Pharmacological reperfusion remains the primary strategy for ST-elevation myocardial infarction (STEMI) in low- and medium-income countries. Literature has reported inconsistent incidences and outcomes of failed thrombolysis (FT). This study aimed to identify the incidence, mortality outcomes and predictors of FT in STEMI pharmacological reperfusion. ⋯ History of stroke (aOR 6.144, p = 0.004) and heart rate ≥ 100 bpm at presentation (aOR 2.216, p = 0.015) were the predictors of FT in STEMI patients who received tenecteplase. Mortality following STEMI thrombolysis remained high in our population and was attributed to FT. Identified predictors of FT enable early risk stratification to evaluate the patients' prognosis to manage them better.

Retrospective study comparing pulmonary hypertension risk in systemic sclerosis (SSc) and non-SSc interstitial lung disease patients with usual interstitial pneumonia (UIP) and non-specific interstitial pneumonia (NSIP). Retrospective analysis of 144 interstitial lung disease patients, 53 SSc (32 UIP and 21 NSIP) and 91 non-SSc (47 UIP and 44 NSIP). Pulmonary hypertension was diagnosed as pulmonary systolic artery pressure (PAPs) > 25 mmHg. ⋯ Frequency of patients with PAP > 25 mmHg in SSc-UIP group was 60% higher in comparison to control-UIP (OR = 1.62, 95% CI 0.51-5.16) and SSc-NSIP (OR = 1.60, 95% CI 0.45-5.70) groups. Logistic regression analysis estimating the linear trend per ten-unit increase in PAPs levels demonstrated an increment for the SSc-UIP group compared to the control-UIP (OR = 2.64, 95% CI 1.25-5.58, p = 0.01) and the control-NSIP (OR = 6.34, 95% CI 2.82-14.3, p < 0.001) groups. The case-control study confirms that pulmonary hypertension is frequently found in SSc patients and demonstrates, for the first time, a significant increased risk of pulmonary hypertension among SSc-UIP patients.
