The coronavirus disease 2019, also known as the COVID-19 pandemic has had a deleterious impact on daily living, with health and socioeconomic effects of a global magnitude. Acute coronary syndrome (ACS), an important cardiovascular disease with significant morbidity and mortality rates, has been frequently reported in patients with this novel virus. This review aims to discuss the potential associations between COVID-19 and ACS with the use of multiple databases, including but not limited to; PubMed, ScienceDirect, World Health Organization, and American Heart Association.We have explored the pathophysiology of ACS, focusing on COVID-19 in particular with the use of various works of literature that highlights the pattern of viral entry and replication via the angiotensin-converting enzyme II. The review has also discussed the impact of the pandemic on hospital admissions, diagnosis, and management of ACS patients, as well as briefly highlighted a possible link between the widely available COVID-19 vaccines and possible cardiovascular complications.The association between COVID-19 and ACS needs more in-depth studies to help establish whether there exists a direct causal and or inciting correlation between them. Understanding this association might lead to new research and treatment options for ACS patients.

Treatment-resistant hypertension (TRH) is defined as blood pressure levels that remain above the therapeutic goal despite concurrent use of three or more antihypertensive medications taken at maximally tolerated doses, one of which should be a diuretic. Additionally, individuals on four or more antihypertensive agents regardless of blood pressure are also considered to have TRH. Amongst people diagnosed with TRH, African American adults face a huge management gap, resulting in increased cardiovascular disease risk. The primary objective of this review was to identify the commonly encountered etiologies and extensively discuss the current management strategies of TRH with a particular focus on African Americans. Relevant studies were identified by analyzing scientific databases and journals such as PubMed, Cochrane, MEDLINE, Cureus, and American Heart Association (AHA). The studies identified and examined common causes of TRH, describing their pathophysiology and highlighting different treatment options for the respective etiologies. The most prevalent etiologies of TRH amongst African Americans were chronic kidney disease (CKD), renal artery stenosis (RAS), fibromuscular dysplasia, obstructive sleep apnea (OSA), endocrine causes (Conn syndrome, Cushing syndrome, etc.), sympathetic nervous system overactivity, lifestyle factors, inaccurate blood pressure measurement, and inappropriate treatment. Of the etiologies reviewed, OSA, lifestyle factors, and CKD exhibited a striking prevalence among the subpopulation studied. Unfortunately, there was a paucity of articles addressing this topic amongst African Americans, and therefore there was not a substantial appreciation of the prevalence of some of the identified etiologies in the population of interest. Thorough diagnostic testing for associated or underlying conditions provides a basis for successful management. This review brought to the fore the need for doctors and patients to collaborate in order to improve TRH management and help patients lead healthier lives.
