Qué es un mini ACV y cómo identificar los síntomas para actuar rápido

Dos estudios reciente revelaron las secuelas de los ataques isquémicos transitorios (AIT), comúnmente conocidos como mini accidentes cerebrovasculares, mini ACV o micro ictus.
Como publicó Infobae, este tipo de episodio, que implica un bloqueo temporal del flujo sanguíneo al cerebro, podría dejar efectos persistentes y significativos en la salud de los pacientes, según los hallazgos publicados en la revista Neurology, la revista médica de la Academia Estadounidense de Neurología.
El análisis realizado por la Universidad de Aalborg en Dinamarca, evaluó a 354 participantes con una edad promedio de 70 años, y mostró que más del 50% de las personas que experimentaron un “mini ACV” reportaron fatiga prolongada que podía durar hasta un año.
La fatiga se presentó en diferentes formas: desde un cansancio general y físico hasta una reducción en la actividad, disminución de la motivación y agotamiento mental. Además, el 61% de los participantes señaló experimentar este síntoma solo dos semanas después de haber salido del hospital, y un 54% continuó sintiéndolo hasta un año después del evento.

Los investigadores, liderados por el doctor Boris Modrau, profesor del Hospital de la Universidad de Aalborg, remarcaron que estas secuelas tras un AIT no podían ser explicadas por la presencia de coágulos de sangre persistentes, ya que los escáneres cerebrales no mostraron diferencias significativas entre pacientes con y sin fatiga.
El equipo también identificó que la ansiedad o depresión previas a un mini ACV eran dos veces más comunes entre aquellos que reportaban fatiga prolongada.
Esta asociación sugiere que, además del AIT en sí, factores emocionales y psicológicos tienen una incidencia en la forma en que los pacientes experimentan la fatiga continua, por lo los médicos piden prestar una atención más integral post-mini ACV que incluya la evaluación y manejo de estas condiciones psicológicas.
El estudio indicó que el seguimiento a pacientes diagnosticados con AIT durante las semanas y meses posteriores al incidente podría ser vital para identificar aquellos que podrían necesitar atención especializada para contrarrestar los efectos de esta fatiga prolongada, mejorando así la calidad de vida y reduciendo el riesgo de complicaciones futuras.

Otro estudio, publicado en en JAMA Neurology en febrero de este año, reveló que los AIT pueden tener un impacto duradero en la cognición.
Según el autor principal de la investigación, el neuropsicólogo Víctor Del Bene de la Universidad de Alabama en Birmingham, el deterioro cognitivo tras un AIT es comparable al de un ictus completo, aunque los síntomas iniciales se resuelvan rápidamente. El hallazgo subraya la importancia de tomar en serio los AIT, ya que pueden alterar la capacidad cognitiva de las personas a largo plazo.
El estudio “Deterioro cognitivo tras un primer ataque isquémico transitorio”, de la Universidad de Alabama en Birmingham, analizó datos de más de 30.000 participantes mayores de 45 años sin antecedentes de ictus o AIT.
Los investigadores encontraron que, aunque inicialmente no se observa un cambio brusco en la cognición tras un AIT, cinco años después, el deterioro cognitivo es evidente y comparable al de quienes han sufrido un ictus. Este deterioro no se debe a factores demográficos, enfermedades crónicas o envejecimiento normal, sino al propio AIT.
Eric Smith, neurólogo de la Universidad de Calgary, enfatizó en un editorial adjunto al estudio publicado en JAMA Neurology que los AIT no son tan transitorios como se pensaba. Aunque no siempre conducen a demencia, alteran la trayectoria cognitiva de las personas. Además, otros factores de riesgo, como enfermedades cardíacas, diabetes o tabaquismo, pueden aumentar el riesgo de deterioro cognitivo y demencia con el tiempo.
Un accidente isquémico transitorio (AIT) o mini ACV es una obstrucción temporal del flujo sanguíneo al cerebro. El coágulo suele disolverse por sí solo o desprenderse, y los síntomas suelen durar menos de cinco minutos, según define la American Stroke Association, una división de la Asociación Estadounidense del Corazón (AHA, por sus siglas en inglés)
Los síntomas que indican un posible AIT, como dificultades para mantener el equilibrio, alteraciones visuales, asimetría facial o fallos en el habla, requieren atención médica de urgencia. Es clave que el paciente acceda rápidamente a un centro de salud para obtener un diagnóstico y recibir el tratamiento necesario.
El acrónimo R.A.P.I.D.O. es una regla nemotécnica que recomiendan los cardiólogos y neurólogos para reconocer de forma sencilla los primeros signos de un ACV. Los expertos insisten en que tanto pacientes como familiares deben actuar de inmediato al identificar uno o más de estos síntomas.
– R: Rostro caído
– A: Alteración en el equilibrio
– P: Pérdida de fuerza de brazo y/o pierna
– I: Impedimento visual repentino
– D: Dificultad para hablar
– O: Obtener asistencia médica

A pesar de que los síntomas de un AIT tienden a desaparecer rápidamente, en general en cuestión de minutos, no buscar tratamiento inmediato puede resultar en riesgos graves. Estos incluyen un riesgo elevado de sufrir un ACV completo en el futuro cercano.
Las estadísticas indican que entre el 5% y el 20% de las personas que experimentan un AIT desarrollarán un ACV en los 90 días posteriores, y las las primeras 48 horas las más críticas en términos de riesgo.
La rápida resolución de los síntomas es uno de los principales factores que lleva a las personas a subestimar la gravedad de un AIT.
Sin embargo, la aparente transitoriedad no debería subestimarse. La visión de eventos como estos por parte de la comunidad médica también ha estado evolucionando. Algunos especialistas estiman que quizás un cambio terminológico podría reflejar mejor la gravedad de estos episodios y estimular respuestas más proactivas. Reemplazar el término “transitorio” por uno que refuerce su posible severidad podría ser una estrategia para mejorar la respuesta pública.

DHS shutdown drags into week two as Iran threat, SOTU clash complicate Hill talks

NEWYou can now listen to Fox News articles!
A government shutdown, big or small, is usually a front-and-center issue for lawmakers — but the most recent partial closure could be put on the back burner as Congress returns to several issues in Washington.
Senate Democrats and the White House are still at odds over funding the Department of Homeland Security (DHS), as the shutdown dragged into its tenth day. Neither side is budging, with the most recent concrete action coming early last week.
Trump, who proved pivotal in striking a funding truce with Senate Minority Leader Chuck Schumer, D-N.Y., in January, was not directly involved in recent negotiations.

Trump has not had any «direct conversations or correspondence» with congressional Democrats recently, White House press secretary Karoline Leavitt said, noting that the White House and its representatives have been handling the dialogue.
«But, of course, Democrats are the reason that the Department of Homeland Security is currently shut down,» she said. «They have chosen to act against the American people for political reasons.»
Senate Democrats offered a counter to the White House’s own counterproposal, which quickly was rejected as «unserious» by Leavitt. It’s a peculiar instance, given that this is the third shutdown during Trump’s second term, and neither side appears to be in a particular rush to end it.

Senate Majority Leader John Thune, R-S.D., told Fox News Digital that there’s «some room for give and take» in the negotiations, but remained firm in the GOP’s positioning against requiring Immigration and Customs Enforcement (ICE) agents from getting judicial warrants, unmasking or other reforms sought by Democrats that could increase risks for agents in the field.
«I felt like, you know, the last offer the White House put out there was a really — it was a good faith one, and it was clear to me that they’re attempting, in every way, to try and land this thing so we can get DHS funded,» Thune said.
Funding the agency will be a top priority for the upper chamber, but they’ll be delayed because of winter storms descending on the East Coast. The weather has caused the Senate to delay a vote on the original DHS spending bill until Tuesday night, ahead of Trump’s State of the Union address.
There are other issues that could get in the way of hashing out a deal, including a possible conflict with Iran and Trump’s desire to move ahead with tariffs without congressional approval.

Trump told reporters Friday that he was «considering» a limited military strike against Iran, which already has riled up some in Congress, who are demanding that lawmakers get a say on whether the U.S. strikes.
Sen. Tim Kaine, D-Va., said in a statement that he has a war powers resolution to block an attack on Iran filed and ready, and challenged his colleagues to vote against it.
«If some of my colleagues support war, then they should have the guts to vote for the war and to be held accountable by their constituents, rather than hiding under their desks,» Kaine said.

On the heels of the Supreme Court’s ruling to torpedo his sweeping duties, Trump is considering bypassing Congress to move ahead with another set of global 10% tariffs.
That comes as some Republicans are quietly celebrating the end of the duties, and others are open to working with the administration on a path forward for trade policy.
On tariffs, a Republican aide told Fox News that the GOP was «waiting to see what POTUS does next.»
«The State of the Union should be interesting,» they said.

Tourists trapped in Puerto Vallarta recount cartel retaliation after El Mencho killed

NEWYou can now listen to Fox News articles!
Following the reported killing of major cartel leader Nemesio Oseguera, known as El Mencho, multiple American tourists vacationing in Puerto Vallarta told Fox News Digital they unexpectedly found themselves in the middle of a violent cartel retaliation.
As airlines canceled flights and authorities issued shelter-in-place orders, stranded visitors reported cars set ablaze, suspected cartel members blocking major roads, and stores ransacked by looters — scenes some witnesses said made parts of the popular resort city feel like «a war breaking out in the streets.»
Witnesses said they were forced to evacuate their rooms, manage with limited hotel food, and even venture outside in search of meals while waiting for Mexican authorities to regain control of the city.
Staying at an Airbnb near a main road, Eugene Marchenko, 37, of Charleston, South Carolina, told Fox News Digital he woke up to blaring horns and saw six cars completely engulfed in flames just outside his balcony. He and his wife, who had arrived in Mexico only a day earlier, were forced to evacuate for several hours, fearing that a nearby fuel tanker, also ablaze, could explode.

«I looked down and they’re completely engulfed in flames,» Marchenko said. «It was six cars in total that burned and one fuel tanker.»
He said he watched a neighbor’s video showing men he believed to be cartel members forcing people out of their vehicles, then pouring gasoline and setting the cars on fire.
«They told the people to leave,» Marchenko said. «Then they were taking the gas and pouring the gas on the vehicle and waiting until everybody was clear before they were setting it on fire.»
Later in the afternoon, Marchenko ventured out to find food and said he saw pharmacies and corner stores completely burned down, adding that younger crowds had broken into nearby buildings to loot beer and cigarettes.

Videos obtained by Fox News Digital show a helicopter hovering above his building, circling as if searching for someone, while Mexican armed forces and armored vehicles moved through the streets below.
Public transportation and Ubers had come to a complete halt, Marchenko added, saying that even if flights resume, he is unsure how they would reach the airport.
Despite the chaos, Marchenko noted that no one appeared to panic.
«There’s definitely not any panic from almost nobody here,» he said. «I think it’s interesting, almost everybody was just annoyed more than anything.»

Adriana Belli, 49, another visitor from Miami, told Fox News Digital that she had planned to spend over a week in Mexico to attend a wedding in Guadalajara and celebrate a friend’s birthday in Mexico City.
Belli said the sudden outbreak of violence was especially shocking, noting that she had spoken with American tourists staying at her Marriott resort who insisted the area was extremely safe after visiting Puerto Vallarta for 24 years.
She added that guests who had gone to the airport were under lockdown and were managing with the limited food available.
«A lot of the other tourists who had early morning flights were actually able to get to the airport, but they are now locked down in the airport and unable to leave,» she said. «So what we heard from other guests is they are just sort of surviving off of granola bars.»

Another source staying at a separate resort told Fox News Digital that restaurants and room service had been shut down. Guests were brought to the lobby for what was described as «the last bit of food.»
He added that this was the first trip where he and his wife were away from their 4-year-old son, and that he had to call home to tell family members where to find their will.
«This is the first time we’ve ever been away from him. My wife was saying, ‘We’re never leaving him again,’» he said. «I had to call my mom today and, you know, just tell her, ‘Look, here’s where my will is. We just created this. I don’t want you to panic, but I may need you to stay a couple days extra with my son.’»

He added that, despite the area appearing like a war zone, he is remaining optimistic that the authorities will restore order in the coming days.
Mexico’s Defense Department said Sunday that Oseguera was killed in a military operation. The news reportedly triggered widespread unrest and uncertainty across multiple states as Mexican authorities worked to stabilize the region.
