Systemic thrombolysis and anticoagulation improved biomarker measurements in massive-like pulmonary embolism and severe COVID-19 pneumonia: a case report.

Background: From asymptomatic patients to severe acute respiratory distress syndrome, COVID-19 has a wide range of clinical presentations, and venous thromboembolism has emerged as a critical and frequent complication.

Case Summary: We present a case of a 69-year-old man with a clinical presentation of massive-like pulmonary embolism (PE) overlapping with severe COVID-19 pneumonia. The diagnosis was made based on hypotension, severe oxygen desaturation (33%), and right ventricular dysfunction (RVD).

[Heart transplant in Monterrey, Nuevo León].

Heart failure constantly increases its incidence and prevalence in our society, it was imperative to start a heart transplant program to improve the survival rates of patients with end stages of the disease. Legal issues made impossible to transplant patients out of Mexico City until recent years. Even with an acute hemodynamic and clinic improvement after the transplant, these patients frequently develop complications such as graft rejection or opportunistic infections due to the immunosuppressive schemes increasing the morbidity and mortality of the procedure.

[Haemostatic and inflammation markers in acute coronary syndromes and its relationship with adverse cardiovascular events].

Background: In acute coronary syndromes (ACS) interaction among several haemostatic (S and C protein, antitrhombin Ill, C protein resistance, plasminogen, alpha 2-antiplasmi and inflammatory factors (white cell blood count, fibrinogen, reactive C protein) could have association with recurrent thrombosis and recurrence ischemia, reinfarction, shock and cardiovascular mortality.

Methods: Prospective, controlled, with a six-year follow-up trial. END-POINT: Prove in acute phase and in a follow-up association among inflammatory, coagulation and fibrinolysis markers with cardiovascular adverse events.

[Heart transplant in "Nuevo Leon": the first 33 cases].

Heart failure is one of the most important causes of death worldwide. Heart transplant is the last effective alternative when the medical and surgical treatments have failed in patients with end stage heart failure, giving them an 80% one year survival rate. Unfortunately, during the outcome, the heart transplant patients can develop complications such as graft rejection and opportunistic infections because of the use of immunosuppressive therapy.

[Importance of tumor necrosis factor-alpha in the pathogenesis of heart failure].

Clinical and experimental evidence demonstrating the effects of tumor necrosis factor-alpha (TNF-alpha) in patients with heart failure continues to accumulate. It is well established that high concentrations of TNF-alpha appear in the circulation of patients with heart failure and that these levels have a directly proportional correlation with the patient's functional class. TNF-alpha levels also show a linear relation with prognosis.
