical activity within the atria of the heart, causing them to fibrillate. This arrhythmia may be paroxysmal (less than seven days) or persistent (more than seven days) (1). Researcher studies have found that Human Immunodeficiency Virus (HIV)-positive patients had an incidence of 18.2 AF diagnoses per thousand person-years, compared to 8.9 in patients without HIV (2). Non-pulmonary vein triggers are highly prevalent in HIV-positive AF patients and the mid- and long-term arrhythmia recurrence was observed to be mostly driven by those triggers (3). We present a patient who represents part of the growing study population of young HIV-1 positive male associated with arrhythmia recurrence.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;The prothrombotic nature of HIV infection is well-documented (4). It is believed that HIV-1 infection elevates stroke risk via systemic mechanisms such as low-grade inflammation and heightened oxidative stress, or through direct cardiac toxicity potentially leading to AF (5). A key consideration in the treatment of atrial fibrillation in patients with HIV‐1 who are in combination antiretroviral therapy (ART), is the significant impact these drugs have on liver enzymes like CYP2C9 and CYP3A4 (6). These enzymes are crucial for metabolizing numerous medications, including various oral anticoagulants (6). Given this, there is a strong likelihood of interactions between vitamin K antagonists and ART, particularly with protease inhibitors (PIs) or non‐nucleoside reverse transcriptase inhibitors (NNRTIs) (7).&lt;/div&gt;&lt;div&gt;Additionally, ART regimens containing PIs with or","PeriodicalId":72173,"journal":{"name":"American journal of preventive cardiology","volume":"19 ","pages":"Article 100805"},"PeriodicalIF":4.3,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She returned to the ER three days later with chest pain. Despite initial plans for discharge with aggressive BP management using a nitro drip, her rising troponin levels necessitated overnight observation. Further cardiac cath revealed extensive SCAD (originating in the distal left main, extending into the circumflex, and terminating in the left PDA, as well as the obtuse marginal branch), worsening from the last angiogram done a week ago, likely due to uncontrolled hypertension. She was admitted to the ICU for 48 hours for heparin therapy and strict BP control, and was later discharged with instructions for close outpatient cardiology follow-up.</div></div><div><h3>Background</h3><div>SCAD emerges as an increasingly acknowledged etiology behind non-atherosclerotic acute coronary syndromes. SCAD is implicated in 0.1% to 0.4% of all acute coronary syndrome (ACS) occurrences and is re-sponsible for about 25% of ACS instances in women under 50 and less commonly in men ( less than 15% of instances affect men). Risk factors include female sex, pregnancy, fibromuscular dysplasia, and associations with genetic connective tissue disorders such as Marfan and Ehlers-Danlos syndromes. It most commonly occurs in the LAD artery. In 46 to 61% of instances, the diagonal and septal branches are also in-volved; 15 to 45% of cases involve the circumflex, ramus, and marginal branches. Affecting several coronary branches is uncommon, but may occur in 9 to 23% of patients. Diagnosis predominantly relies on coronary angiography, which identifies the false lumen and intramural hematoma resulting from intimal disruption and vasa vasorum bleeding. Treatment is primarily medical for cases without progression, hemodynamic instability, or significant myocardial involvement, utilizing aspirin, plavix, ACE inhibitors, beta blockers, and heparin. Refractory cases may necessitate interventional strategies like stenting, angioplasty, coronary artery bypass grafting (CABG), or percutaneous transluminal coronary angioplasty). Reoccurrence from HTN occurs in 10 to 30% of patients.</div></div><div><h3>Conclusions</h3><div>SCAD is becoming recognized as the cause of acute myocardial infarction, particularly in young female patients with low cardiovascular risks.</div></div>","PeriodicalId":72173,"journal":{"name":"American journal of preventive cardiology","volume":"19 ","pages":"Article 100820"},"PeriodicalIF":4.3,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142423108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
