Killip scale reclassification according to lung ultrasound: Killip pLUS.

AIM: The Killip scale remains a fundamental tool for prognostic assessment in ST-segment elevation myocardial infarction (STEMI) due to its simplicity and predictive value. Lung ultrasound (LUS) has emerged as a valuable adjunct for diagnosing and predicting outcomes in heart failure (HF) and STEMI patients, even those with subclinical congestion. We created a new classification (Killip pLUS), which reclassifies Killip I and II patients into an intermediate category (Killip I pLUS) based on LUS results. This category included Killip I patients and ≥1 positive zone (≥3 B-lines) and Killip II with 0 positive zones. We aimed to evaluate this new classification by comparing it with the Killip scale and a previous LUS-based reclassification scale (LUCK scale). METHODS AND RESULTS: LUS was performed within 24 hours of admission in a multicenter cohort of 373 patients admitted for STEMI. In-hospital mortality and major adverse cardiovascular events (MACE) within one year after admission, comprising mortality or readmission for heart failure (HF), acute coronary syndrome, or stroke, were analyzed. When predicting in-hospital mortality, the global comparison of these three classifications was statistically significant: Killip pLUS AUC 0.90 (95% CI 0.85-0.95) vs. Killip AUC 0.85 (95% CI 0.73-0.96) vs. LUCK 0.83 (95% CI 0.70-0.95), p=0.024. To predict events during follow-up, the comparison between scales was also significant: Killip pLUS 0.77 (95% CI 0.71-0.85) vs. Killip 0.72 (95% CI 0.65-0-79) vs. LUCK 0.73 (95% CI 0.66-0.81), p=0.033. CONCLUSIONS: The Killip pLUS scale provides enhanced risk stratification compared to the Killip and LUCK scales while preserving simplicity.

Subclinical congestion assessed by lung ultrasound in ST segment elevation myocardial infarction.

OBJECTIVE: We evaluated the prognostic value of subclinical congestion assessed by lung ultrasound (LUS) in patients admitted for ST segment elevation myocardial infarction (STEMI). METHODS: This was a multicentre study that prospectively enrolled 312 patients admitted for STEMI without signs of heart failure (HF) at admission. LUS was performed during the first 24 hours after revascularisation and classified patients as having either wet lung (three or more B-lines in at least one lung field) or dry lung. The primary endpoint was a composite of acute HF, cardiogenic shock or death during hospitalisation. The secondary endpoint was a composite of readmission for HF or new acute coronary syndrome or death during 30-day follow-up. Zwolle score was calculated in all patients to assess predictive improvement by adding the result of the LUS to this score. RESULTS: 14 patients (31.1%) in the wet lung group presented the primary endpoint vs 7 (2.6%) in the dry lung group (adjusted RR 6.0, 95% CI 2.3 to 16.2, p=0.007). The secondary endpoint occurred in five patients (11.6%) in the wet lung group and in three (1.2%) in the dry lung group (adjusted HR 5.4, 95% CI 1.0 to 28.7, p=0.049). Addition of LUS improved the ability of the Zwolle score to predict the follow-up composite endpoint (net reclassification improvement 0.99). LUS showed a very high negative predictive value in predicting in-hospital and follow-up endpoints (97.4% and 98.9%, respectively). CONCLUSION: Early subclinical pulmonary congestion identified by LUS in patients with Killip I STEMI at hospital admission is associated with adverse outcomes during hospitalisation and 30-day follow-up.

"Impact of age on management and prognosis of resuscitated sudden cardiac death patients".

Background: Sudden cardiac death (SCD) has a great impact on healthcare due to cardiologic and neurological complications. Admissions of elderly people in Cardiology Intensive Care Units have increased. We assessed the impact of age in presentation, therapeutic management and in vital and neurological prognosis of SCD patients. Methods: We carried out a retrospective, observational, multicenter registry of patients who were admitted with a SCD in 5 tertiary hospitals from January 2013 to December 2020. We divided our cohort into two groups (patients < 80 years and ≥ 80 years). Clinical, analytical and hemodynamic variables as well as in-hospital management were registered and compared between groups. The degree of neurological dysfunction, vital status at discharge and the influence of age on them were also reviewed. Results: We reviewed 1160 patients admitted with a SCD. 11.3% were ≥ 80 years. Use of new antiplatelet agents, performance of a coronary angiography, use of pulmonary artery catheter and temperature control were less carried out in the elderly. Age, non-shockable rhythm, Killip class > 1 at admission, time to CPR initiation > 5 min, time to ROSC > 20 min and lactate > 2 mmol/L were independent predictors for in-hospital mortality. Non-shockable rhythm, Killip class > 1 at admission, time to CPR initiation > 5 min and time to ROSC > 20 min but not age were independent predictors for poor neurological outcomes. Conclusions: Age determined a less aggressive management and it was associated with a worse vital prognosis in patients admitted with a SCD. Nevertheless, age was not associated with worse neurological outcomes.

An Exceptional Cause of Acute Right Heart Failure: Isolated Right Ventricular Takotsubo Syndrome.

We describe a patient with of acute right ventricular dysfunction secondary to right ventricular isolated Takotsubo syndrome (TTS). The importance of appropriate differential diagnosis for acute right ventricular dysfunction differential diagnosis of acute right ventricular dysfunction and the differences in diagnosis and management of right ventricular TTS and typical left ventricular TTS are highlighted. (Level of Difficulty: Intermediate.).
