RESUMEN

We present the case of a 40-year-old male without cardiovascular risk factors, who was admitted to our hospital due to chest pain. The electrocardiogram showed a typical pattern, already described, known as Wellens syndrome type 1 or A, characterized by ST segment elevation <1 mm and biphasic T wave in lead V3. Was diagnosed of acute myocardial infarction without ST elevation, TIMI 3 and GRACE score 66 points. This electrocardiographic pattern is of high risk, beyond the stratifying scores, since it correlates with severe injury to the anterior descending artery at the proximal level and requires percutaneous intervention without delay. The coronary angiography revealed 3 severe lesions: the proximal and middle thirds of the left anterior descending artery and the first diagonal. We highlight the validity of this electrocardiographic pattern, described more than 40 years ago, to identify and stratify patients with acute coronary syndrome.

Se presenta el caso de un varón de 40 años sin antecedentes cardiovasculares, que ingresó a nuestro centro por dolor precordial. En el electrocardiograma se evidenció un patrón típico, ya descrito, conocido como síndrome de Wellens tipo 1 o A, caracterizado por supradesnivel del ST < 1 mm y onda T bifásica en la derivación V3. Se diagnosticó infarto agudo de miocardio sin elevación del ST, TIMI 3 y GRACE score 66 puntos. Este patrón electrocardiográfico es de alto riesgo, más allá de los puntajes estratificadores, dado que se correlaciona con lesión grave en la arteria descendente anterior a nivel proximal y requiere intervención percutánea sin demoras. En la coronariografía se evidenciaron 3 lesiones graves: tercio proximal y medio de la arteria descendente anterior y primera diagonal. Destacamos la vigencia de este patrón electrocardiográfico, descrito hace más de 40 años, para identificar y estratificar a pacientes con síndrome coronario agudo.

RESUMEN

OBJECTIVE: This study aimed to assess the effects of sperm DNA fragmentation in parents belonging to different age groups. The couples included in the study comprised normozoospermic men and infertile women undergoing conventional IVF. METHODS: The results obtained from 163 conventional IVF cycles were analyzed retrospectively. The couples enrolled in the study included women aged between 30 and 37 years. Sperm DNA fragmentation was studied using the TUNEL assay. The patients were split into four groups based on male age and sperm DNA fragmentation, as follows: Group 1: ≤39 years and TUNEL assay ≤20%; Group 2: ≤39 years and TUNEL assay >20%; Group 3: ≥40 years and TUNEL assay ≤20%; and Group 4: ≥40 years and TUNEL assay >20%. RESULTS: No significant differences were found in semen parameters or fertilization rates between groups. Groups with <20% sperm DNA fragmentation showed significant differences in other parameters, including higher blastocyst formation rate (Group 1: 63% and Group 3: 60% vs. Group 2: 43% and Group 4: 41%, p<0.05) and higher expanded blastocyst formation rate (Group 1: 42% and Group 3: 40% vs. Group 2: 21% and Group 4: 18%, p<0.05). Miscarriage rate was significantly higher in Group 4 (42% and 46% vs. 5%, 25% and 5% in Groups 1, 2 and 3, respectively, p<0.05). CONCLUSIONS: Our results showed lower blastocyst formation rates from IVF when males had high levels of sperm DNA fragmentation. Higher miscarriage rates were also observed in couples with males aged 40+ years. These results reinforce the need to inform couples with male partners aged 40+ years about the potential risks inherent to fertility treatment.
