The treatment of ST-segment elevation myocardial infarction has barriers depending on the geographic region. Primary coronary angioplasty is the treatment of choice, if it is performed on time and by experienced operators. However, when it is not available, the administration of fibrinolysis and referral for rescue angioplasty, in case of negative reperfusion, is the best strategy. In the same way, coronary angioplasty, as part of a pharmacoinvasive strategy, is the best alternative when there is positive reperfusion. The development of infarct treatment networks increases the number of patients reperfused within the recommended times and improves outcomes. In Latin America, national myocardial infarction treatment programs should focus on improving outcomes, and long-term success depends on working toward defined goals and enhancing functionality, therefore programs should develop capacity to measure their performance. The following document discusses all of these alternatives and suggests opportunities for improvement.

Anticoagulant treatment, together with antiplatelet therapy, plays an important role in the treatment of acute coronary syndromes. Its use is associated with a reduction in new ischemic events, stent thrombosis, and lower mortality. However, in clinical practice there is great heterogeneity in its use, leading to suboptimal results in treatment. This paper conducts a narrative review on the use of parenteral anticoagulants in patients with acute coronary syndromes, depending on the clinical scenario, as well as the revascularization strategy used and the bleeding risk. The different anticoagulant schemes available in acute coronary syndromes with and without segment ST elevation are addressed, based on the updated evidence. Finally, evidence-based strategies for risk stratification for bleeding and therapeutic management are developed.

There are increasing reports of a drastic drop in consultations and cardiovascular procedures (including urgencies and emergencies) in regions affected by the COVID-19 pandemic, with a consequent marked increase in total mortality that is not fully explained by COVID-19. Cardiovascular disease leads the ranking in deaths in adults in Argentina with 280 deaths per day, and in recent decades we have reduced its mortality by 20-30% through various evidence-based interventions. Herein we conducted predictive analyses to understand what could be the consequences of a worse implementation of those interventions. We estimate that less control of cardiovascular risk factors from April to October 2020 could cause up to 10 500 new preventable cases of cardiovascular disease. In terms of myocardial infarction, a drop from 40% to 60% of the reperfusion treatment could increase mortality by 3% to 5%. A marginal 10% to 15% increase in relative risk of cardiovascular death would be equivalent to an excess of 6000 to 9000 preventable deaths. In conclusion, given the high prevalence and fatality of cardiovascular disease, even a small negative impact on the efficacy of its care will translate into large numbers of people affected in Argentina. It is necessary to inform the authorities and educate the public so cardiovascular diseases and their risk factors remain a health priority, as long as resources exist and minimizing the risk of contagion and spread of the virus.
